I've just pulled a 383 apart for a freshen up. Scary to say the least. Rod ratio 1.52:1 . Crank hitting the main web. Std Main bolts. Mexican (literaly) cast pistons, weird looking conrods , COME crank- not a lot of evidence of balancing, i will have to run up the assembly in the balincing machine to check.King bearings- not the high performance ones. Sump has half the bolts missing as the pan rail area has been welded up in places so that clearencing for the rods could happen. Seems like a lot of work and a lot of stress on the block for what gain (above a 355) i'm not sure.
Anyone got anything I should be aware of with a 383?
Cheers
Bin it and get a big block 202.
