I was thinking I could use a 454 setup on my mildly built 460, just pull all the sensors I need from a junkyard 305, weld in an O2 sensor bung and wire it up. Three questions:

1) is the 454 TB larger that a 350 TB? Or do they flow the same volume of air and have diffrent injectors?

2) I am assuming I will need a computer (or at least the chip) from a 454. Is this correct, or will any V8 chip control the stuff the same?

3) The big one, I am running a stock Ford mech. advance electronic distributor. Can I make this work to signal the computer?

Thanks all,

#1 Yes it is...and still not big enough for a 454 lil lone a 460 which have a tendancy ta like lots of CFM

#2 You would need to run a tbi 454 Manual trans ecm...along with all that fun wiring and sensors.

#3 What most peeps do is buy a aftermarket street rod type kit and adapt it to derr truck...but due to the lack of airflow with a 454 TBI I would find a diff alternative...like a Howell unit using a 4BBL throttle body.

1. 4.3, 305, 350 shared the same TBI, 454 was bigger. I think Holley makes an aftermarket throttle body that works on a GM harness. Perhaps you could get a harness, pluter, etc from a 4.3 or 305, and use that.

2. The computer should be the same, just a different chip. There was a thread on the computers recently, I think it was on a Toy conversion.

3. I can't tell you how to do it, but I do believe its possible. it may involve putting some GM parts into your distributor. Davis also specialises in putting GM distributors into other makes, perhaps they can help (Davis Unified Ignigtion?).
