Just thought I would make a thread to update my status on my 1992 f350 crew cab gas to idi conversion. First the gas 460 ran great just 9mpg really sucked for me. I had a 1988 f250 with a 7.3 and a 5 speed. Was a decent truck the blue one I had on here for sale awhile back. So I pulled the engine trans and radiator from the 88. First I was just going to reveal everything and put it in truck was running good got 16 mpg. Then I took the motor apart just to inspect it so I wouldn't have any troubles later. Found the rings wore out bore was ok just some taper 0.003. We'll since I'm so lucky I got a 88 7.3 which no one makes a oil ring for the pistons. So took the motor to machine shop, bare block anyway. Block is still there waiting to be bored 0.030. Got a set of Mahle 0.020 shorter pistons with the hard anodized coating, only had them in 0.030 over. New Mahle rings, new cam bearings and freeze plugs. I sent the cam to Delta Camshaft in Washington state had it reground end to their 206 profile. It's back waiting on block. I worked on the heads for several hours porting them. Got all the casting ruff ness out and worked the bowl and valve guide area. New comp 910 springs to go in it. Got all new valves std size. Going with a 3 angle valve job. My arp head stud kit came in today, the bolts I ordered from compition products products was wrong why the price was so cheap. They sent 7/16 bolts and light duty 1/2 nuts! So I should have a good bottom end.
