holley or edelbrock?

i've always heard good and bad about holley's, esp for the backfireing that they don't take it to kindly, but on the flip side edelbrock i've heard nothing on. my carb is too small for my new windsor according to atk and when i do replace it i'm wanting to know who is better.

For your 84 351W I would suggest a 600-650 cfm carb for a stock motor. The Edelbrock #1405 is a good choice for a carb with a manual choke, or the #1406 with the electric choke. You'll need a bracket kit for the kickdown linkage if you have a C-6 tranny. The factory carb on the 84 351W H.O. is a Holley #4180 600 cfm, elec. choke. You can gete a reman unit for about $300 and hook it up without any added brackets. Based on my experience with these two brands of carbs, I much prefer the Edelbrock 1405. You can also read up onthe thread about other Holley carbs, like the Truck Avenger if you plan to offroad alot. the TA lists for $425 at JEG's or Summit, JSM84

i can probably get you a barely used holley 650 that came off a 460.

ive got a edelbrock qjet on my camaro and supposedly they are harder to tune than the holleys. ive never heard any troubles with backfires though.

I would put a Edelbrock 600cfm 1405 on it if your just lookin to replace yours. If you plan on offroadin it alot Holley has the 670cfm Truck Avenger, and Edelbrock has a 650cfm Thunder Series AVS offroad. You can get both of them at from Summit Racing, there both awesome but from what ive heard the Holleys better but cost more. Ive driven truck with a Truck Avenger and there pretty bada$$, never even seen the AVS offroad though.

Oh wow, this thing just seems to *never* go away does it ?

Do yourself a favor and take a stroll thru the archives. This is a common & contentious subject. This thread is the most recent & ongoing in case you missed it : http://broncozone.com/forums/index.php?sho...+edelbrock+carb

Just to quickly recap, the Edelbrock is just a chromed Carter, they purchased the rights to the Carter carb then chromed it and slapped the Edelbrock tag on it. Hollys CAN be made to work but right out of the box they're setup for street/strip cars and NOT trucks. You *can* make a Holley work well off-road but you have to invest in a few kits like the dual-float thing. They don't handle off-camber situations well and a single backfire thru the carb usually blows the power-valve. These are all thigns that can be overcome but you have to invest time & $$ into doing so. IF you're looking to get people throttling each other over which carb is better this is an *excellent* question to ask.

The sad but true fact of the matter is that an EFI system is probably the best way to go. The Factory EFI systems are fairly complex and can be difficult to retrofit but something relatively simple like the Holly Pro-Jection gives you an EFI throttle-body that will work with your existing intake. You get 90% of the EFI benefits (milage, power, reliabilty) with very few of the drawbacks (lots of electronice & difficult to retrofit & diagnose).

Granted this is just an opinion & it's nothing more than *my* opinion at that but there it is.

If it were *my* truck I'd save a bit more and run a 2bbl Projection instead. The milage, drivability & milage will increase without adding so many new parts that the system becomes difficult to diagnose when problems arise.
