I had a 305 in an 86 Z28 and I had a budget of $2500 for my engine. So I picked up a vortec 350 (2 bolt) from summit @ $2200 and an intake from professional products. And since the car was carbureted from the factory I wasn’t changing anything major and man what a difference 95 extra horsepower makes. Since then I’ve installed ls6 valve springs and an eBay lt4 hot cam and the car dynoed at 240 hp at the tires, doesn’t sound like much but when you figure drive train loss through the 700r4 I’m making stock ls1 power for less than $3000. Now I just need a stick trans and it’ll be “done”

TBI heads work well for a truck with an RV / Torque Camshaft, like the affordable Melling MTC-1, and a small vacuum secondary 4 barrel with a dual plane intake. You'll have all sorts of torque with great drivability. The camshaft curve is idle to 4,500 rpm and the TBI heads flow to 3,500 / 4,000. I've built several truck motors with this combination that pull extremely strong with great fuel mileage. It's all about what you are trying to achieve. If I was building something with more mid and upper range RPM oomph, JEGS and Summit Racing both have brand new heads for low $300ish each. They offer an old school 2.02 intake valve, 72cc chamber, head and a Vortec form factor.

One thing you forgot to mention is that on the right side exhaust manifold rear flange is that sometime in the eighties they made the bolt pattern wider on the rear of the manifold. Earlier heads did not have both bolt holes, so trying to put earlier heads on a later engine could cause problems fitting up the manifold. I learned this lesson the hard way. The rest of your information is very good.

1.94/1.5 “valve heads CAN be run on a 305 block. I’ve seen it done and have done it myself. I have stepped up to 350s in all of my small block projects, but I give 305s credit where they are due. If you have an extreme budget, a simple heads+cam 305 is a great choice for a little 300 hp runner. Milled Vortec heads and mild .500” lift hyd.. roller cams work great on them with 9:1 compression. I did it and made about 325 hp in my old IROC with a COMP XR270HR. Still wasn’t enough for me, though. 305 HO ‘601/416/081 casting heads work great on 350s as well. With a .039” head gasket and the 58cc chambers, you get 9.9:1 compression. But that gets you nowhere unless you port those heads, and in the case of a ‘416 casting head, can grant over 220 cfm hand ported. Easy, cheap 375 hp engine if you run a well-matched cam. 305s in and of themselves are not good, but their parts are if they are applied on the right combination.

Agreed, my buddy spent thousands on intake manifold, cam & springs, exhaust headers, carb and ignition in his goody Cutlass...I dropped in a 97’ vortec L31 with only a small Comp cam and aluminium intake just so I could scrap the TBI set up to have a carb which I installed a Quadrajet in my 4 door Buick Regal body, we both has 1 wheel peelers and I’ve smashed him time after time after time even allowing him a car length off the line and I still over take him within a few seconds, I spent maybe $1000 on everything motor, cam, intake, old ass carb and swap, he’s spent thousands around $350 and I make him look stupid with that 305, if I slapped in a bigger cam and springs it would be a joke. Stock junkyard vortecs have rollers cams, 4 bolt mains, 1 piece read mains, awesome flowing factory heads and the center bolt valve covers NEVER leak

I bought new vortec heads from Chevrolet in 2003 for the carburated 1981 350 that I was building. They performed very well. But they had one big drawback, because they did not have heat riser passages they are very cold blooded and don't run well unless you run carb heater hose to your air cleaner (or some other type of carb heater) if you expect to have your engine run right if you live were it gets extremely cold in the winter.

The 193 tbi heads actually respond very well to a straight pattern cam they flow pretty well on the exhaust side. The swirl ramp in the intake runner is the main reason they suck.

I rebuilt the motor in my 99 classic Tahoe. The heads were cracked. I replaced them with some summit vortec heads. Was told they were made from dart. I put an lt4 hot cam in with longtube headers. It runs good but not dialed in. I replaced the spider injectors with the better factory upgrade. 411 pcm which is somewhat right for the build. Deleted the emissions stuff and such. Anyway the larger tb's in the aftermarket is really expensive and limited. Want to swap over to a carbureted intake. What intake and carb would you recommend for a fairly mild build such as mine?

@chevypower42710 жыл бұрын
You forgot to mention the intake ports are more nicely done than the older style heads. Also for higher lift, the valve guide bosses have to be machined. They also require self aligning rockers arms if im right, unless machined for guide plates and screw in studs. I had all that done on mine, and I believe, cost wise, it could have cost me nearly the same price as entry level aftermarket cylinder heads.

Great video. I have a 74 Camaro 350 engine with an eidelbrock performer intake with 4 barrel carb, middle bolts missing and 4 in the middle on the covers so I am assuming vortec and the cast exhaust manifolds that curl up (ram horn?) and I presume from the smooth idle a standard cam and my spark plugs are toasty brown and she runs sweet. Any idea what hp I may be getting from this setup. I’ve just bought the truck a 56 Chevy pickup and it really does move well ! Cheers for any valued advice.

the drawback of the TBI heads - they have swirl ports (first introduced in 1983 on the Cavalier 2.0L motor) designed 4 max fuel economy - the swirl ports produce a tornado effect (hence the Vortec nomenclature which was introduced in 1985 with the 4.3L); also, the 96+ Vortecs (used on the 4.3) - there is no aftermarket intake 4 the TBI or CPI setup which exists
