Oh boy, do I know the feeling!! Please don't mention hood clearance issues. It's been a nightmare for me.

We'll find out, the pic makes it look taller than it is. Should clear with a cowl hood, but may require inner structure trimming or an aftermarket hood that doesn't have any. If I can't make it fit I'll sell it and go another way.

Why not DBW?

To get a good looking dbw throttle body is $700-$800, Holley sponsored this one. I've had mechanical tb's on turbos and blowers without a single issue.

What's the diameter?

It's a 92mm. The intake can accept a 102mm but since it's under boost instead of sucking through it like a roots I kept it smaller to keep the intake plumbing easier to deal with.

A 92mm should be ok. I start to worry when I see smaller engine with the big 102mm TBs, especially when using a manual transmission. The 102s flow a lot of air at low throttle input and it becomes hard to drive from a stop. I have a customer who had exactly that issue and now that he has a stock 90mm DBW, he is much happier.

Decided to make you happy... Actually, decided I wanted the Dakota Digital cruise control, and other options that DBW gives you, so I picked up a Nick Williams Performance throttle body.
