Holley Avenger TBI

[OldesI6]

I know this forum deals with MS, but would this Holley Avenger TBI work in place of a carb on a 300?

You can still ask questions pertaining to fuel injection on this forum, not just MS related.

To answer your question, the Holley TBI you mentioned might work on the 300cid since it is rated for 200 to 400HP. You would need to know how the Holley unit handles the distributor input, and whether it would mind six instead of eight spark events per revolution.

You would also need the 4Bbl intake for the 300 to install the Holley unit.

I did not think of the 6 sparks instead of the 8! I'll send an email to Holley and ask. Thanks Rocklord!

definitely have to ask because they have some stuff that says its for a 6 cyl but non of the systems say they are might have to custom order it.

It will work with a six, but you'll have to call the tech line to ask for the specific part numbers you need for the harness. The Avenger will only control spark if it's hooked to a GM distributor so it would be fuel-only in our applications unless you adapted a 4.3 V6 dizzy to the engine somehow.

 

[OldesI6]

Thanks for the reply Mustangsix! I have not contacted them yet, but I can understand what you are saying.

What are you trying to accomplish by converting to EFI?

I'm curious as to why you wouldn't just use stock Ford EFI stuff from a wrecking yard and control it with some programmable controller, Megasquirt, SDS, Haltech, or any other one?

Don't mean to revive an old post, but there's a good question here.

The Holley Avenger TBI, as well as a few other TBI kits, states the capacity to control timing/spark events in HEI systems, which of course is typically GM systems. Isn't the DUI distributor (Classic Inlines) based on the GM HEI design? Assuming such, and considering that CI lists a DUI-EFI distributor, shouldn't this distributor be controllable by an aftermarket EFI system that is HEI compatible?

Holley nor Performance Distributors, specifically list any details on what systems are compatible with each other. Thoughts?

Should be able to use the Duraspark dizzy, it's cheap and it works. I have been playing around with my Megasquirt setup, found a combination for my 300 that should work out great...I'm using a Duraspark dizzy in conjunction with a GM 8-pin ignition module and coil off of a 350 Suburban. Haven't seen any problems with this setup while testing it on the bench, seems to have a pretty hot spark and works well with the Megasquirt. I kept all the advance mechanisms in the dizzy and set the ECU up to control fuel only. Just so everyone's aware, if you use the wiring schematics on the internet for connecting the GM module to the Duraspark, most of them I've come across are backwards. On a Ford distributor, the orange wire is positive and the purple is negative. (8-pin has the inputs marked "P" and "N") Also, the "Reference Low" pin should go to ground.

84ford,
Any particular reason why you went to duraspark and GM module as opposed to TFI controlled by MS?

 

[84FordVan]

Basically I wanted to start out with something that I know works as far as ignition timing goes, always had good luck with the Duraspark before. Just didn't want to be tuning spark and fuel at the same time, seemed like a headache. That and I couldn't find anyone with a timing map for a stock 300.

 

[E4ODnut]

Nothing wrong with that logic. Part throttle timing can be tedious to set up on the road. It's best done on a dyno if you have that option.

Not to hijack but does anybody know if the avenger kit would strap to a 200? With a 2v converted log head?
