    I have a 350 TBI thats getting tired, atleast that what I tell myself to justify this upgrade. I'm trying to figure if it would be feasable to transplant a 454 TBI in its place. I want to retain my computer to control my TH700R4. I also have a Holley TBI which is rated at 670cfm (it claimed to be 42% larger than stock). my question is could I use my computer with a reprogrammed chip, my distributor, and the holley TBI on a mildly built 454, if I can't locate a reasonably priced 454 TBI? also what is the cfm of the 350 & 454 TB? thanks in advance.

    The factory 454 TB is rated at 670 CFM. The 350 is 500 something
