1hirschdalemopar OP member 1 Joined: Feb 2009 Posts: 54 ca,us	I am wondering how much you can take the deck down on a 440 block before you have to start machining the intake,I am running the performer rpm with the rpm heads And I want to use the 440source stroker kit, 4.250 crank,7.100 rods,17cc dish 1.480 c.d. pistons which leaves the pistons .015 down in the hole and gives me 10.05 to 1 with the 84cc heads with the .039 head gasket and a .054 quench.I am wanting close to a .040 quench and 10.50 to 1 comp.So I need to either bring the deck down or order custom pistons,so thats why I am asking.Thanks guys superbee

FWIW the OE deck surface often isn't quite where it should be, the spec is 10.725 but often it will be much higher, mine were 10.74X & varied at all four corners... So rather than request a certian # be removed the better approach is to request a # from the crank centerline.. And the # I used was 10.705...

Mill the head deck to get quench then set the heads/head gaskets on the decks and mockup the intake w valley pan and check the head/intake intake port(s) alignment w valley pan then either mill the head intake face or the intake for a perfect fit/port alignment. For either of these 2 checks fyi the head gasket only compresses a couple of thou so mock it up & see where you're at. live every 24 hour block of time like it's your last day on earth

Mine is still just a pile of parts... I have done trial assembly, I want to do a few more small tweaks, the car isn't painted yet anyway so.... As far as cams going flat, hydraulics will do that too... I have EDM'd lifters & have a Nitrided cam... I have cases of GM EOS & I'm looking into a Voodoo doll to hang under my hood.. I thought long & hard about a roller but the bronze distributor gear & fuel pump pushrod issues made me feel like a standard flat tappet was the better street option...

I went with the comp XS290S solid and it works well. I used a cometic 0.027" MLS head gasket to increase compression and it gives me 0.042" quench. The deck was pretty square on my block so the thinner gasket saved me the cost of machining. 1970 Road Runner 505 cid MCH CNC ported Stealth heads MP 528 camshaft 4 speed GV overdrive 11.98 @ 117 on street treads

Mine & yours are very similar, 440 Source kit, I had the machine shop check everything throughly & they found no real issues, the rear main seal surface needed polishing & the snout to damper fit needed tweaking... I have the 17cc dish pistons, 84cc Edelbrocks, MSD Pro Billet, Performer RPM, a Holley 830DP It should be a very docile street motor but still able to scare the crap outta me...

The car weighs 3800# and it runs low 12's with 60 foot times in the 1.8's. Best to date is 12.03 @ 116. I'm working on the 60 foot times but it's not easy with a 4 speed. 1970 Road Runner 505 cid MCH CNC ported Stealth heads MP 528 camshaft 4 speed GV overdrive 11.98 @ 117 on street treads
