Got a few questions for those veterans that have done these things.
Will a 273 crank (forged) fit in a 318 no problem?
Yes
Connecting rods on a 73 318, are they full floating type? Read that some are and some arent, anyway to tell besides tearing down the engine?
I do believe there floating. The only way to see is is ether take the engine apart or take the oil pan off and look up when a piston is at BDC. Neither is fun if you just want to know and go.
Magnum heads, are they aluminum or iron? Read that some arent and some are (Haha) and what kind of cars/trucks did the aluminum come on?
Stock Magnum heads are iron with the MPP being both. Look for them in trucks. (Iron versions.)
Also again, I read that magnum stock exhaust manifolds flow better on the driver side but not on the passenger side, compared to the 340HP. Could you put a magnum exhaust manifold on the driver side and a 340HP on the passenger side?
Yes, this is suggested in the engines book by MoPar Performance.
Just curious to these things. Also some place that sells the Magnum aluminum heads would be great!
