when i still had the 1050 on i did have the block off power valves installed and it was fine at the sea level but when i brought it up to my 4000ft elevation and got fuel in the oil pan i said screw it and went with the 750 cuz i thought that the dominator was just too much carb. also, im running 8An line for my whole fuel line and have both lines in both bowls.
Another thing too, is the cam manufactorer said the cam should have 8-10" of vacuum in gear. Is that a big thing to worry about?

Thank you guys for keeping with me on this.
