What engine? GM is still making pans,..that's where I'd go. I'll never buy another Moroso,..bought one for a 496 on a 69 Camaro and the radius was bad at the rear seal causing me to pull the engine twice. Went to a Milodon,..no problems.
But by going GM you know your oil pump pick-up would be spot on.
Good luck!

when researching for your pan, also consider some vette owners have had issues with oil pick-up, or lack thereof, during hard braking, cornering, etc. So the pan baffling needs to keep oil at the pickup during these manouvers. most gm pans have little or no baffling around the pick-up (but haven't seen the brand new ones; maybe someone could post inside pics). not sure if there is anything on this forum re: this subject, but it's been documented in other readily available references, however, the articles are old and havn't been updated to my knowledge. one article i found refers to modifiying an aftermarket pan to fix the pick-up issue. i contacted the same aftermarket manufacturer (well known brand) about this and got nowhere with sales; and couldn't get through to engineering; was hoping they had incorporated mods. for daily driver type action, a gm pan, windage tray, and pick up should work great. many run the 8" deep gm pan with no issue. but if you need less depth (more ground clearance), my experience last year was no luck finding an off the shelf item with good proven baffling from any aftermarket brand.

I have asked many if that pan would fit a BB vette to no avail!

If you want genuine GM, just get the old LS-7 pan/pickup and windage tray. It's a great pan and should fit OK. Never any pressure issues with it that I've ever heard of.
Well actually, I'm not sure if it clears PS if you have it. Might need to check that with someone else.
Otherwise there are a couple of other hardcore pans out there, but I'm not sure that's what you're looking for.

Course I'm trying to measure with vette sitting on the ground
makes reaching under a little difficult

I did a rough measurment & found the pan from a 86 BB truck to be only 1/2" deaper than the pan that's currently on the 350 in the car!

Try measuring from the pan rail down and from the lowest point on the rear main down. Grab a straight edge for the bottom of the pan and take several measurements. Also use the tranny and tranny dust cover as general reference points for eye-balling, maybe that will help. I think you'll end up having to jack up the car. Trying to measure for PS clearance is tricky without fixtures; i missed it by about 3/8" on my first try using tape, squares, and fiddle-t-widgets. The assist cylinder is closest to the pan when wheels are locked left.
The 1/2" lower on the 86 pan would be great if all else works; i'd assume that the windage and pick-ups are different.
427Hotrod has good suggestion too; you may find the old LS-7 pan/pickup and windage tray to work well. If all you have is dings on the factory pan, seems like the easiest solution is a replacement in kind.
If you mix/match parts, just make sure to check the standard items like oil pickup to pan clearance, etc., and that the windage scheme is consistent. If you are already getting dings on the pan, don't consider AL, stay with sheet metal.
