As a 40year Custom Harley Davidson Fabricator & Builder, I just wanted to comment on your presentation of "How To". I thought they are very well done, informative and concise.

Love your videos man, short and sweet. You communicate the message very well. Thanks for sharing

Great video!! I like how you are detailed with information and you also provide tips and explain things like in your last video you explained what a roller motor is thanks for all the tips and advice keep up the good work.

You are correct if you know what you're doing already. Placing the TQ wrench at 12 o'clock helps ensure you remain within 1/4 to 1/2 turn to hit torque spec. If you do not keep that rule in effect you need different length rods and or shims. The way I did it is the proper way. Do it however you wish. This is how I do it. Centering roller in valve stem tip is accurate geometry.

This is an awesome series of videos, thanks for the great tips! Im looking at redoing the top end of my 69 302 and this is great for visual learners like me

You did this very well and was top notch with the explanation!!! Keep up the good work kiddo!!!

Excellent and easy to understand! Thank you!

I enjoy looking at these video's you have on rebuilding engine. You done a GREAT job on this.... I have a 4.6L 281Cu. In. V8 that i will be braking down soon.

You post up extremely detailed videos. Best videos out as far as checking pushrod length, lifter installs, and basic valvetrain info in general. Thanks for these vids. Very helpful.

Like the trick with the dry marker!

I'll definitely be coming back to this video when it comes time for this for me.

I find this useful, I have to build a 8.2 deck 302 stroker for my mustang to be boost friendly..

Of course I will be using shaft mount rockers though cool video...

When you're setting the rocker torque and checking pushrod length, are you pumping up your lifters by priming the oil pump? Also, did you notice any of your valves opening a bit when reaching final rocker torque?

are thos gt 40 p heads and what valve springs are you using

thank you

Are the lifters pumped up or are they dry? Does the pushrod push the lifter cup down to any degree at all when torqued it into place. Thanks

What if u don’t get the correct torque spec from the 1/4 to 1/2 turn ? Do u shim the pedestal mount or adjust the pushrod longer ?

What camshaft are you using in that build thanks

you don't need it centered you need it smallest thinnest witness mark first and if it's centered cool if not as long as it's in between the end of 1rst 3rd and beginning of 3rd 3rd of tip. but thinnest is what you want

what springs and stuff did you use???

Are dose rods good for e303 cam or 1.7 should i use??

Do stock push rods fit gt 40 3 bars direct bolt on?

I did what you said and it seems like I don't get enough threads. Like the PR is to long . At risk of sounding stupid I think maybe a little shorter PR. Maybe best to get a PR checker?

Good video but why didn't you use the Comp Cams pushrod checker and purposely make the rod length incorrect? Would have drove the point home.

Great vid for understanding these bits. I am a bit confused about one thing though: If 2 thousands have been taken off the heads, why would these have to be ADDED to the pushrod length? To me it seems logical that it should be subtracted, so that the pushrods are shortened now that the head is a bit lower.

I"m confused,if you shave 2 thou. off the heads don't you need a shorter push rod?It may explain way your runner mark went higher .Had you ordered the push rods 2thou. shorter your mark would have remained in the same area would it not?

I know i'm 9 years late, but from reading the comments i only seen on reply from the guy in the video telling to go to hes website. I have 3 of these 302 and one will be rebuilt soon to put in my truck as the old 83 engine is under powered. Runs great but under powered , only 140 hp. 2 are roller motors and one is not.

I got a noise lifter on my 302 and watching your videos I think I can change them. Would upgrading the rockers be worth doing at this point

What lifters you use ?

On solid mount rollers (pedestal mount) pushrod length has nothing to do with geometry. The height of the pedestal changes the geometry.

i need help with my valve train. if someone can listen i xan try to explain my 302 issue

The instructions that came with my scorpions say 1/2 to 1 full turn. Then torque to 20 ft lbs. Wonder what changed from 1/4 back then to 1/2 now

hey man awesome videos thanks so much for the information I'm throwing on a set of gt40p heads with an explorer intake my question for you is can I use the stock "bolt on" style rockers from my e7 heads on the gt40p heads, I know you said in video pushrods are ok and for installing them do I just torque to spec 25 lbs as the manual says? any help would be much appreciated thanks!

If you had 2 thou. removed from your head, should you not have a 2 thou. shorter push rod, not longer?

From what I understand, you also need a mechanical roller lifter so the lifter does not collapse when using the actual valve springs and not the special ones made for this check.

How far do you think the lifter collapsed by turning it a 1/2 turn? I'm about to measure for my pushrods so I'm just curious. Thanks

If the base circle on the performance cam is .049 smaller than a Explorer cam or fox roller cam, then the pushrod should be 6.30 inches with GT40 heads and roller lifters with stock 1.6 rockers. He probably is forgetting to tell us the base circle on his cam is smaller than stock in his explanation.

Hi, I picked up a 69 mustang with a 302, the valves tips are different diameters and the exhaust valves have little metal caps on them that look like they are trying to equal the diameter of the intake valves. Do you know what is going on here ?

You got foam with yours??? Its 2018 now. I got cheap cardboard spacers and a box bout half as big.

I gess Im lost but if you take .002 off the head don't you need a smaller pushrod?

Hello, excuse me, I got the instructions for the lenght of the pushrods, can you tell me What exactly is the difference between the 289 & 302? as long as I can see everything for the 289 matches in the 302!

Please don't ever take these videos down

Amen

Painting the oil filter boss is a no no if any paint come off well you know i never do it just tape it off

I have a 90 foxbody GT. I bought it as is. and It has a 302 with TFS track heat intake manifold. with patriot 185 aluminum heads. It’s has gold 1.6 roller rockers. Not sure what brand? Also has a TrickFlow stage 2 camshaft. But the car isn’t performing like it should...it seems like it’s missing a bit. Very rough. I had the timing set twice. Added a billet distributor new coil new wires new plugs. Also Deleted the IAC and EGR. Runs a little better. Throttle response is on the $. Just it’s missing something. Fuel Pressure is at 40psi. Maybe it needs more fuel ? Thinking of switching the cam out. As was looking into what push rod length I needed. This video helped a lot. 👍🏼 the cam is made for TFS head specs would that matter if it was paired up with different set of heads.. my possible theory

hey could you help me and tell what push rod length would get me in the ball park with gt40p heads and comp cam xe270hr part 35-35-8 please help thanks and stock rocker arms

Can you tell me the exact part number of these rockers?

Is it true better the cam the less u hv to find push rod length but what is better ???

Push rod length has nothing to do with how the roller rolls across the valve tip. You adjust that by placing shims under the pedestals. Then you determine your correct push rod length.

You want the narrowest wear pattern possible and being in the center is not always where that is. Your wear pattern looks pretty wide.

I found an easier way. I put my stock pushrods in that are too long, nut spins on 5 turns to 0 lash. Take the pushrod out, spin nut down 5 turns, align the rocker to center of valve stem by counting turns past the 5. I ended up with .250 shorter than stock. Sharpie on valve stem and spin the motor over. Perfect. 7/16 rocker stud has .050 per full turn, 3/8 rocker stud is .042 per full turn. You dont have to get that technical by ordering pushrods .002 different. Lol. Smokey Yunick used to run his rockers towards the outside of the valve stem in order to cheat the class rules. Yes it wears your guides more. He used to achieve a .020 increase in lift by doing this. The angle of the fulcrum is changed.

Cody. Take a look at my website 302 budget build dot com. I list all part numbers etc on there. They're crane beehives. E303 cam.

Or u can get a thicker gasket

.002" , is less than the thickness of a paper- clip.... I don't see how that makes a REAL DIFFERENCE... the head porting is what's really gonna matter.

I am having trouble grasping this. You had 0.002 taken off your head. Why are you adding anything to your pushrod length? Your head is now 0.002" shorter which would mean squat to the pushrod because with hydraulic lifters, rollers included, you have to set a preload on the lifter so even though you have some meat taken off the head even using the OEM stock pushrod length for a roller engine you still set the preload and still obtain the same results. Next thing is your roller position over your valve stem tip. Why are you concerned about where it is touching on the valve tip? You do know that the rocker is a preset length and that as the valve is compressed the rocker tip is moving across the valve tip as you can see by the paint being rubbed off. That is why roller tips are better because they allow the rocker tip to roll over the tip of the valve vs rubbing across causing drag for the engine. Like wise I am wondering why you are also worried about torque on adjustable rocker arms. You set the cam in a position where your lifter is on the base circle tighten up the rocker arm till you cant spin the pushrod then go 1/2 to 1 full turn to set the lifter preload. I generally use 3/4 of a turn for my preloads and it works every time. So in the end I am trying to grasp why you did what you did. I am curious about your reasoning.

You didn’t show shit about having to measure for pushrods.

you are wrong..... Think a little harder
