i guess this is more curiosity than anything...
anybody have one?
i mean like destroked it to run high revving.
from what i understood, they took the 350 back in the day, and threw a 283 crank in there, and it became the high revving 302
couldnt you basically do that to the lt1 sincei ts a 350 and has anyone done it?
let me hear your comments on it if you did

 

I'd imagine you could, but w/ old chevy style stuff it would be easy to make up the power difference w/ a high flow intake manifold and some bigass heads. I think you'd just be losing power if you destroked an lt1

 

Mine could rev to about 6800, but I keep it a bit lower because I don't think it has enough airflow to support it yet...48mmTB and stock airbox

LT4 CC306 363CI

 

What do you call a high reving LT1? My motor on the dyno was still pulling 529 FWHP at 7400 rpm. Would it go farther?
I am sure it would but it peaked at 6900 so no since in pushing it. 7400 will be my limit at the track.

 

if you mean high like 8k rpms then your gonna need an aftermarket ecm past 7k. That hit to the wallet right there would be the biggest drawback IMO.

They bored the 283 out and had a 301, which became known as a 302.

 

....you built an engine and you have the stock TB and AIRBOX!?!!

 

Yeah, it's the good ol' runnin outta money for a rental while waiting for parts to come in game.

That, and I have been spending all my money on other things. Like PCM's Opti's, MAP, MAF, IAC, TPS, and the whole damn engine. It's a 9K plus bill so far.

 

no he had it right the first time. it was a 350 block w/a 283 crank, which made the 400+hp 302 in the 1st gen z28s...

 

well, look at the article on here
its about the sema show 302 that they made out of a wrecked ss
they took the 4 in bore that 327 and 350 had back in the day, and threw a 283 crank in, hence 302 ci
for the sema one, they took an ls1 and did it
i just want to know if anybody has done it

 

Yes, they did that, but the bored out 283 was well before the 302 Z. It was never available from the factory, but was a well known hot rodder trick from the day.

 

Anything past 7K on a STOCK ECM = WASTE OF TIME

 

no man, i'm not asking if it's a waste of time
or that you would have to tune it to work right
i'm just wanting to know if anybody has done it, and what their comments are on it
thanks for the input though

 

Somebody on here, cant remember name, has a destroked supercharged LT1 producing almost 1000hp. The name has turbo in it, cant remember the rest. I think its a 346 maybe.

 

Spinning past 7 grand.........ACCEL DFI does the trick.
