I'd do an updated version of dave's super duper mileage 318.
1) start with a mag 318. I'd pull the heads, measure how down in the bore the pistons are. should be ~.055 or so.
tear down to bare block, have the block decked ~0.035 to 0.040" and then run the Mr. Gasket .028" thick head gaskets
get the cam reground by bullet, using bullet's HR259/316 lobe for intake and exhaust. more economy, drop to the HR252/320 lobe on the intake
do a little home porting on the magnum heads following dulcich's may 2005 mopar muscle article-- get the heads redone, opening up the valve job to take advantage of the 1.92/1.625 valves. use hughes #1110 springs and retainers. redrill for LA intake
intake, I'd look for an LD340 or LD4B, open up to accept a t-quad, run a small tquad
I'd run headers.
tranny, I'd keep it simple and run an iron case A833OD if I could find one. aisin R154 would be second choice.
rear gear, 3.23's with the A833OD is a nice combo with 25-27" tall tires. if running 27-28" tall tires, you could go to a 3.55.
That sounds like a good plan... but you're definitely spending way past my budget here.
I'm still on the fence about the 833OD but i just cant get past the ratios. I was in a Demon with a hot 340 and one ov those OD's and i absolutely hated that 1-2 shift. Why the hell they didn't change the 2nd ratio as well i'd like to know.
Another stupid thing is i just sold one ov those last year...
