My plans for the car have also changed. I ended up finding and buying a 1 piece 70 GTO front end on another forum that will be delivered tomorrow. Ended up costing $500 delivered to my house. Couldn't refuse that deal. :-) Something I have always wanted to do with a car.
So will be going back to the original plan of making it look like a GTO, while also restomodding it. I have another header panel that I have to put on for right now to get the car through the summer, then this winter's plan is to do the body including the new front. I still have to come up with a fiberglass hood. Haven't told my wife about that part yet.
Also got a set of Flowmaster(?)(flowtech?) coated headers for $80, and a Pypes 2.25inch exhaust for $60. Both on Craigslist. I know the exhaust is a bit small, but for now with a 350 it will work. And get me on the road sooner. Just have to get the stuff on the car now. But I have to finish my Blazer first, so my wife can take our Subaru this summer to visit her first grandchild.
