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.
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.
