The "regular" Edelbrock Performer intake manifold is pretty much an exact copy of the factory Pontiac manifold except lighter. The RPM places the carb about 1.5 inches higher than stock. Might cause hood clearance issues with a stock air cleaner. Definitely causes issues if you decided to add an aftermarket Ram Air setup. Keep the Qjet.

I am really likeing my aluminum Rodney Red radiator. As my build was progressing, I constantly saw overheading issues and was determined to avoid them. If you do a search here you will see that making sure there is minimal clearance between the water pump impeller and rear plates makes a huge impact.

Subframe connectors are typically a good idea for a 'vert, especially with more HP than stock.

You definitely will want to stay away from 14 inch wheels if bone stock is not your thing because one nobody except repro tire places deal with that size anymore. That's also starting to happen at the 15 inch size (Firestone Indy's are gone for instance). Year One now offers larger Rally II reproductions and Vintage Wheel offers even larger "rally II" look billet alumium wheels. Tire size becomes really critical at the larger sizes and I would recommend doing a search here to see which size combos work best. My thinking was to always go with a final diameter that is really close to the factory E size that came on my car.
