5.9 Magnum
I'll give ya the rundown on mine
91 360 roller block
Stock bottom end (Crank, pistons, rods) with ARP rod bolts, speed pro rings, new sealed power bearings, and a ball hone job
8.5:1 compression
RHS heads as offerred by IMM engines
Mopar .028" compressed thickness head gaskets to get compression UP
Custom ground hydraulic roller by IMM...Specs were vaguely from what I remember 230/230 at .050, .579int/563exh lift, 106 LSA installed 5 degrees advanced
OOTB RPM Air Gap
Holley 750 Street HP carb
1-5/8 headers, 3" exhaust with x pipe and borla xr-1 mufflers
A833 4 speed, Dana 60 w 4.10's, 28x12.5 et streets, 3400lbs with me in it
Car drank 87 octane pump puke and went a best of 12.35 at 109mph?? but ran consistent 12.3x-12.5x's depending on track conditions and weather...couldn't 60 for crap though (best was a 1.69) but it did this and made for a fun ride! With an automatic and a few less pounds this thing woulda ran high 11's no problem! on 87 octane!
