My 1st 5.9 Magnum Build

70aarcuda said
Last summer bought a complete 97 5.9 Magnum for 150. Came out of a Durango with 140K miles. Had a problem with intake plenum leaking oil. Torn it down, and the cylinders looked great. Used a flex hone and honed the cylinders. Clean pistons...rods and block with oven cleaner....crank look good...put it all back together with new rings and bearings. New oil pump...pan and pickup. Stock roller cam and lifters. Heads are rebuild Magnum heads from Ebay. Have not put intake or front of cover on since I dont know where it is going yet, either 88 Dodge D250 or 94 Dodge 2500.

Got another Magnum in the works. Have set of IMM EQ heads for it...

I'm putting a "hotter" top end on mine (ported Eddys, custom-grind cam) yet you did more prep to the bottom end lol... It probably would have been a good idea to flex hone and re-ring mine but I'm not comfortable doing that and there's still about 70% of the factory crosshatching left with zero ridge at the top. Did put in new rod bearings though (the uppers had a decent bit of copper showing), also swapped over the oil pump, pickup and pan (stock car 360 with welded-in baffle) from my old 360 that only had 25k or so miles on it when it broke a piston.

You should post a video when it's up and running...
