Pete, The new AFR 235's flow extremely well (340+ CFM in the mid .700's....330+ in the mid .600's). They are well over 300 CFM as early as .500 lift which is insane. This a a non raised runner 23' head with a 1206 opening and it swaps in place just as easy as our 227 (same geometry, valve, and stud location). Im really excited to see its power potential and might be building a 460 CID smallblock (with a Dart Little M block) that I may feature those heads on. Its going to be a low compression build (9.5 CR) with a mild for its size hydraulic roller (in the 248 range at .050). Its going in a boat hence the low compression but this build could easily be copied or used as a suggested starting point for something more aggressive in a street car (I would add 10 degrees to the cam and a point of compression for starters). Im hoping for 600 ft/lbs and 600 HP by 5700 RPM's or so (TQ peak likley around 4300 ish). Obviously with big area under the curve (450+ ft/lbs @ 2800). Should be pretty interesting....the more aggressive builds with these heads should easily clear 700 HP....725-750 in a well built high compression engine. Keep tabs on this product....we should be releasing it around March of 09' -Tony |
