I'm figuring even the 305 stroked out to whatever I can get away with will suffice at that point.
Definitely let me know what you come up with.
Once I get the mopar rocker from a friend to compare with and get time for a junkyard run I'll have an fE rocker to test as well.

My build plans so far are pretty much more air flow, compression, and lightening the rotating mass.
.060 over Flat top aluminum pistons that are lighter and 4 ring. 0 decking the block. Shaving the head if I can still get away with .450- .500 lift on the cam...and pending on rocker ratio I'm not sure what that will be on the valve lift so that will have to be calculated. Keeping the total cam duration low so peak power is at 4000 tops.
Opening the head where ever I can....magnum heads for sure with bigger valves. Issue then might be the 4.25 bore may be to small and valves may hit. Rods are beefy enough, but I want to see about taking some weight off the crank and doing more balancing.
Magnum manifold has already been machined for a 4 barrel so I have that done, and then need to make some headers. Hoping for 9.5.1 or 10.0.1 compression. If I can make 340 foot pounds naturally aspirated out of 305 cubic inches I'll be super happy. Can really make an embarrassment out of 350's then.
