OK, I’ve read some of crackedback previous threads on this. Seems like he’s more concerned about power than drivability. I could be wrong and don’t want to speak for him. But I understand his point that you can probably make a mechanical secondary work just as well as a vacuum, secondary with tuning and I won’t argue that. The question is am I capable of all tuning and would vacuum secondary be, more useful to me with my application.
For me, I’m trying to make the best of what I have. And what I have is not ideal at all. I have an automatic with an engine that was really designed for a four-speed racecar. And I’m trying to tame it. The engine has a 12 to 1 compression ratio And I do not have the cam specs. I’ve gotten this to run before and it was fair. What I’m trying to do is to get it to run better. I am willing to sacrifice 25% power for drivability if need be, I have on hand a vacuum secondary carburetor , i can get my buy a vacuum advance distributor to work with my MSD 6AL. But for now I’m just trying to make what I have work better. And learn as much as I can from you guys thanks, Ron.
