A 400 crank in a 305?
Are there aluminum heads for a 305?
Would a lumpy idle cam and the other two mentioned above be able to be fed by a stock 89 TPI unit off a Iroc with a custom chip. Would it put a Truck into the 13's? Just a debate between me and another board member somewhere else. Help me out guys

89 Trans Am Turbo 3.8L All stock 43,000 miles #1053 of 1555

Past Thirdgen:
86 Trans Am w/ built 355TPI with SLP goodies and too much other stuff to List. One sweet *** car, wish I would have had a good enough Job to pay insurance on three cars so I could keep it, but for a 89 Turbo Trans Am w/ Low miles, I think I made the right choice!

 

dont put a high duration cam in with tpi. screws with computer. a 400 crank will go in a 305, any small block head will bolt-on to this combo get a set of afrs or sportsman heads, just dont use the 305 heads your thinking about this engine is meant for high rpm and race use and is expensive to build better to just build a 406 roller or 383 roller. with this combination if normally asperated id use 24 or 26perhr. injectors. if NOS is used then 36perhr. injectors. this should put a truck into 13's pretty efficently with some 3.42's and suspension mods.

You misunderstood me. This guy made a BS post about a Truck that could run 13's with a system like I described, wasn'r specific about the cam profile or what heads he had, but he siad it had flat tops.
I simply was telling him I had too much experience with TPIs to believe a stock unit could feed a 305 built like that into the 13's. Especially setting on a 3.07? gear. Thats hat he said he had???? Never knew there was a 3.07 gear for any GM housing. Then the fact that there is now way the TPI could feed the cam's RPM range if it bumped at idle.

 

RHS used to make a 334 stroker. A 305 with a 400 crake. Made about 330 hp. Could that run 13s on a TPI, yep... but it would be a dog otherwise.

 

Yes it can be done. You end up with a 331, or if the 305 block is .030 over, a 334. It costs hundreds of dollars more than building a 350, and you get less power. All in all, it's a great example of using your own money to injure your situation instead of using it to improve it.

There are not AFAIK any aluminum heads specifically for a 305; but any number of aluminum heads in general can be made to work at least to some extent on one. Even Al L98 heads will work.

Of course the cam thing is pure crap. Stock TPI does not respond well to big cams; you can make a car go slower by putting too big of a cam under one.

I'd be inclined to agree that the whole deal is BS, unless the truck is significantly lightened, and has had something done to give it some traction. I had a friend who put a L69/T-5 into a S truck once; it would literally fry the tires all the way down the track, and ran mid 15s; then he put a Comp 292 cam and a SP2P and a Holley 750 on it, and it fried the tires even more, and ran high 14s, until it twisted the T-5's mainshaft in half. This was a completely stock-bodied truck.

Considering that a TPI 350 in a properly set up Camaro (lighter than a truck) is really tough to get very far into the 13s, this sounds like a bunch of some loudmouth polishing his wood at your expense. People like that are best left ignored IMHO, they can go off in a corner someplace and pleasure themselves with their stupidity, and let those of us that actually accomplish something go about our business.
