So I'm finalizing my decision just wondering what everyone would think it would make flywheel hp 427 dart afr 245s tbss intake 226/234 cam 600/600 lift 111 lsa 10:5:1 compression 1 7/8s long tube headers its going in a lifted 1500hd with 4.56 gearsvand 35s

 

500-550 at the flex plate?

 

578 at the flywheel, whatever. Put a blower cam and blower on that truck.

 

570 With the TBSS

605 with a Fast & 105mm TB

 

It's hard to say honestly I did see a 408 with ls3s to 630hp with a smaller cam once I'd be happy with it if it broke that mark

 

If you are staying NA then you need more compression

 

If I really like a tvs 2650 or a centrifigal pro charger how much of a difference would it make?

 

About 100% more power than N/A...
