since i'm done with helping any one person, i figured i would share!!! 1st. the whole time i helped jack jr we never cheated and there was NEVER any titanium on the car, NONE!!! so here's a list of what we did have: stage IV stewart pump=2+hp saved, cv products LOW drag ps pump=2+ hp saved, 1 belt - the w/p-crank belt is nice insurance but a lot of drag, 17" plastic fan with the rad moved back so we only had a 2 1/2" spacer, 2- 1/2" spacers matched in the middle and matched at the carb like a s-sucker and matched to the intake[radiused the length of the divider xcept for about 3/8" where it met the s-sucker shape of the upper] smaller is better on the o.d. where they meet, we ran a taco 750 the whole time i helped...i just had to redo some of the sloppy work he did also a lot of fine tuning on the xclrater pump set up, i had ground 10g straps from the dist clamp to the back of the cyl heads, used cheap ass bosch platinum plugs[1.99 each and never had a problem] indexed wi the gap towards the intake valve[the largest part of the chamber], never ran the timing at more than 36 deg, once the motor had a few nights on it i would run 4 gts of 15/50 and 3 1/2 qts of 0/30...yes 0/30 - never hurt it!!!], also after break in i went to slightly heavier springs and would heat cycle the motor for a couple hours in the shop at about 2500 keeping the temp between 200 and 220 wi a piece of cardboard...this seemed to free them up[running it at a temp it never saw on the track makes all the parts expand and wear more clearance, once it wore at that temp, the friction would be less at a lower temp(always ran around 180 on the track)...i guess!?], leave the heat plenum crossover un-plugged - this lets heat out of the intake, the headers we got from ricky made a big difference and the motors always liked some back psi[also if you run standard sbc headers, you need to slot the holes to move them up...vortec heads have the exhaust runners .100 higher. the top of an exhaust port is the last place you want any restriction!!!], ran a deep cycle battery and a hot module and coil...but no msd. thats all i can think of on the motor. the rear: i think that if you go with a 4:11 rear[instead of a 4:86 like we ran] it will save another 5-10 horse especially if you get a REM finished R&P wi the ring EDM lightened, all angular contact ball bearings, i ran a 50/50 mix of shafers[sp] and light weight gm synthetic trans lube[about 20 weight!] in the rear wi no problems, also ran a 50/50 mix of shafers gear lube and shafers molly grease in all the hubs. thats enough for now! set up!? i'll post it some time, but you won't believe me!!! good luck!
