Sweet! Standard bore? Should compliment the cam you picked and pump gas nicely.
Apologies up front, but here comes the
// Poindexter=On
I spent some time looking at pistons a few weeks ago, and those were high on the list. They have the right compression height, good call! Then I remembered I'm on a budget and thinking if I go that far, I'd bore it, and if I went that far, I'd stroke it, and then I said (something) it and started looking at gaskets. lol.
While in Excel splitting hairs, I saw that Cometic offers a great looking on paper MLS gasket, too bad they cost over half what the original engine did. 4.400 bore, .036 compressed, worth another tenth or two CR over the rebuilder Felpro best case gasket. C5666-036, and best case came up with 9.72:1 with .002 deck, roughly 9.4 with the worth case Felpro rebuilder gasket.. Kind of shocking you can have a .3 CR spread with two sort of similar sized "on paper" gaskets.
I'm still considering having the heads cut .025 or so because I can't personally justify throwing down 90 bucks per gasket to blueprint a .038 quench in a budget build. I'll tell ya though, I'm struggling with budget versus throwing all that out the window and TFS head a 521 and PimpXShift that thing.. lol. Back in the I'm lucky to be getting away with the budget I have world, I looked at the 1.772 pistons for the Lincoln block wondering if they would stick out the hole? I'm not afraid of a thicker gasket to get that .038 quench I'm stuck on.
// Poindexter=Off
Short version: I'd guess right at 9.6:1 from my armchair and 125 off makes them a pretty decent deal!
