Full CNC Ported (C. Evans) New Style TFS A460's average of all 8 ports.

28" H2O, No Exhaust Pipe, on a 4.625 bore, 2.35 Rev SS Intake, 1.88 Ferrea SS Exhaust, Flowed on a SF600 Bench

Intakes / Exhaust

.100 74 / 58
.200 161 / 118
.300 245 / 165
.400 315 / 200
.500 375 / 235
.600 408 / 267
.700 439 / 294
.750 451 / 303
.800 465 / 312

The exhaust flows are low due to a couple of ridges and I'll post the revised flows later.

Re: A460 BBF Head Flow

In its current trim at 12.2:1 and 528" is making about 905 and 725ft/lb. The heads are a little on the large side for the current build. I had the heads CNC'd and it opend the chambers up a bit and lowered my compression for the intentions of upgrading later.

I intend to open it up to a 572" and put some compression to it, Should go up to about 1025-1050 with a single 4.

How big was your BBC? Sounds like a nice build.

Re: A460 BBF Head Flow

With less CFM head flow than you showed here, I had a BB Chevy make 1070 HP with one carb, and 1225 with two carbs, What are you shooting for with your engine ??

That is a great deal on those SCJ's.......They will do 370-380cfm with a modest amount of blending And bowl work. 650HP is easy and a 557 is the same price as a 501....LOL Use the Force Paul !!!
Well I think I'm going to stay with the rebel forces. I'd like to get Jim Kuntz to port some Edelbrock Pro Port FE heads for me. Then I'd bump my compression to 11:1 or so, put in a 255-260'ish solid roller, and a ported Victor intake. I think I'd have 650 hp or so. The tradeoff vs. the 460 will be rpm and cost. I'll probably change my mind again next week.

Then I could start assembling a 466 or a 501. The low price is freaking me out. I'd only be looking for 650 hp or so. Nothing like yours. This would be for my street car.

I'm really struggling with this as there are now aftermarket FE heads that can flow around 400 cfm. Of course the price would be higher and the motor smaller if I stayed FE.

What a dilema.
