383 Idea
IF DOING A REBUILD.....WHAT ALL IS CHANGED WHEN TAKING A 35O UP TO A 383? IS IT JUST THE CRANK AND RODS??? SAME PISTONS AND EVERYTHING ELSE?

When the 383's first became popular(several yrs back), there were several kits out that used a 400sb crank with the mains ground undersized to fit the 350 block(approx .200). They also used the shorter 400 sb rod combined with a stock 350 piston,& while everything fit,& pretty much cleared the block, the shorter rod caused heavier side loads on the pistons/cylinders(more friction & wear). With all the aftermarket parts available now, its better to run a 5.7 or 6 " long rod & an aftermarket piston. there are also many aftermarket cranks avilable to drop right in the 350 block (for about the same cash as a reground 400 crank). This does require a little clearancing in the block, & on the rods for cam clearance as BigJim mentioned...but straightens up the rod angles, & gets you a freer running/ longer living 383 (also higher revving....& we all like that
