    AFR website

     



    Has any one looked at the Air Flow Research website.
    One of there dyno figures shows 465hp with 180cc heads, 9:1 comp,
    .480 lift flat tappet hydraulic 230 @ .050. .
    Not sure but that seems alot of power for this combo or is it just me.
    Any thoughts please.
    I build engines for a living. The last 383 i done had 195 AFR CNC ported heads, 10:5:1, 507/510 lift hydraulic cam thats what he wanted i reccomended something around .550 lift with the comp it had. air gap , BG Mighty demon, balanced thats why i raise this question of 465hp
    It only made 420 hp at 5800

    I've never used any of AFR"S heads except the Ford twisted wedge and matching intake.... Built a 408 Windsor stroker, my dyno results on 3 passes were within 5% of what AFR said it would be..... Guess I'd go with their recomendations on a Chevy too... They've got the R&D time and the dyno results to back it up......

    What was the duration at .050 of your cam with 507/510 lift?

    I built my 383 using AFR 190 heads, CompCams Magnum 280 cam (it has the specs AFR listed), 10.6:1 static compression, Edelbrock RPM intake with an Edelbrock 750 carb. It was dyno tested on a Staska dyno, and it made 450 hp @5700 rpm and 468 ft. lbs. of torque at 4300 rpm. Given there is up to 5 per cent difference between dynos, I would say that those numbers are correct.
