'68 Dart with a 318 LA - Build Options
Juse use the performer intake and holley carb. My teen ran better with th performer than the d4b. Rering and all new bearing if bores are good. Otherwise bore with new Pistons. Summit sells a 340 repo cam that's cheap and will work fine. That with headers and gasket matched and bowl blend 302s will be a stout 318. And use Mr. G .028 gaskets.
