3.55 is usually the best all around option . Boost from 4K and up ? I’d say it’s linear with the centri blowers from my experience . I’m not sure whwtxpulley setup you have . Sounds to me like a 3.33 /6.87 deal . A real pulley would give it a kick in the ass .
Linear with better gears and rpm range yes lol. I was just looking at what the general go to was for people. Especially those that drive far. Not sure on settling for 3.55's or 3.73's. Whats everyones top speed with 3.08's and 3.73's?
I'm a n/a guy right now .
you have a small window of boost opportunity, and only 4-5 pounds.
i agree with toolow91, you need to pulley that thing up, with 10 lbs and a gear around 320 something to 355 max you'll need stock in a tire store. I think you need to get the boost to come on a little lower in the rpms then a 308 or 323 gear will work. Most fox convertible 5.0 cars came with a 320 something gear in them, thats what I would shoot for.

Definitely doing pulley change, getting it tuned on meth as well with a devilsown kit and new injectors, maf and aeromotive fuel system. But since i am going through it all i know im going to want a gear change, so i might as well do it at the same time.. my svo had 3.73s but ran out of top end due to the crappy 1984 5.0 carbed intake, and edelbrock 600 which was junk. Headers and cam, and work done to stock heads. Loved the low end of the 3.73 gears though.
