    I can only tell you ported and fairly modded. With full 3" exhaust the Charger spools the HE351 in 4th gear right around 4100rpm @ 20psi pump 91 oct.

    Through the open 4" dump it's full spool 39psi @ 3900rpm on Q16. Most I've heard of seem to be spooling about 500rpm slower, even on the 16v's. Not sure why........

    How much HP are you making and how do you Know your .63 A/R stage 2 is done? Pressure tap?

    In an L-body I would go straight to the 2.2, but that's me. Heavier car I would go 2.5, but Any 2.5 I would built would have a properly installed and centerlined F4 cam in it. You end up with a 2.5 that Thinks it's a TQ'y 2.2 lol

    Car has been off the road 10 years so the doner engine is a 2.5 and that will be ok to get it running on then build another engine. I'm sure I want the revs of a 2.2 tho

    Never did a pressure tap but with the wastegate hole bored out to within 1/16" of the flap I can't control boost below 22psi. Also I build that 22 psi way below peak power putting lots of stress on my rods. Engine is a 2.5, FM big valve head with combustion chamber work, BMF intake, Log manifold, and t3/t4 50 trim. Running on e85. Have not dynoed it yet.

    Fellow l body owner sent me a picture of this and it's pretty much what I would want. Not sure if it will clear the bmf intake inlet tho
