I'm swapping 440 blocks from my cracked original to a '77 motorhome block. The block was virgin bore/deck, already at the machine shop, line honed, magnafluxed, and bored to .020 for a customer that went to jail and sold the block for the bill. I had the bore upped to my .040 over and decked for Cometics. As I was reassembling it last night, I got the inkling that I shouldn't put my main studs in since it wasn't line-honed with them. I'm running a 496 stroker that makes right at 600HP, and now am at a quandary as to the best path forward.
-50 year old stock bolts (factory torque spec, 85ft/lb?)
-New ARP bolts, (110 ft/lb spec)
-Run the studs. (110 ft/lb spec)
I have all 3 options/fasteners in hand. I know swapping to studs is frowned upon without a fresh line-hone. Remachining is not an option. No time left. Rocky Mountain race week 2.0 is in 2.5 weeks.
What is the least evil option?
