too many variables, you need to be more specific.

 

How much power do you want to make?

Pump gas or race gas?

etc

Crossett is right, need more info. Also, don't forget this is a message board forthe free exchange of ideas concerning Hybrid Zs and it is the users responsibility to post and read posts for info and not get personalized emails. It just defeats the whole purpose of a message board.

Okay, these guys are right... We will help you all you want but need a little more information. Maybe this will help though.

 

Most feel that you want to stick with a 350+ cubic inch engine. Here are the common sbc engines and the order of preference as I see them.

 

383 (Stroker motor, uses 400 crank in a 350 block)

400 (Not nearly as common as 350 and more $ to build)

350 (Most common engine on the planet, dirt cheap parts)

327 (Very high revving engine, most feel its a little small. More expensive than a 350 to build)

305 (Engine in cheap and easy to come by but dont go there)

 

Transmissions in order of strength. Oh and by the way you really need an overdrive so thats all Ill list. (Just my best guess)

 

T56 (Manual 6sp used in corvettes late F bodies such as camaros)

700R4 (Auto 4sp used in many GM cars 86+ for the good ones)

200R4 (Auto 4sp Lighter and better gear ratios than the 700 harder to find and not as strong)

T-5 world class(Manual 5sp, 3ed generation F bodies with 350. Not recommended for much over stock power)

 

Give us some more info and we will help you out. You might want to also try to search function at the top of the page.

the 1970 lt1 was about the hottest carburated 350 I can remember and it was rated at 370hp,but with good aftermarket parts 400hp PLUS is fairly easy to get so tell us what your cars weight,trans,rear gear,ETC are and how much $$$$$$$$$ your willing to spend on the project and we can advise you on parts to purchase but keep in mind the engines displacement can be increased to 383 quite easily and that helps torque quite a bit and the extra displacement helps the hp also, and that the heads and cam must match the rpm levels your building the engine for.

i agree, the 70lt1 is it when it comes to 350 carb factory heat. no joke buildup from the factory big valve heads, four bolt main, no scrounging in the parts bin for this one, and thats

rare. hard to find, you would have to buy the car to get one used. 350 in general are easy

to find and its not very expensive to build any 350 hotter than that. i like my 327 because he wont die.

thanks for all the advise but this is going to be my first project car but i have high hopes i want to turbo or supercharge and i want to have and end result of 500+ horsepower on a modest budget but the engine 1970 LT1 sounds like a good start witha t56 trans

The original LT1 was a great motor rated at (what was it 370 hp or so). That said, its old technology, there are better heads and cam profiles these days and no reason not to take advantage of it. Let the original LT1's stay with they're number matching cars..
