Lt-1 - Lt-4 ??
I had a C4 years ago, then got into C3's for a long time. I have not done any research, but can someone tell me what the LT-1 & LT-4 engines are? Which years produced ? Was there an engine option on any C4 years?
Thanks,
Boatman

The LT4 was an upgrade option only avaiable in 1996, also had to have the 6 spd tranny (RPO ZF6). The LT4 gave you 30hp more then the standard 300hp in the LT1. Some say the LT4s have more then 30hp 
, but 30 is what GM claims.

here it is quick and dirty
'92-'93 had the Early LT1 300hp speed density
'94-'95 and '96 autos had the Late LT1 300hp MAF
'96 manuals had the LT4 330hp
As far as I know the only engine option was the ZR1

LT4 was for all 96 manuals.
Rated at 330Hp, actually has 350. It was underrated due to the LS1 coming out in 97 rated at 345.
