Horsepower and torque for this engine?

Horsepower and torque for this engine? - 08/08/11 05:19 PM

451 with 11 to 1 cr using Ross pistons, good rods, fresh cut 440 crank

Don't want more compression so I can run pump fuel on street when I have to.

Ported Indy SR heads flowed with exh extension (not Max Wedge)
.200 155, 110
.300 225, 165
.400 280, 210
.500 315, 240
.600 345, 265
.700 350, 275

Victor 4150 intake and Quick Fuel 1050 4150 carb

Solid roller oval track lobes
290, 292 @.020
258, 260 @.050
178, 181 @.200
.664"(1.6), .631" (1.5)
110 LSA

2 inch Hooker headers for B-E body

What would you expect this to make for hp and torque?

560 to 590 HP at or near 6000 RPM and similar torque on pump gas

Cab - You and I must not be looking at the same specs. I'm thinking 640-660 HP at 6600, but not sure where the torque would fall... maybe 560-580 around 5400?

Brad, look at the head flow, his SR heads are 440 size ports, not M.W. I hope he dyno tests it and post the results EDITED OOPS, my bad I was looking at the exhaust side thinking it was the intake side , Brad is probally a lot closer than I am on this one

I agree on the 650 + range. This a great combo, should make good power.

I don't know how anybody can predict anything without some kind of cam specs. If you have a cam with 270* duration @ 0.050 with lift around .650" - .700", I would say it should make 630HP - 590TQ.

The cam specs are under the intake and carb specs

I'll guess 630 hp @ 6,300 RPM?

I hope, and thanks. I was thinking of going bigger on the cam, but the guy who specd it out made sense on why he recommended that one.

No dyno time for this one since I spent all my money on the parts.
