Holly VS Edelbrook

I am running a Chev 350 motor in my CJ. The Holly truck Avenger is well thought of but I see that Edelbrook offers a Thunder Series Off-Road. Anyone have any thoughts on a comparison between the two?

I don't know much about either personally but I'm doing a lot of research on them both now because I'm finishing up my 304. I'm leaning towards the Truck avenger simply because I read somewhere that the Edelbrock off road carb should only be used off road only. Not sure why and I just looked and I didn't see that on the Edelbrock site @ a quick glance. I drive to most of my wheeling outings so this puts the Edelbrock @ the bottom of the list for me.

Years ago the draw back on the Edelbrocks were they required a lot more to tune them. Lots of needles and screws to turn and adjust and many folks weren't that toned in carbs to make those modifications. Just looking over the Edel sites the last few nights and they seem to have come a long way from that for eased of tuning. So my only concern would be the off road used only thing...

I have the Holley truck avenger 470cfm on my Chevy 4.3L V6 and love it. The PO had an Edelbrock (non off road model) on my CJ and it would stall during off camber situations. The Holley TA has been easy to tune and is great on/off road IMHO

Barry Grant, preferably speed demons. I dont think they have an off road specific carb. But all their carbs a easy to tune, have special features found on the high level carbs from the other guys. They have smoother bores/venturis for better airflow and better power. And finally they look like a crown jewel on top of your powerplant. Best of all they arent super expensive.

On my maverick I went from a misbehaving street avenger to a 750 eddy, picked up a lil power decent enough, but didnt really scream, then I went to a 650 Mighty Demon and it "felt" like 40 hp. It honestly made my engine feel rauchous.

When I do up my 360 with all the goodies itll be a demon sitting on top of it.

Not to bash your Barry Grant, but will it run off camber? I've seen way to many vehicles run excellent in the garage, put them on an off-camber spot and they're dead. They get winched to the top!

I really doubt that Edely's are a off road only carb, not sure what would make them an off road only???

Just started researching it. And BG as of 2010 was developing a off road carb, i dont know if they ever did though. I do know they build holleys too so I would imagine they would set up one for off road on request. Also someone in another forum mentioned race cars, like road course or circle track. Which both involve high Gs and cornering loads.

Funny thing.... almost all my jeeps with stock carbs have sucked, sputtered, died, and backfired on the street. But once in 4 in the mud holes and the big hills. They run like a boss.

Ok just talked to Barry Grant. They went through company restructuring a few years back and discontinued the off road line. He did say however that their new street demon has the same features as edelbrocks off road model and should be well suited to off road applications. I retails for under 300 if im not mistaken, and is a very simple carb, with smaller cfm options.

So they may not have a screamer for jeeps, but they have a simple, cheap, quality tool thats will make a jeep perform as it should.

Hmm...not exactly a glowing business report.

I tend to pass on "re-structured" companies. It usually means they've gone thru bankruptcy and have screwed every one of their suppliers along the way.

Well you say that but it happened right after the market went to crap, around the time everybody was screaming for more hybrids, and so yes the smallest, although well respected, carburator company did have to go through bankruptcy. Unfortunatly the government spent all hot rod industries bailout money on banks.

Edelbrock has much more than carbs, holley could just go to the junkyard and rebuild a million cores to turn a profit, but Barry Grant a stalwart in the hot rodding community only sells carbs. They actually folded and closed their doors, many magazines wrote articles about this. And there was a massive consumer outcry, which led to them being able to find the capital to resume production. Minus a dedicated off road line.

They are a good company that makes good carbs. The fact that their tech department responded to an email in less than 30 minutes is a testament to that fact. Anyways take a look at a demon in person and you will see the quality for yourself.

Yes, I know about bankruptcy. I helped my father-in-law's manufacturing company avoid one during that same period.

Our reason for not gong the easy bankruptcy route was all of the smaller vendors and suppliers who would have been screwed. We just couldn't do that to those folks, many of them were friends, so we worked our way thru it and eventually got everybody paid.

I don't have a lot of respect for "restructured" companies. It's often not the owners, or corporate officers, who suffer in a company bankruptcy, it's the smaller suppliers, who they owe money to, who suffer.

Edit: Op, sorry for the momentary hijack.

Im just in it for the performance man, I may not like a company for this that or another reason but if they make a superior product at a good price Im gonna bolt it on.

Well Ive given my vote on the carb debate BG on an Edelbrock manifold. Ive given my reasons and dont need to get into a social economic debate.

You say your are in it for the performance, but you also say all your CJ's with stock carburetors sucked, sputtered, died and backfired...hmmmm.

...and now without fixing your jeeps manifold leaks, timing and carb tuning your just going to bolt it on

Just trying to figure out where you are coming from

OP...The Carb Shop in Ontario CA can build you a custom carb for your specific application. They will tune all the air bleeds, jet, power vavle and completely calibrate your fuel curve for your engine. I know Matt can vouch for National Carburetors as they do a fantastic job as well.

I'll add this for the OP's consideration....

There's a reason the Rochester Quadrajet was the most popular and widely used four-barrel carburetor in General Motors' history. It's also considered by many one of the best off-road carbs.

Just food for thought.
