ok machine shop question

[ramz28]

OK im going to get my 351 and go to a machine shop. im going to dissassemble the motor myself, down to a brea block no pistons, rods, crank ,cam nothing just the block.
I want to go to a machin shop and have them bore and stroke to a 393, is there anything i need for them other then the block? how much does this usualy cost? should i let them buy the stroker kit? helpp anyone

Wouldn't the rotating assembly have to be balanced?

Yeah you would have to have them bore it, new cam bearings balance the rotating assembly, and I would have them put it in the block too. I had them do that for my motor and found out the rods had to be clearenced. I would have never known that. For them to balance it they will need the rotating assembly and flexplate or flywheel and the balancer. Also see if they can buy the rotating assembly because they might have a guy that they deal with that sells good ****. But it is up to you.

For my 393, I had the shop bore it .040, you could probably get away with a .030 bore. The cubes come from the 3.85 stroke crank. I used 302 pistons for the wrist pin location. If you decide to build it yourself, get ready for alot of work, mainly from grinding the crank for .050 clearance between the block and crank. In the end you'll have to have everything balanced; crank, rods+pistons, balancer and flywheel.

ok just got off the phone with 2 shops 1 in LI and 1 in NJ
they both said all they will need is a stroker kit and a bare block, they said it will be about 600 bux and then ill have to reassemble it on my own.. i hope this is good a couple of friends reccomended the shop in LI and he 50 bux cheaper so i guess as soon as im done with my tear apart ill go there and have it done.
