am i doing something wrong or is there some sort of top secret trick to get the oil pan to work properly with ARP main studs..? mine wont sit flat on the block and i cant tell what its hitting..

 

alright, well i figured out where it was hitting (i think i have an f-body windage tray) but now ive found out the crank and rod bolts are hitting the windage tray...? do i just space it up a bit or do i need to get a different tray?

 

That happens with a 4" crank

 

Lol.. Secret is out of the bag now..

 

so just space it up?

im not used to this race car stuff!!!

oo, wait, i mean i just have extra tall headed bolts in my stock 3.622" crank! ya....

 

i bought a few washers to space it. i think 2 per stud did it for me

 

here is my writeup for spacing the truck windage tray and pick-up tube with 4" stroker and ARP main studs:
