I want to mount an LQ4 1.5"-2" forward of the stock sbc position in my 85 k3500. Will the oil pan clear the engine crossmember with it being mounted that far forward or will I have to cut up/modify the crossmember?
I'm mounting it that far forward because I'm also swapping a 4l80e in and it is 1.5" longer than my current setup. I want to keep the trans crossmember in stock location and retain current driveshafts
On my 87 half ton i made 1/2" spacers to go under engine mount on frame side to clear the cross member.
i came across this cross member not to long ago. http://pacificfabrication.com/73-91-...mber-kits.html
So you mean you lifted the engine up 1/2"?Quote:

The trans cross member bolted up in original location and i didn't have to modify any of the drive-shafts.

I'm going from 350/sm465/np208 to 6.0/4l80e/np241. I'm going to use the adaptor that currently between the 4l80e and np261. The new adaptor is shorter resulting in only about 1.5" overall length increase.Quote:

it was 2"-3". Doug Thorley headers fit great with engine all the way forward.Attachment 9875
