A B1 MC head. Moved Centerline.I'm sorry, what is that?
Sure thing, nothing crazy for sure. 281/292 @.050, .800/.765" on a 115 lobe. Standard firing order. An older cam I had lying around that seems to work well with a B1 deal. Its apart right now, going to throw some compression and a bit more modern cam at it now. No crazy spring eater or pressures.Cam specs of there not too too secret
Again, I don't have nearly the experience many in this forum section do, but that is a HUGE intake valve, 2.400" and I would say that is "race only" in that low and mid range RPM performance would suffer from lower velocity. If I understand correctly, the intake valve size of the Boss 429, being so large, along with putting pollution crap on a race motor really hurt the street performance (and "cred") of the Boss 429 back in the day.B1Mc head has a 2.400" intake valve. I have decided to stick with the originals. They are at Slawkos right now getting a tune up and new titanium valves.
Thats a lot of heat to transfer thru .043" rings. If the pistons aren't done you might want to rethink that. Either way a stainless or Hellfire piston ring.Thanks, we'll get there. The additional port volume on the new heads alone will make a big difference. The old combo was a low buck deal using junk MP pistons (heavy, single pin oilers, big rings, etc. ), chunky Manley H-beams, etc. This new combo will using top shelf items. Lightweight diamond pistons with .043/.043/3mm rings, 7.100 Oliver rods, and the K-1 crank if it can be saved and a Callies if it can't. We're looking for another 100hp on motor and a bigger gain from the 300 shot with the additional volume.
That engine ran great that way. It’s living the easy life in a bracket car last I knew. I’m running the aluminum 540 hemi now with 1/16 AP Stainless rings and still twin 76s on E85.Thats a lot of heat to transfer thru .043" rings. If the pistons aren't done you might want to rethink that. Either way a stainless or Hellfire piston ring.
