We talked a little about the 454 being unnecessary for a 318, but the 360 TB has 2" bores, same as the 454, and isn't the 318 using the same TB???

454TBs cost a lot more on ebay (as of a few years ago, anyway) but an extra $50-75 now might be worthwhile for the future.

Herkamer -
Why are you suggesting to get a used Holley setup and then throw most of it away, and buy an MS? (not meant to sound combative). Explain that a little more, plz.

Seems to me that buying that for 2-$300 will get you a Holley TB with Holley-specific injectors, right? Why not just get a GM TB and pigtails at a JY (for far less), you can mix-match parts and pick what looks like the freshest parts, and then splice into the MS/harness that you'll be buying anyway? And GM sensors/parts are at every parts store, you can tweak the GM TB later if you want, Holley not so much on both aspects.


IMHO the only reason to buy a Holley system is to get the 4-inj TB (didn't know MS couldn't run that without mods), but even then I'd say that a bored 454 TB with early injectors and later/or tweaked regulator for more fuel pressure could do just as well and probably be more reliable.
