New AFR heads

Post  738drvr on January 7th 2015, 3:52 pm

Just got off the phone with AFR. Here's the latest:

Should be able to order by the end of the month. 3-4 week build time.

Price:

270cc with stock exhaust ports 2170/pair assembled for solid cam up to .850 lift.

285cc with exhaust raised .250 2799/pair assembled for solid cam up to .850 lift.

300cc with exhaust raised .625 are not finalized yet.

Single plane 4150 intake is 319.00.

Dual plane and 4500 intake to follow this year.

Test mule for the 270 and 285 head was a Ford Racing 521. Slightly better than 11:1 compression. Cam was over .700 lift and over 270 duration at .050. Both heads made over 700HP.

285cc head flows 320's@.400 and 411@.700 intake, 285@.700 exhaust.

You will have to flycut your pistons until the manufacturers catch up. AFR has sent there specs. to all the major piston makers.

I want a set NOW!
