It's a GM Mk IV 7.4 Liter with a cracked block - A certain carburated GM 502 is going to appear here tomorrow. I have a week to evaluate it. The guy smashed the OMC King Kobra completely off the 502 boat. Two of his pals tied a-beam either side, and helped bail and towed him back - Water in the boat was 'bout up to the valve covers. A week later, the boat's in a 'friend's shop, he goes and fires the engine. Lights off and runs, life is good. 3 days after that, he goes back, lights it off, gets a huge ass-end crash, w/cracked bellhousing, motor jams and stops... I'm thinkin' the starter crash just made the engine cheaper, as I don't think I need his flywheel, bellhousing, or starter, and know I don't need the coupler, as I got Bravo1 with all that. Let's say they are both Mk IVs - Do I have to get a balanced flywheel for the 502 if it's scragged, or can I bolt my 7.4 L right up? I worry because they are externally balanced cranks, and I'm a flatheaded
rookie.
