grumpyvette Posted August 31, 2009 Share Posted August 31, 2009 (edited) having build a good many tpi engines I think you'll benefit from a wider 112-114 LSA and limit duration to about 215-218 intake duration example E110030K http://www.pbm-erson.com/store.php?catId=334&parent=333&grandparent=327 http://forum.grumpysperformance.com/viewtopic.php?f=55&t=1509 the main reason is that the factory sensors that control the fuel/air ratios don,t work well with reversion pulses in the intake that ,overlap in the cam lobes timing can cause ,increased duration, and tighter lsa angles tends to increase the overlap and cause problems with the stock tuning cpu Edited August 31, 2009 by grumpyvette Quote Link to comment Share on other sites More sharing options...
Pyro Posted August 31, 2009 Share Posted August 31, 2009 That cam would work well with a 4 bbl intake and holley. Your manual trans is a plus for that cam (no stock converter). I would use a more mild efi cam from compcams. Like 206 to 212 on the intake at 0.050" and 6 to 10 degrees more on the the exhaust (compared to the intake) then use 114 LSA with efi. If you really want to make more power, then swap over to vortec heads and intake. Should pick up 50hp with that swap. Then maybe another 30 or 40 with a mild cam and exhaust swap. 300hp is with in reach. Quote Link to comment Share on other sites More sharing options...
