I was told that i could mount a 350 in my car and use the stock 305 tbi setup. Has anybody tried this?? Can i use the stock tbi unit, manifolds, computer, fuel pump, and everything else. Just buy a 350 long block and make it work. Would i need a larger tbi with bigger injectors (like the holley model)?? Any suggestions on getting best bang for the buck?

 

yes all will bolt up

 

Check out the TBI board, much more info than here.

 

As for high-po parts, you may be able to use some stuff from the 95-99 Tahoe/Yukon/Suburban line-up.

My '96 Yukon does remarkably well for a TBI 350, which is rated at 255hp.

 

I recently replaced my TBI 305 with a 350.
Swap is best done by replacing injectors, knock sensor and module.You might need a chip too.
I had a custom chip burned for mine.Adjustable fuel pressure regulator makes it very tuneable,and may eliminate the need for bigger injectors,if it's internally stock.
