305 TPI to 73 350 Rocket Carbed Swap
305 TPI to 73 350 Rocket Carbed Swap
I need to know what i will need to do with my ignition system, exhaust(will it match up?), fuel system(I have an electric pump now and will it work with an Edlebrock 750cfm?), also does the 350 turbo tranny use the same length dtiveshaft that my current 700r4 use?, and what about motor mounts? Your help would be greatly appreciated guys. THANKS

To keep it simple, you would have to do something to everything you listed. And, probably some more. All of it will be custom made, nothing will be available off-the-shelf.
The easiest part is a regulator to drop the fuel pressure from the in-tank electric pump. Otherwise, you're looking at time-consuming, specially-made, most likely expensive parts to put in an over-weight, under-powered engine.
Ever consider a "real" 350? Honestly, that's the much better choice.
Saturday, my first run ever with my mods was a 15.77 at 5800' Bandimere - with a tranny that wouldn't shift from 2nd to 3rd and my cruise-type gearing. Last year, there was a 3rd gen out there with a Buick 455 that ran 15.25. He went through a bunch of work for that 1/2 second advantage, and by the time I get mine running right, I'll probably be down there, too. I wouldn't call his "different" really worth it - would you?
