the LT4 was an engine made my chevy and put into the 1996 grand sport corvette, a few impalas, and a few f bodies. its basically like an LT1, but some extra goodies...

I believe the lt4 has taller intake ports along with a different cam (not the lt4 hotcam) and lt4 specific intake.

the LT4 only came in corvette's from gm. there were just over a 100 installed into f bodies (ss's and firehawks), but they were converted by slp engineering. check out the specs, much more impressive engine over the LT1.
