Re: Chevrolet Performance Crate Engine 195hp vs 290hp
Getting caught up in the numbers game, are you.
That’s a normal thing!
Still a bit of a mismatch comparing true compression to cam duration. They say nominal 9 to 1. Translates to 8.7 to 1. Roller cam more forgiving though. And better heads.
With a sharp timing curve it’ll work. Their recommended timing is dismal. You need more than double their 8 initial.
What trans you running?
What convertor?
What rear gears?
Are you prepared for a lumpy idle cold blooded motor?
Not a set it and forget it motor.
