Supercharged 502 with twin TBI's?

Wouldn't that be sweet? Well, it is. I went to a SLP sponsored event on Saturday and a guy there had a 90's ish Suburban with a twin TBI injected blown 502. It was sweet, so sweet. It ran great, idled as smooth as can be, was pretty damn quiet, and was fast as hell. I didn't see him run, but over heard someone say it was in the 11's. Sweeeeeet.

A blown 502 should/could have 600-700 lb-ft, that'll push a 'burban...


Did you talk to him about PROM work/how'd you do it???

Yeah, I'd like to know about the prom work too and the wiring harness. I eventually want to build a 383 or 400 SB with duel TB's. Either that or Turbo charging my 305 once it's built like I want. Neither one will be easy but I'm sure it'll be well worth it.
