That 620 hp is probably about right. I did not dyno it yet, but if feels like about 525-540 rwhp. I have no experience with NOS , but I'm sure it could handle quite a lot.

He lifted the heads at the Mile and is, I believe, looking to go 6-bolt.

NASCAR teams spend a 100,000 on a 358ci engine that makes only 900hp

I could be wrong but my ex boss is a nascar fan I think he told me that have rules about engine size and what mod they can used in the motor I don't know if that is tru please correct me if I'm wrong I don't knownothing about nascar

[camaro34]

Yea they are limited to 358ci small block but they put out over 900hp NA

Somewhere around 14.1 compression on a NASCAR engine.

The LSX 454R is the most powerful GM crate engine ever built.

The LSX 454R has a deck height of 9.700" making it a big block

It's not big block 454 .. It just has a taller deck.... Also a gm 454 LSx would not make it close to 2500 hp.

NASCAR engines are limited to 12:1

They actually made more power when they went to 12:1. Before they were running from 14:1 to 16:1.
