Well, I installed the holley sniper so I am not the one to ask about modifying the carb. I think my old carb had a crack in the base of it that was the source of so many of my problems for many years. I suppose I could have installed an new dizzy from holley or some other manufacturer, but that sniper install, all together, cost more than I even care to count. Probably around $2500 after all the other mods I did "while I was in there". So a $20 set of springs and a little 1/4" spacer just to get it in the ball park was worth it I think. Certainly, having a dyno and being able to actually see what's happening on a graph would get you spot on. I know it's not cheap but Jim C is the one to send your carb and dizzy off to for a total setup. Until I pull this engine and have it completely overhauled I don't plan on doing anything else with the dizzy. If I ever get that 2F built up to Mosley specs then I will absolutely get the dizzy dialed in perfectly with everything else. I've read some amazing stories about a Hi Pro 2F with the sniper.
Looks really good! I'd be worried about the extra leverage that the rack has on the mounting brackets since the weight won't be directly on top of them. I'm not an engineer, but I would think your weight capacity will decrease because of that.
