Guest the_dj Posted May 28, 2002 Share Posted May 28, 2002 In my continuing search for a new set of heads, a cam, and the Holley Stealth Ram (the one part I know I want), it was suggested that I consider the GM aluminum fast burn heads. Does anyone have flow numbers or comments on them? What kind of power could be made from the fastburns and a good (quite healthy) cam using my current modified TPI intake with high flow runners? How much more would be picked up when I switched from the TPI to the Stealth Ram. In the end, I'm still looking for power levels approaching 500hp.

Tim240z Posted May 28, 2002 Share Posted May 28, 2002 Check out Scoggin Dickey's web site. They have the flow numbers in their printed catalogue, but I don't have that with me, but I'm sure that they would have some numbers on their site, or if you call them they can tell you. But if I remember correctly, they don't flow that well, and you would be better off with some Canfields or AFRs, or Victor Jrs. Tim Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted May 28, 2002 Share Posted May 28, 2002 first the G.M. fastburn heads don,t fit the stealth ram intake ports,(they have vortec style ports) yes you could port the intake and have some welding done and get it to work but the fast burn heads don,t flow the numbers they show (out of the box either) the flow numbers were taken from a mildly reworked set of heads. your far better off getting AFR,195cc or 210cc head or CANFIELD 223cc heads or some other good flowing 23deg sbc head if your looking for 500hp, and don,t forget your going to need a serious roller cam in the area of 245degs@.050 lift to get 500hp, my roller Im useing, falls at least 20hp short of 500hp and thats with ported heads http://dab7.cranecams.com/SpecCard/DisplayCatalogCard.asp?PN=119661&B1=Display+Card something like this cam will be better but remember hp is not what I was after , I was after a wide torque curve from 2000rpm-6000rpm http://www.compcams.com/information/search/CamDetails.asp?PartNumber=12-772-8 match this cam to the AFR 210cc heads and the stealth ram with 32lb injectors on a 383 with11.5 cpr and youll easily exceed that 500hp.
