Big Hp looking at 1200hp And up, on conv head 460 based block

Sorry for taking so long to get back.The A 460 Heads were brought up last Real Street Meeting And Were Not Allowed,Also The GV2 Headed Windsor Motor I Have Flows 440 on intake.Thats On Kuntz's Flow Bench.Makes Over 900hp But still not enough weight difference to overcome the BBC.And being the only SB in class its hard to get the big blocks to add weight (Rule Change) Thats why im trying to get as much info on the BBF,I have Raced a 572BBF in my altred

im guessing the guys throwing out the big numbers on there flow and horespower are full of it. if the a heads not allowed then you might get a set of the boss heads in there theyd flow great but not anywhere near the air those guys are telling you. if not you might be able to do alot of work to some of the scj heads or p-51s with some work they might sduprise you on a 600 inch motor with the right cam. brad

When you guys say A head and C head, what do you mean? D0VE-C, D0VE-A?

A HEAD= A460 MOTORSPORT FORD HEAD

C HEAD= C460 MOTORSPORT HEAD

don't give a crap if he does or not cuz if it takes 520 cfm to make it in the Class well that shoots the TFS A460 head way out of the water... the A heads around here are conservative maybe around 460cfm or so

I got A460 heads from Steve Vance and they flow 490 at .850 lift.

Duh, it was right in front of my face how did I not catch on to that.

I would like to know how they can call a head that flows 520 cfm a conventional bbc head?

IDT makes an A head that flows 520 cfm , but it's a far cry from a conventional head.

Nor is a Thor or a Profiler both above 500 CFM.

I guess the bbc head design is so superior to the BBF head it's easy to get those big flow numbers out of them with out getting away from the stock lay out

No I doubt it, they probably do flow that............. Just another screwing the ford guys are getting.

The best flowing conventional head we have other than the boss head is a P-51 Kasse.

Is there another conventional head for a Chevy, that could get to that potential?

Something we (I) are not aware of ?

Maybe the mystery engine head they used in Nascar................

Well, looks like your best bet would be the P51's, unless you have the money and time to go with Boss 9's. You could get over a 1000 probably with either of them at 640 cubes, but it would be easier (and more $) with the hemi heads.

Please let us know about those chebby heads, just to cure the curiosity.

Yup, I think it would be interesting to hear what conventional chevy head flows thoes numbers.

John Kyle at Apd gets over 500 cfm out of the brodix Head-hunter head With ti valves etc.

Guys, remember it is not always about flow numbers. Where does it make power, What is the average power, How much power on the shift, how tight can I run the convertor, what are the flow numbers at 6 and 700.

Years ago we picked up my a-heads 20 numbers at peak and all I seen was a little mph and a loss in 60, 330.

Coug I understand what you are saying but Lawes and Charlie are consistently in the upper 470 and low 480's with stainless 2.350 stainless valve. My a-heads are in the 490's and a few bust 500 but not without 30 hrs of work after normal port job and combustion chamber work.

All I am trying to say is do not underestimate the A-head and its ability to produce. I beleive we are just beginning to see what the p-51 can make happen. It is going to take several guys that are capable of tuning an engine and can give good feedback to actually know what these heads can produce.
