I'm leaning towards the "devil I know."

I researched the throttle body injection systems several months back out of pure curiosity and noticed all were 4150 flange. My new engine came with the MP/Barton single plane with the 4150 flange. I questioned the builder and they said that they use that intake with a tapered 4500 adapter to increase velocity. I thought that this might be a good time to really consider one of the new TB systems as I now have an intake that would bolt up without using a spacer.

I'm a few weeks away from crossing that bridge. Just hoping to see a few examples of big cube high hp cars using a TB Plug and Play kit.

Thanks!
