Baseline jetting
I'm in the process of piecing my 454 back together that I found water in this spring. It started as a stock 330 but will now have a set of factory rect. port heads, dual plane intake, and a 750 DP. The valvetrain and comp. ratio will be unchanged. I know this isn't a great combo, but the budget for engine upgrades this year was zero (until the water problem). I'm needing advise on carb jetting. Right now the 750 has the original 73/81's in it. I just need to get it close until I get on the water and start tuning. Thanks.
