When we were deciding and ultimately ordered the LSX 376 for the '62 Impala --- I wanted the LSX 454 --- but the compression on the 376 is 9.0 vs the 11.0 of the 454 ---- and even GM Performance "advertises" the 376 as being built for supercharged or turbo'd.
Mine had a TVS 2300 blower added to it...
I have the 480hp LS3 in my '33 Ford being built at Brizio's.
Plenty of motor for a little '33 highboy!
