New to the site and just wanted to say hi. I have already found a bunch of upgrades and tips for the 4th gens thanks to this GREAT site. I have two 75 pontiac ventura sj hatchbacks both blue and white with white interiors. One will get a 6.0 ls and 4l80e and the other will probably get a 350. As soon as my dads el camino is done I will get started, just collecting parts needed right now. Will post pics when I can dig them out of the garage.
