Pinion angle is generally around 2 degrees -- depending on how hard you want to hit the tire -- and engine/trans centerline should be "pointed" aor angled at the pinion -

What kind of pan clearance are you guys experiencing with such low crank centerlines of 12” and below? I’ve got my 68 Firebird sub frame mocked up so that I should have about 6” from flat part of my rocker to the ground.

This allows me to modify my crossmembers to allow a low crank centerline but I’m only going to have about 1-1/2” off the ground to my 20490 9-3/4” deep Moroso oil pan.

crank center at 12 -- pan depth of 8 ish gives you 4 in of ground clearance .-- time for a new pan. and depending on the cars use -- 12 to 13 crank heights work ok.

You’ll have to have a different pan. That’s too low. You will bang it on everything. I think we ended up with about 6” or so. It uses the 7 quart pan. My other car sits way lower and the only pan that will fit is a dry sump pan.

The Raven is crank CL ~ 12 3/8 at ride height, engine set back as far as possible with stock firewall.
