With all things being equal which one would you rather have on your carberated Blazer?
I have had both for many years and I prefer the Edelbrock.
Every holley I have ever had needed constant babysitting to run good, and leaked. Made more power than edlebrock though.
more power from holley and better reliabilty in the edelbrock
Okay, I read an article in Petersons 4wheel offroad a couple months ago on the Holley Truck Avenger. The article said that it would handle 40 degree inclines without stalling and 30 degree sidehilling. 40* don't seem like that much. I realize that a person could always go FI. Anyone running these carbs? I have also heard that a good Q-jet is good for wheeling.
Go Edelbrock. Less pieces to worry about, easy to tune and work on. Get the off-road needles and seats, search this sight to find the float adjustment, 3/8" I believe. Those 2 mods and a proper rod/jet combo will work great. I have the 1406 on my truck.
for performance you cant beat a holley. However for reliability and long term drivability without ever touching it, you can't beat the edelbrock
Therefor if racing use the holley
If a DD or trail rig used the Edelbrock
Before going TBI an Edelbrock 1406 with the offroad seats worked pretty good for me (still have it for sale...). It was easy to tune and doesn't have a power valve (like Holleys) that go bad if you backfire through the carb.
An old Rochester Quadrajet correctly rebuilt worked better than the new Holley in Bobby's 67' w/ a new ZZ3.
Amen to that!
Its Holley for me! You definately have to tune the thing more than once, but there is so much tuneability in a Holley. Plus Way more power than a Q-Jet.
Truck Avenger specifically.
ive had an edelbrock, holley, and a q jet and with gas so damn expensive, i stick with the q jet. The edelbrock worked but would stumble a little under hard throttle and stalled a few times. The Holley never stumbled, but it sucked the life out of my wallet because it was a double pumper and it stalled all the time but on the street it was the best, the q-jet lacks the power but never stalls and works great and i get killer mileage for a full time 4x4.
I'll take a well built quadrajet anyday. I've had gas pouring out the filler cap & kept putting along. Once you get the float right it makes for good times.
I let people talk me into tbi for my new build, I hope it works out.
I read an article where they put one on a jeep... stood the jeep on the back spare tire straight up in the air.. it still ran..... then they laid it on its side and still ran.. supposedly all flops were by accident..
that article is the one that changed my mind from a qjet to avenger...
x2 on that one...
out of the box the truck avenger has issues... need the accelerator pump cams kit... put the biggest one on this weekend..... the black one..
now my off the line stumble is almost gone.... a bit more tuneing and will be good...
I didn't vote because of two things one the low throttle response of a quad is much better than either. Mileage. I have two freinds with truck avengers, after much tuning they both run great. Lost 2 mpg to the quads they were both running before. The holly seems to pull harder on the top. I have tried all the little tricks with the edelbrocks on 5 or 6 different rigs. They all ran good none of them ran great. Its hard to find a good q jet guy but I personally think the q jet is the better carb of all of them, they are just way harder to work on
You can adjust a Holley so its not all top end power. It is all in the float bowls. When you change the float level you actually change the fuel curve so you need to find that sweet spot between all out see of your pants top end power and low end testicle desending power.
Im running a Holly TA in my Jimmy and after the initial install/adjustments it has ran fine with no other adjustments needed..
Not to hijack the thread, but wishbone ur blazer looks exactly like mine. And im in Oklahoma as well....hehe.
Cool, I'm in the Okc area so if you see me around stop and and say hi.
