Engine is NIB 496 with Cast heads still on, but has aluminum heads and cam to go with same, along with Roller rockers, etc.. Supposed to put out about 425+/-. My engine is still fine, but this is tempting
No rivets on mine either just bolts.. Height is REAL MAJOR ISSUE. Have to measure engine height with heads off, and then go from there in order to figure how far up I have to get body May not be doable?? Will start some hard measurements today...

Got a plan in place to tune it? Lots of potential in a 502. The L18 was intended to be a long haul guy, not a big hill bruiser. I decided years ago that if my L18 experienced an early demise, I would look to the 502 and it's variants. Lots of options to take the Allison 1000 series to the next level or 3; the mad-power pickup crowd has paved a highway in this area.
$$$, though. Starts adding up.
Even though you mentioned early on in this thread that the swap was not imminent, I hereby motion under any and all applicable, intangible but very real, guy-codes that you be obligated to kick off a nice new thread with narrative, and pictures, of the process. The pain, the sweat, the tears, all of it. And I hereby pledge to you I shall read and appreciate such trial and tribulation, I will learn and grow from your experience, and maybe even commiserate a little recalling power train R&R activities from my past. Just a little.
Seconded?
