Which aluminum cylinder heads will work best on a 440 cu in, 10:1 compression, 7500 RPM pro street BBC.Eng?
I have a 440 cu in BBC all forged short blk. I will install a roller cam that is properly matched to the combo. Possibly even a 7,4 cyl swap style cam. This will be a single carb eng. I will possibly swap over to an EFI throttle body set up later when I can afford it. The pistons should yield 10:1 to 10:5:1 with a 119 cc combustion chamber. The car is heavy, 3400 LB Chevelle. Turbo 400 trans 373 gears. I plan on doing some heads up drag racing several times a year, with some friends that have comparable cars,driving it to local car shows and having fun. I can not afford a big cube eng right now,so I plan to use what I have. I am thinking of possibly using the Edelbrock or Brodix race right heads. I am afraid of using AFR as I think the ports may be to big for this small of an eng, although I would like to as I could use them later if I can afford a bigger eng. If I get this combo correct I can make 650 to 700 HP, I could ad some N20. All experienced advice is appreciated.
if your engien is a wider bore than stroke and it revs high has a fairly long rod length ratio and you intend on driving high rpms then get a head with big ports
i would say go with edelbrock but make sure you get ahead with big ports
