Alright guys I'm bringing this 440 over to the machine shop. My machine shop is recommending wiseco pistons, and the owner (Joe) said he will give them to me at his cost which is just over 500 with rings. These pistons have a compression height of 2.05 inches. Am I going to have to have the block decked excessively to get zero deck? Most of the KB pistons are more like 2.06 compression height. And I know when you mill the heads you need to mill the intake surface to correct the geometry, is anything required with milling of the deck? Or does it not effect geometry? Also, whats the preference for aftermarket H beams, eagle or scat? They are priced about the same. I always thought Eagle was a better brand. Other than that here's the gist of my build, throw any comments in! 1968 440, .030 over Wiseco flat tops with valve reliefs of 6cc, 2.05 compression distance Eagle or Scat H beam rods Stock forged crank, turned .010 undersized Clevite 77 tri-metal rod and main bearings, with the mains being full grooved high volume oil pump 440 Source Stealth Heads. I would do E brocks but I really prefer the stockish look and the straight plugs. Upgraded locks and retainers are in the plan. Old TM7 tarantula intake DC509 cam, the old one with the 108 LSA Erson ductile iron rockers Hooker Competition headers 800 Double Pumper The car is a '67 Satellite, 727 with ~3000 stall and 4.10s with L60s. The car is really just a street car but will see some strip action just to get a time slip. I'm hoping for 11.80s once the suspension is sorted out.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Hands down go with Scat rods. Actually stock rods with bolts will do just fine for this power level. The difference in comp. ht. is only .010. I would mock it up, then determine if you can run a thinner cometic head gasket. They make them from .017 thick and up.
Are you using a good oil pan? You'll need it with an HV pump. Full groove bearings are not neccessary for this build. 1/2 or 3/4 groove will do. We usually mill the intake manifold to keep the valve cover rail as thick as possible because they are pretty thin as is.

If you want zero deck with those pistons and rods, he's probably going to have to mill your deck about .025", give or take a little for block squareness and casting tolerances. Nothing to worry about IMO.
Seriously ??? Would you cut .025 off a head and not worry about anything ? Not cut the intake side of the head ???
I have to do some math

Well right off the bat we almost all go to a .039 fel pro composition gasket so that puts the heads back up .017 to .018 right off the bat from stock .022 steel shims. so little change then unless you do excessive milling to the head after that nothing to worry about. That will put his true compression around 10.2 to 1 (I cc a set of stealth's last year all were 82.5 to 83.5) so with the 3000 stall you will need for the 509 should run fine on 89 91 for sure.
As said clearance the heads on the intake side for pushrod think even 5/16 will be to tight.
Degree that cam in about 103 (102 to 104) it will really wake it up. If you do not degree it they are often around 107 to 109 and you should use a 4000 stall! Even at 106 it will need a 3500 to 3800 stall. trust me I love that cam but it needs to be degreed in with some extra advance. Set the total mechanical timing to 38 all in by 1500 (i like 1200) and you should have a stout little combo!

the valley end rails need to be cut , you use the sme math as the intake side of the heads , .0123 for every .010 of the deck of the valley pan , ASSuMEing he is using that, will not sit flat. Plus he needs to check the heads to the valley end rails. On my 383 stroker build between the heads I was using , cut .050ish , and the deck cut about .025 , I had to take .070 off the valley rails to get the intake gasket to sit right .

My problem with the wisecos with the 2.06 compression height is that they don't seem to be available in a .030 over size, only .055 over.
I was actually going to inquire as to what everyone was running for an oil pan, but I figured I'd save it for another thread. I'm looking at 7 qt pans, particularly the Milodon low profile 7 quart but it says that its 7 inches deep which is the same as all of the non-low profile pans that hold 7 quarts so I'm wondering what gives.
And if the consensus is that full groove mains aren't necessary, is the high volume pump necessary?
