In 2003 I bought a 1971 Nova coupe. This thread will track my rebuild of this Nova.
Originally a 250 inline 6 and powerglide it now is still an inline 6 but converted to a Saginaw 4-speed, Holly 4-barrel, Offenhauser intake manifold, and HEI distributor.
I bought the car in 2003 and drove it all that summer. I did some cleanup, tuneup and a few upgrades over the following winter. The summer of 2004 was my last driving it. after that it went up on jackstands and has been there pretty much ever since.
The first thing was tear down. It was originally from Virginia and compared to the Northeast cars was in excellent condition. Not to say there wasn't some rust issues. The floorpans had rust throughs in front foot areas on both sides. The front fenders had holes behind the tires and the rear lower 1/4 panels needed to be replaced as well as 2 small spots in front of the rear wheel wells.
For right now the I6 is staying. It runs excellent and the 20mpg (so far) is not hard to take. There is a low key "car show" at our local Barnes and Nobel parking lot every Saturday night and the inline always draws a cluster of folks asking questions. Fun. If anything else made it's way between the fenders it might be an LS variant or maybe even a late model inline from a Trailblazer. With the OD transmission and A/C the Nova would be a pretty sweet ride.
I did consider going the fabric spray route. I also found that IGGEE makes a half way decent vinyl seat cover that nearly matches the rear seat upholstery. The problem is that cost is pretty much a tossup. I have the front bench seat upholstery already, $200.0 for seat buns and I could have the bench back in there. The IGGEE seat covers are nearly that. Or custom for a lot more.
