Ultimate 305 SBC Builds: Mild Street vs Stroker

Күн бұрын

The guys bring the well-known but anemic 305 Small Block Chevy into the shop by viewer request. They teardown a used and abused 305 and get it ready for some mild upgrades for the everyday hot rodder. The transformation continues as we assemble our Small Block Chevy with new upgrades. Once it's put together, we’ll put it on the dyno and see if the 305 can make respectable power with some modern touches. Then, we bring our it back for a second round of racier upgrades as we try and squeeze even more power out of this little small block.

My Dad and I test drove brand new Chevy Monza's with the, then new, 4.3 liter 262 Small block V8's and 4 Speed's. They were gutless so we ended up buying a brand new Oldsmobile Starfire Firenza with the 305 V8 and the 4 Speed. It was a blast to drive and much faster than the 262. Oddly we also test drove the new Buick Skyhawks but they had the 231 V6 engines that would end up in Dad's 87 Buick T-Type Grand National much later, but with a Turbo and intercooler.

@pinsandscrews6459 3 ай бұрын

Personally, I think what hurt the reputation of the 305 had a LOT to do with the emissions equipment and tunes from the factory compared to the effect the emissions equipment had on the 350. The quick route to more power was to throw in a stock 350, and, if you could get one with a 4bolt main, that was a bonus. Since you also already had the 350 out of the car, it was a simple job of throwing in a new cam and heads for even more power.

The next step up is to weld a washer to the bolt first then a nut to the washer and bolt, better chance of fusion that way with the cheap mig welders most guys are using. Most guys cold lap for the first bit due to too much stick out and not enough heat and don’t get any fusion to the bolt and the nut just comes right off until they get it hot enough after 10 attempts to actually fuse somewhere

@Anarchy-Is-Liberty 2 ай бұрын

@@jamesmedina2062 To be blunt.. gobs of torque!! Torque combined with horsepower is what makes things move, and move fast! Do the same exact build on a 305 and on a 400, and see what happens. The 400 will make approx. 65lbs ft more torque. It will lose about 8-10 hp on the top end, but the torque gained will win the race. Another benefit is, because the 400 has way more stroke, it moves the power band lower. So the 305 would operate (with a cam of 235 degrees duration @.050) from 4500-6500+ to the 400's range of 3500-5500+. Added benefit of being easier on parts, and longer lasting. Now, to make it actually fair, you could add another 0.1 to the rocker arm ratio (from 1.5 to 1.6), which would bring up the 400's hp and trq numbers even more. Because the engine has more stroke, that cam would actually be much smaller to the 400, so you could also use a bit larger cam to make up the difference. To bring the 400's rpm range up to that of the 305's, you'd want a duration @.050 of approx. 255, and about another 0.030 in lift (to stick with the original 1.5 rocker ratio). This would bring the 400's rpm range up near the 305's from 4500-6500+. Not only that, now you're making at least another 20+hp on top, and overall more torque throughout the rpm range. The cherry on top with the 400 now is, you're making in the neighborhood of an extra 15-20lbs ft of torque on the top end combined with the added hp, so massive power difference all the way around. Either way, I stick to my original comment... the 305 is a totally impractical build! Now, if you want to build it just because you want to, that's fine, it's your life, live it, I wont hold it against you, but it's still a totally impractical build. A V8 is a V8? Then why aren't people all racing with 283's instead of building 632's, and now over 900ci race engines?

I have yet to see you guys run a 327. Start off with the best heads (double hump) from back in the day (maybe ported and a good port matched intake) put flat tops in that makes about 10 to 1 with a dutnov grind 30/30 cam and a 650 carb. Then build it again with a lighter forged rotating assembly with lighter rods and pistons and good hardware. 11.5 to 1 compression is completely doable with aluminum pistons and heads with mls gaskets. Stick a healthy sollid roller cam to make power to about 7500-7800 rpms. Get a good set of AFR heads and a fully ported and polished edlebrock rpm intake with a carb spacer. Playing with different styles and widths could make good content then try a as cast vic jr then one with just the ports cleaned up both port matched to the AFRs of course. This could be a three part series. 1st Run the first engine with 91. 2nd the new combo and fully ported rpm air gap and different spacers with 91+race gas octane booster. 3rd with the vic jr as cast 91+ booster and then ported with race gas. It would just be cool and very interesting and enlightening to see/compare the difference hp/trq numbers to give people an idea where they could potentially save a lot of money and still make good numbers or if its worth spending just a couple hundred bucks and make awesome power. You guys do too much LS stuff and dont get me started on how many different small and big block Ford combos you've done..

I got to give it to you. I put off watching this thinking the same thing. 305? Then Pat goes into a Honing tutorial! This is what I want from my machinist. Excellence! Of course, as a builder, you must inspect and verify. Great knowledge, you can find them anywhere.

This proved what I've been telling all these young engine guys that think they tested a 327 chevy, Unless you were alive in my era you don't know about the cars or engine perfomace of my era !! If you test a 327 you'll need to test it right. leaded fuel (103 to 107 octane fuel) and high compression (11 to 1 or 12 to 1) and headers Some of the same engines ran better because the automobile industry wasn't perfect. Thank you Powernation for opening some people eyes.. But most us knew that 305 was in the 265 family.

Wow! Beautiful a story and I'm looking forward to to completing the process of seeing what is done! In the late 1960s I put a 327 and a 283 together and began a hobby, sometimes quite expensive, which has not left me yet, though I'm happily pursuing (at 80 years of age disappears to be totally appropriate). longevity and good function rather than short-term go fast!😅

I found that if you drill a hole into the center of a broken bolt before you weld the nut on, you get a better chance of getting the best chance of actually getting a bite into the bolt itself with the weld. Then shock it with a small ball peen hammer or air hammer as you're applying pressure to the nut. Then if it moves slightly, then go the opposite direction until it stops. Blast it with whatever you're choice is, and repeat until the threads turn freely as it comes out of whatever it was broken off inside. Tends to not break off the weld attaching the nut as often in my experience. PS How about a 1980 Pontiac 301 which was in the trans am for that year, as well as the turbo version. The NA version is what I've always been curious about seeing what it's capable of. I mean the DZ 302 was such a Bad asset, so why not the 301 Pontiac being equally as successful if possible. I don't know honestly why it can't be, even matching the specs, down to doing whatever is needed to cast iorn Pontiac heads, and doing everything possible to match cam intake carb which shouldn't be hard nowadays

The bolt is made out of steel, the block is made out of iron, which, which has a much higher melting point so you can safely torch out the steel without harming the block.
