[QUOTE="Klaus, post: 16672982, member: 190070"] Get meth and stick to factory CR. Because: You are fuel limited as long as you stick to 91. It is a lot easier to swap a pulley than it is a piston. 8.6:1 is fine. This is what the 5.4 CJs ran FWIW. Also, I would stick to a smaller blower. A gen3 or 3.xx KB is going to be lazy at the boost levels that you will be required to run given that you are sticking to 91. A ported TVS/Gen IIr/Whipple V 3.0 will be fine and will hit much harder down low. I ran both a gen IIr and a Gen III on pump gas and the Gen II was better for the application. Those setups tapped out at 680 whp and 660 whp on 91 w/ FBO to give you an idea. You will get a bit more from cams but not much. I beams are not necessary for your application. H beams are fine. Get a Big Un IC. ID 1050s are probably fine although 1300 will give you room if you ever switch to E. You do not need return fuel system is you are sticking with pump. Do it if you are switching to E. Switch to terminator timing gear. LOL you do not need a billet crank. Stock is fine. Get it keyed. McLeod twin disk while you are at it. [/QUOTE]
