Do a fuel pressure test, also which engine does your roadmaster have? 305? 350? TBI? or the LT1?
350 dont no the other tbi or lt1
anybody else got any ideas
The TBI will have a large air cleaner on the top. The LT1 does not. Along with a fuel pressure test, try checking the timing. It may be off a little.
