Are the aluminum Magnum Mopar Performance sold cylinder heads too rare to find?
Seems like I remember Larry Shepard writing they were “about” 52 cc combustion chambers and the deck could be milled a lot.
Didn’t Ebogger find some aluminum MP Magnum cyl heads for the Magnum 5.9 V8 he transplanted into a v6 Dakota?
Long ago we had a Mopars thread about whether aluminum heads affected either max hp or max bsfc, my reading of what reliable data there was led to concluding no measurable differences.
Mazda’s 14 to 1 engine used aluminum heads.
On a 5.2 Magnum I would stay below 12.7 static cr
Are there any production 4” inch steel pistons out there for industrial engines, like natural gas or 2 stroke heavy bunker oil?
Yes I would love to find a pair of the aluminum magnums or eddelbrocks or heck even one of the iron EQ, R/T, RHS... to use as they all have a much larger pushrod pinch that keeps the fuel injector from spraying on the side of the port. I can't find my old notes but I do seem to remember they all had smaller chambers than the stock head, even the chinese crap has a smaller chamber but even worse PR pinch. I just can't find any and when I do find them they are very expensive.
