I have a 68 convertible that I am restoring. It is a 400 4 speed car and it is matching numbers. The engine block is the WZ Code and it has the 16 Heads. I just had the engine rebuilt with the block bored 30 over. I put the Ram Air IV Cam in it, everything else is stock. I have the original intake and a Rochester carb with the casting number 29244 KA 1539 which does not appear to be original according to my research. I have rebuilt the Muncie M22 4 Speed and have rebuilt the rear end with 3;36 gears that it originally had. I am getting ready to put it back together. This is a car I am going to keep and I am keeping it close to stock in appearance , being a matching numbers car. However, I am considering putting a different intake and carb and HEI for better performance. Also considering the reproduction Ram Air Headers. Any suggestions for intake, carb, HEI ? Edelbrock combo? I have read that there may be clearance issues with the RPM series. The original intake appears to be in good shape and is an option with a rebuilt Rochester. Am I thinking right that I would be better off with a new aluminum intake and modern carb? Also I have original radiator but would appreciate recommendations for a good aftermarket one. As far as suspension, I went back with stock components. I kinda wish I would have got the springs to lower it a couple of inches but I didn't. It has been recommended to me to get the weld in sub frame connectors, any suggestions there? How about exhaust system recommendations? Last but not least, I have a set of 14" Rally ii wheels but would like to get some new wheels and tires for appearance and stance. Any size recommendations and rim suggestions? Money is a factor but I have went this far so I'm more concerned with doing it right rather than saving a buck . Original color is Meridian Turquoise, Deluxe Black Interior, White convertible top according to PHS DOCS which seems unusual. I have been working on it for 2 years and I'm ready to get this bad boy on the road! Thanks before hand for any advice.
