looks like you have done a lot of the things I intend to do to mine....
mostly the new tank and EFI. Id love to hear your thoughts.
The tank and EFI I did on the cheap, could have saved a smidge more, could have spent a lot more.
I got the idea from a guy that did a complete drivetrain swap from a Roadmaster Wagon, he did it like the factory would have if they were still making El Caminos in the 1990s.
Some info on my swap.
I got the FiTech GO EFI 600 for $800 with a 10% off coupon, and a $100 rebate. My total was just over $1100.
Tell me about your wheel/tires.... size backspace?
They are 14" 1980 Camaro Berlinetta wheels that I masked and painted. I think they are 14x7, no idea on backspace. And they just barely fit over the single piston calipers (1969 style discs). One wheel self clearance for a couple hundred yards, and never made another noise.
I also got them cheap WITH brand new lug nuts. (they take a special shanked nut, I guess mag style with washers could work also). They are very similar to the 1980ish Z28 Wheels, and 1987? Monte Carlo wheels. The Monte Carlo ones take normal lug nuts, and have a different backspace.
The tires I had were 227/70-14 in the rear, and 215/70-14 in the front. They were very old with about 15 years in Las Vegas, so last year I saw these at Walmart and bought 6 of them, why? That is all they had! They were Douglas 205/75-14 and while they look a bit boring, they are a great size for just normal driving. They were $30 each! and for $220 total for all 6, 5 of them mounted, and 4 of them balanced out the door with taxes and disposal! And made in Ohio! I really like the Cooper Cobra's and was ready to buy 4 new ones until I saw those on sale.
Is your car at stock height?
No idea. With 215/70-14 on a high crown bumpy back road, it would hit the road surface on the K frame on a bump. I like it how it sits, well it sits with right rear low, until I get in.
I also replaced the air shocks and they can sit months and still have pressure. I am installing a GM vacuum operated pump and controller to vary the pressure while driving. My dad got it in 1996 in Las Vegas with 66,000 on it (now 99,000) and who knows what is stock.
It was a 327, 3sp manual column. Now a ZZ4 350 700R4 OD.
