ok guys. we have been tyring and tryin to get my motor running right, thanks to ryoken (paul).

the motor is a 350 bored .30 over with a 501 lift cam. we have been trying to get a regular roch quadrajet from a 305 running on it, but we cant seem to get it just right.

what do you guys suggest for a carb for that set up?

edelbrock 650? holley?

thanks

tom
 
A few questions first, what is the intended use for this truck ??? Mud, rocks, racing ??? For playing in the rocks where you get off at some crazy angles, I'd say a Q-jet, but if you'll be blastin' through the mud pits, then I'd go with a Demon carb, like a 650cfm Speed Demon. /forums/images/graemlins/deal.gif
 
I love my 650 EBrock off road. Never used it off road yet though. Cheap too.

QUADRAJET... for a few reasons
1-spread bore helps MPG because it only has 200CFM primarays(what you will use most of the time on the street) and when you open her up you have another 500CFM dumping into your motor which I like
2- can flood them out
3- there a great carb and is PLENTY for you motor(from what you said about it)
I have a quadra jet on my "not excally stock 350" and it runs great I did change it out with a eledbrock 750 but HATED it I drove mabe 3miles with it before I went back to my old q-jet. Even after I got it tuned my truck ran SO much better with the q-jet /forums/images/graemlins/waytogo.gif
 
so a reg rochester quadrajet from a 350 should work fine???

i would love to go that route since we have one!!
 
I would use a Q-jet.

Edelbrock carbs hate big cams without extensive tuning so be ready to mess with it or it'll never run right and it will run rich and foul plugs a LOT.

If you're up for that the Edelbrock carb is ok, but it SUCKS for angles. See my RTC post. The trail run I was on with that carb was so bad people have doubted my ability to compete in RTC, thank GOD that carb is LONNNNNNNNNG gone off my rig.
 
The Q-Jet would be a great choice! If you have the engine spec's, you can have it set up at a good carb shop. Usually once a Q-Jet is set, it stays that way for a long time. The Edelbrock carbs use more fuel and need more attention. /forums/images/graemlins/peace.gif
 
I run a Holley Truck avenger and I love it! Never stalled out one me once! /forums/images/graemlins/woot.gif I would buy it again.
 
Q-jet.....I just picked up a rebuilt one from Autozone for $124. It is too damn hot here to rebuild it myself. The wife won't let me do it in the kitchen.
