Re: Holley Carb tuning questions
 

I have a very similar combo on my Formula and went with a 750 v.s. Barry Grant Sea-Demon. I went thru all the normal tuning procedures. Out of the box it was RIGHT ON. I went up on the jets but found the stock jetting was perfect. Same with the squirters. Same with accel pump and powervalve. Rum-Runner gave me some advice and he and his products are TOP-NOTCH. I probally gave up some response going with a 750 over a 650 but I figured the 750 would be a easier re-sell or would work with more HP or Cubic inches.......
