My son just bought his first car, a '77 280 that we will be restoring together. We totally gutted and stripped it down to the shell last weekend which was a lot of fun and he learned a lot. My question is in regards to the fuel injection system on these cars. My plans were to install a little larger cam, I think MSA calls it a Stage 1 cam along with bumping the compression using a new set of pistons, but I could not find much information on how much compression or cam the stock EFI system can handle. The engine has a freshly rebuilt N42 head but it does have the stock bottom end with the dished pistons. BTW, we do not have the budget to install an expensive aftermarket EFI system. If anyone has experience with this I'd like to hear your comments and suggestions.
