Just be sure and go thick enough to do your motor justice. How bad/thin are your current cylinders? 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Just be sure and go thick enough to do your motor justice. Call Darton and see what they have for your motor. I'm not sure if they offer both steel and ductile iron sleeves for your deal but if they do get the ductile iron sleeve Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

No issue with head gaskets. In fact its gone quicker than before it was fixed. It has50 passes so far. No water leaks, it has good power. Ive been pleased with it. Price 8 Darton sleeves and labor. Ouch. Fix what is necesary and move on. Doug

No clue of how many runs as I bought the engine used and took it from 4.530 to 4.560. No sealing problems . Really not 100% sure what came first. There was a failed lifter stuck in the bore with a few needles sticking out. That valve was hit by the piston. Rod was bent and bearing was damaged. Sleeve cracked. I was turning the motor a little over 8 grand. Car was too heavy for a glide and had 4.56 gears in it back then to get it to launch. Thinking I want the hemi back in the car. I will grow it to at least 572 and probably go with a pair of 4150 style carbs on a tunnel ram. here was one of the last time slips.

It spun a bearing. Probably made it through at least 2 passes after the damage started before it broke. My fault I knew something was wrong at kept running it. It has Molnar stuff in it again. Doug
