so what is the big diff? i currently have a L48 350 in my car with tpi set up. what makes it such a dog? just the heads and cam?

 

L-48?????

 

never heard of a L48

 

L48 = generic 350 4-barrel from the 70s

Came in everything from Vettes to trucks to Z28s to El Caminos. Even if it had a different "L" number like trucks, it was still the same motor; for that matter, a 350 2-barrel was the same long block, with a different intake manifold, and everything else pretty much the same.

8.3:1, 882 heads, 929 cam, yadda yadda yadda

 

well i got one on my z28, but right now it has the tpi set up. is it an engine worth building? or should another 350 be looked into. keep in mind im looking to just hit maybe mid to low 13s n/a.

 

It has potential, you just need to replace everything except the shortblock, heads, cam, and intake.

 

I have an L48 out of a '79 Z28 in my Camaro.

Its definitely no fire breather. My old 5.0L HO motor was quite a bit faster than the 350 (L48) thats in it now.

Its a low compression motor with a crappy set of heads and a cam with no rocks at all.

It has potential, but you gotta replace almost everything in/on the block.
