The boat is a 89 baja 210 sport motor is a 2005 5.7 hooked to a gen 2 alpha drive. I know I am going to have to be nice to the alpha drive to get it to live but the boat is pretty light, got a drive shower on it. The motor is a stock low hours 4 bolt 5.7 has vortec heads and is a factory roller cam motor. I has a high rise intake with a quadrajet on it still. I just ordered the cam for it will be here tomorrow going to beehive springs to accommodate the lift. cam is 212 intake and 218 exhaust at 50 with .488 int .495 exhaust lift with a 112 lobe separation to so we don't get reversion. Exhaust is glenwood manifolds with stainless highflow risers turn downs and 4 inch out the back with no muffler inserts. Motor is out of the boat almost disassembled for cam installation.
Here are the questions I have:
1. I am dumping the Q Jet and installing a 650 DP holley for carburation it has J tubes but it was originally a car carb ( I know) does anyone have some setup specs I should start with like jet sizes go a little richer or leaner then stock. Power valve size to start with if different then stock 6.5 or if I need one at all in a boat.
2. Thunder bolt ignition is hitting the scrap bin too going to MSD 6 box with MSD distributer. Question is on the curve and how much max advance was thinking about starting at 36 max and get it all in by 3000 if it dosent ping give it maybe 38 or so. Motor is set to spin 5200 with a cleaver prop on it.
3. What is the stock compression on a 2005 260 HP 5.7 as that is what the motor started life as?
Thanks for the help
