I bought a 98' 5.9 with a bad crank for $100.00. Put a 4" crank, eagle rods, Iron Ram heads, Ross pistons and a M1 intake, MP hyd roller .501/.513 camshaft (the 380 hp one I think). Dropped it in a Volare with a stock 904 with a BTE 3800/10" converter and 4.30 rear gear and it went 11.29 at 119 mph. Had a total of about $3500.00 in the motor. Hard to beat that!
76' Volare, 5.9 magnum w/Iron heads. New best 10.68 at 123 mph 1/4 mile.

I would get a magnum short block. Look for 93 and later 360. Reason I'd go short block is the factory heads crack. I think I've seen one set off a take-off engine that weren't cracked. Anyway, get the short block and go either Edelbrock magnums or those new indy cast iron magnum heads. I think there's one other brand out there that's decent. RHS but I don't know where to find their stuff. I really like the eddies though because they have 7/16 studs and you use small chevy rockers. Lots of those around and very reasonably priced.
Magnum R/T heads are another good head but they need work to flow any better than a factory magnum head. At least mine needed work...
Flowed a whopping 210 cfm.
the Indy ones are RHS's hughes sells them starting at $879/pr assembled. the other brand is also austrailian made, Enginequest. Hughes sells theirs as the "Iron Ram" starting at $699/pr assembled.
I have essentially a slightly hopped up 318 magnum ('86 roller cam shortblock, magnum heads) and I'd never go back to LA for a bucks down build. I had my roller cam reground by bullet cams with their HR259/316 lobe, hughes 1110 springs, 2.2L mopar retainers, headers and an RPM air gap (I redrilled the heads to LA intake pattern), and it makes great power everywhere.
What is you're combo with this? Such as rear end gear and transmission setup? I'm thinking this would haul a&^ in an a-body! Which carb?? Fine to reuse roller lifters?

3.55's, 27" tall tires, 42RH (A500 tranny), eddie 1406 carb (had to lean it out a bit). it's in my 5th ave, which weighed 3950lbs without me. it keeps up with a stock 5.7L AWD LX car from a roll. yes, I reused some used magnum lifters.
guys have done similar combos (but with EFI) in dakotas and been in the 13's....
in mixed driving I'm getting 17-19mpg to boot.

42RH is the alpha-numeric designation of the A500 (46RH is an A518)
the front half is a low gear A904 (well, 998 actually), with 5 disc front clutch, and 2.74/1.54 1st & 2nd gear. the tailshaft area has another planetary (it's actually a 727 planetary from what I've read), that provides a .69:1 OD. it's also a lockup tranny. in OD it cuts my cruise RPM to be like I had 2.45's out back.
