500 plus cfm A460 HEADS

Post  studly on January 11th 2012, 11:19 pm

Alright whats the max flow you have gotten out of Trick Flow A460 head ? Who has the best program for them, My father has a set on his 638, and i need somebody to help this set out. already has Tit valves, have to check the sizes. but who is the best to do the heads and a single dominator cast intake.

how much Bling bling is this going to take to make these heads preform on this motor. right now it made about 1060hp and over 900torque max rpm right now is 7800rpms would like to open the power range up some. looking to go up to about 1200 hp can it be done?

Studly,

We're right in there with a CNC porting program and then additional hand work clean-up for intake flow of 470+ cfm. A couple of varibles are; intake valve size and the valve seat angle.(i.e. 45*, 50*. 52*, 55*).

On the exhaust we're always around 325 cfm without a test pipe. Pipe numbers will be 25 to 30 cfm more.

Hope this helps,
Charlie

I will check on the valve sizes he has this motor has been together for about 2 years but only has probably 15 passes on it. how much to CNC the head and some hand work to help smooth out the edges. this is a NA motor about 15.1 compression Eliminator block, scat billet crank, and MGP rods with Ross pistons and Hellfire rings. it has a quick fuel 1450 single carb. I think the intake needs some serious work also. thanks for the reply

Replace all the seats, use a 2.425" intake and 1.840" exhaust valves with 50 degree seats and a good "A" head WILL provide over 500 cfm intake air flow; (been there).
All the work required will usually cost as much or more than a better head to begin with. However, there are sometimes class rules which make it necessary to use an "A" head ... you then need to do whatever you have to do in those cases.

What about angle milling the cylinder heads for increasing flow

Angle milling doesn't add much to the airflow however, it does lessen the chamber cc's the most with the least amount of metal removed.

I agree with Rich, why not just step up to some C460's or Profilers.

Phllip did 1200 with a single 4 with C460 heads on a 645" motor.

Sell the A460 stuff and step up.

#1 he asked about his existing TFS castings and 1200hp - current best seen on here is 1123 with a single 4 with the TFS heads, Not a bunch of the other modern A's that people are sharing dyno info on.

#2 To go with those A460 (They are damn Nice Stuff and I like them too) it is expensive over reusing his current A's, for the $$ might as well step up to C460 (They will do well over 511 cfm nowdays) or Profiler A205 (The will get you well over 550 cfm)

#3 Other things to consider, Valve train Life and additional requirements trying to get the A460 heads to 1200hp, the bigger heads (C460 & A205's)should get their with a smaller cam. You don't need 1" + lift with the higher flowing heads to reach the desired number.
