Heres is my current build so far, the shortblock- 1971 318 block bored .030" over stock crank polished and balanced 340 floating rods 340 windage tray Federal Mogul STL-285NP30 pistons, sitting at zero deck. Crane powermax .454"/.480 lift cam. I need help picking what heads and intake I should use? Thanks for any suggestions! I have a set of #587 340/350 heads w/ 1.88 intake valves and gasket-match porting, these a freshly rebuilt with a 3-angle valve job. And I have a stock set of 318 #302 casting heads that need rebuilt. 1972 Power Wagon W100 1973 Power Wagon W200 1971 Duster 1972 Dart Swinger 3-1972 Demons

Dual plane or even a performer intake for some low end. 1972 Barracuda - 5.7L Hemi, T56 Magnum 6spd - https://www.facebook.com/GoodysGotaHemi 2020 RAM 1500 [img]https://i.imgur.com/v9yezP9.jpg[/img]

And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
