Weiand 6-71 on a 355, Dart 200cc heads w/ mild port work, 2 9379 annular Holleys, Crane 238/248 @ .050 solid flat tappet, 7.83 static compression. 1:1 drive ratio pulleys. This is a friends engine and he wants me to help him with the base tune, base and total timing, jetting etc. He doesn't know if it will run on pump gas or not so I told him I would get advice from this section. Any input is appreciated. Intake centerline is 109, however, it has been set at 112.
