Crate Engines in NHRA?

[MikeFicacci]

The 396/375 is a crate engine minus the crankshaft. It was just done slowly and policed fairly well as the aftermarket parts were put on. It doesn't sound like NHRA is presently in the business of slow, moderate, properly-factored changes.

Chipper think about SS/GT/HA. Your present shortblock should be legal as a 350 300 horse you have to change heads and carb. Should be able to run under index esp. IHRA. ...Thanx Trevor

Actually, my engine is a dished piston version, using Lunati 350-170 slugs. (proper for the 77 350) Camshaft and top end are the big difference in in my engine, and where most of the money was spent of course. Would have been easy enough to swap heads (if not for the expense) but I just checked and the Lunati 350-170 is no longer an NHRA approved piston.

I wasn't trying to piss anyone off with the original post, I just got to wondering if it had ever been considered.

BTW, my ZZ4 Crate uses the exact same heads that a 1990 vette would in Stock eliminator, with 160cc runners, 1.94/1.50 valves, they are far from what everyone stereotypically thinks about CM heads. Just food for thought.

I heard a few years back that NHRA was considering it.
