Hello, I am new here. I need help from Hemi builder or expert. I would like buy a new Hemi Block from Mopar Performance #P5160151AC (rough bored 4.24“). I would engine is for Street Performance (no Strip etc.) Stock 68 Coronet R/T, 4 Speed 18 Spline A833, 3.54 Dana S60, 295/50R15 on rear. I would build engine with: -Rotation Assembly from Indy (472 with 10:1) -MP Iron or Alu Heads or Edelbrock Victor (ported minimal only gasket area) -Intake 4x2bbl, I dont know what better, I think take MP or mod man from Indy) -Rockers Assy: Mancini Racing (it is good?) -Camshaft, what should take? I think take Hydraulic flat tappet -Oil Pan maybe Milidon -and other parts should all stock. I need your help, what is good setup? Other proposal? I think I would like habe about 550 to 600 horsepower. But torque should good and high too. Important question: I cannot find information about MP (iron/Alu) heads. How much can max. lift of valve springs? By edelbrock victor can to .700“ lift. Have anyone sell of Valve Covers (Black or MP Alu) and Air cleaner Assy (for 1970)?
