newer isnt neccesarily better... actually some of those LA magnum heads like to crack exhaust valve seats in those "modern" heads.
a steel crank 383 at 13:1 on E85 with eddy heads, E85 quickfuel carb and a .528 mopar cam would seriously blow that 360 out of the water.
you would need to do some serious work to the magnum to get at the same level, costing way more and even then it would not be as long-lived.
13:1...??? Aluminum heads...??? Dude... you just built me a $5000 engine. A running 383 or 360 Magnum (that doesn't need a rebuild) will run me less than $500. I can sell my 383 to buy a 360 Mag, so essentially free for me. NOBODY is building an engine here.
STOCK 383 + bolt ons vs STOCK 360Mag + (same) bolt ons.
