Pump gas 572 hp guess

Post  tfsbbf466 on February 11th 2018, 11:38 am

I’m going to be dynoing this motor in the next few weeks and wondering what it should make. Here is the build list

A460 block
Scat forged crank 4.50
Scat 6.80 rods
Venolia pistons 11:1
FMS A460 heads ported 2.30” intake
FMS A460 intake
Pro systems 1200cfm
Custom solid roller 277/292 .800-.773 108ls
2 1/8 headers to 4” collector
No vacuum pump at this time

Motor will be going into a full size all steel stock suspension truck 4000lbs with a c6. Will also see a good amount of nitrous from an IS Real Street plate. Hoping it’s a bit faster then my cast crank TFS street headed 512 that blew apart last year lol

I will be very interested in what it makes as I am working on a 562 build 11:1 18 bolt TFS A460 head 2.350 intake valve build.

how much port work was done ? how do they flow?

They were ported years ago then touched up recently. Flowed around 410 at .800 on his bench. I never did get the flow sheet.
