My Engine is nearly complete,and with all the duckey's I have invested in this project and with still more to go, I don't think that I will have any left on the table for a Dyno session.
So I would like to hear some estimates on where You think the HP will be at.
I know it will be a rough guestimate, But some where in the ballpark will be better than outside the fence!
Allrighty then here are the specs.
489 c.i.d. BBC Full roller motor.
.030" over bore
Scatt 4340 forged crank, 4.25" stroke
Splayed main caps /w ARP main studs
Eagle, 6.135" forged H beam rod's
SRP forged pistons/17cc dome volume
Block has been zero decked
Bullet Racing Cams solid roller cam
Morel pressure fed solid roller lifters
Cloyes hexadjust double roller timming set
AFR 325cc aluminum heads/116cc chamber/ ARP head studs
(Head specs and flow chart. http://www.airflowresearch.com/bbc-325cc-c-1_97.html)
Crane gold rockers,1.8 int.,1.7 ex
Edelbrock TR2 tunnelram
two 600 cfm holley carbs
As good as the heads are I had a little more done to them. A little more port work to smooth out a couple bumps and a little shave to get a little more compretion. 10.29-35:1, not sure where the heah mill puts the chamber size?
I also ordered the AFR intake gaskets which match the head's intake ports much better than the felpro and the intake has been portmatched to the head's.
Here is the Cam card with all the cam specs .
So please give Me You'r best estimates....Hal
Here are a few pics of the Mill before the heads and intake were asymbled.
