Hi All, I am about to pull the trigger on an order for the 1969 Corvette. A buddy and I plan to have a day of tinkering two weekends from now. One thing I have learned with this particular car is to: prioritize, prioritize, prioritize. You never know when something important can come up like a rusted out gas tank. It is best to afford things if they has a significant impact. So far the list of things that need attention is long: suspension bushings, rear leaf spring, emergency brake, weather stripping, and more. Best to be careful with limited resources. I want this engine running as smoothly as possible. That would go a long way to give me great satisfaction, enjoyment and confidence. If it runs smoothly, I am more likely to take it out for a drive. So far we have replaced the cam and lifters, reset the ignition timing, rebuilt the carb and added an electric choke, rewired the engine bay, given full battery to the ignition, reset the throttle linkage geometry. We also replaced a torn trans mount and moved the exhaust pipes away from banging on the body. Things are much smoother. We tested a fuel pressure regulator and that improved things even more. I will be adding one permanently. The ignition cables are in at 1,500 ohms per foot. I will be replacing that with a set of 50 ohms per foot + new plugs. The distributor, an HEI, looks new and of decent quality. My question is this (and we finally get to it) what impact would an MSD Street Fighter Box and matching coil bring? Beyond the new plugs and wires... will it further improve idle and upper RPM? Or will the difference be marginal? MTIA ! D.
