Some of you may know I recently went on a search for a 350 for my jeep. First i got fouled into getting this crap ford motor (turned out to be a turd) well, i since got a chvy 350 and have been stocking tools and working the block. it's a one piece rear seal basic 2 bolt cast. i had it checked out and started purchasing pistons rings blah, blah, blah. my problem is, is i never done this before (thats first). i cant get the wrist pins out of the connecting rods to put on my new pistons on the old rods. i dont want to beat on the thing, i tried expanding the upper rod bore w/ heat didnt free the pin? my rebuild book and the new pistons say to do the procedure by hand and stirctly say to avoid a using a press so what gives? just keep w/ the heat? but dang it was glowin' dam near. (i was also afraid the heat might warp the rod...?)any help would be great. other than that i've finished rebuilding one head, started the other. tapped every bolt hole on every component. honed bores, tanked and painted the block (red) no fancy heads just 76cc cast (charcoal grey) next month is the intake. i will be gear drive instead of chain but other than that pretty much stock. less a mid class carb. im not tryin' to go "balls out" on this build but do want a good motor when im done.
