First things first cubic inches cubic inches cubic inches. Vacuum is the easy part any good custom ground cam can get you to put what ever vacuum you need.

The motor I have is in between 400-412 cubic inches . I don't want to tell a whole lot due to other readers who race with me .
Don't know who you are....... but if I race against you in the vacuum classes,,,you need to get an RV cam! They pull good vacuum and if they can pull a big RV ten they can pull your truck easy!!:D

If you want to go fast, listen to Derrick, he's on the money!!:D
