I'm hoping it goes well for you sir. Even with all of the great guys here to help me along, there's just so much to consider. I just got a kit from 440 source that arrived just today. But my machinist has had the block for 2 weeks. I've never done a kit like this before and it was very confusing to get an agreement between my machinist and 440 source Mike and Terry. I had an interesting talk with my machinist. If I have him mill the deck to just be clean only - He will cut it however the deck sits now - square? unsquared? He can't say until he gets the kit. He squares decks after the bore sizing is done by setting all four corner pistons to get a "read" for squaring the deck. because my machinists tools/machines are on the older side of things compared to modern computerized machines. Things were done differently then; as compared to now. So, I'm gonna wait till I see what the new piston height comes out to be before I have anything done to the deck. I ordered 10.00 pistons which both Terry and Mike say that means 10-1 with an 84cc head chamber. I'm hoping it will only need to be cleaned up a little - like 3-5 thousandths - but I got no problem with running it untouched either. The deck is virgin w/no visible issues. He wants $80 to clean it - and up to $700 more to square it depending on how many passes it takes - which may make it too low for the kit I ordered. very frustrating dealing with this old timer. I can't order the kit from 440 source unless I know the bore size after the cut and hone is done - but my machinist can't hone the cylinder without having the piston there to fit it correctly to the cylinder 440 source only has certain size pistons for certain size bores with certain size chamber heads. You cant just order a 10-1 pistion for a 4.375 bore unless you have the right heads for that particular kit. 440 source might not have a 10-1 piston for a 4.330 piston at 30 over to fit my heads. I might have to go .55 over to get a piston kit from 440 source that'll fit my head. Or what ever it may be. And there's no returns if the bore is wrong. I'll have to pay to have it bored out larger again and have to pay 440 source another $3000 for a different kit. My machinist can't simply go from 20 over to 30 over he'd have to go to 40 over but 440 source might not have a piston for 40 over. BLAH BLAH BLAH. If I buy a scat kit from my machinist - he'll make it right if he's wrong about where the final bore might end up at and exchange the pistons at his cost. But that costs $7000 and I still have to put it all together. $10,000 if he assembles it and ZERO warranty anyway I look at it. It shouldn't be so complicated. I feel like no one can man up and take responsibility for their words between those 2 companies.
