its a 5 port (or so they say), and knowing GPMD, they are going to jack up the price on it and try to make a killing off of it.

is that mid block or normal block? looks nice...but will probably be all sorts of high priced lol

big block

Old thread, and sorry to revive it.. I have a question for those that have run it though.. I had a problem with mine wearing the brass bushing on the conecting rod, crankshaft side.. Also when I tore it down I measured the crank pin, it had .0055" roundness, and .011" taper from rear shoulder to edge of pin.

OS wouldn't give me any info weather it was okay or not.. I know it is bad. But curious if anyone else has run into this problem, and what all has been done, if anything, to fix it..

pull the piston and rod out and check the bearings and see if there is any play. This isnt common on these engines. How much fuel has been ran through it?
