first post been looking around on this site for a while for info. have found alot of stuff..got a couple of questions..can u use regular headers with the lm7 in the 79? will they clear frame? will the stock oil pan be ok to use or will it not work? any more info on this kinda build would be nice. thanks for the input

 

I have an 87 gmc that I am installing a 5.3 in. I am using the colorado\hummer pan http://sdparts.com/details/gm-factor...parts/19212593 My truck is low with a 6 inch drop on the front. If yours isnt very low the stock pan clears but is lower than the crossmember approx 1 1/2 to 2 inches. I am using stock manifolds as I want to go turbo later. Scads of good info here. Its a long post 60+ pages but worth a read.
