| Im looking into changing out carbs. Im not happy with the stock q-jet and thinking of edlebrock. How much difference is there between a 600 and 650 cfm? Should I spend the extra money for the thunder series or stick with the performer which is $100 less. See everyone at Big Al's this weekend. | |

| Here's the difference's between EDELBROCK's Performer & Thunder series carbs: -The Performers come in 600 or 750 cfm, non adjustable secondaries. -The Thunders come in 650 or 800 cfm, have adjustable secondaries and some cosmetic differences. Back in the day CARTER put out a chart that claimed a perfectly running small block chevy could only effectively use around 650 cfm. I doubt you will notice much of a difference between the two. Most people dont need adjustable secondaries. Most 4x4 guys will tell you that a Q-Jet is better for hill climbing and off-angle use, but thats only if its in good running condition. Most original GM Q-Jets are getting really old and becoming un-rebuildable. If you go EDELBROCK, I would recomend you upgrade to the OFFROAD needle and seat kit and definitely dont be affraid to take the top off and spend some time adjusting the floats. ~John | |

| I think John would be the one who would know the difference... he sells them and probably has to know the difference because he gets that question often! BTW John- thanks for getting all that stuff in one pile for easier quicker shopping for me so I didn't have to wait for them to look up each part and possibly forget something. As it was, I forgot to add that I wanted a thermostat and housing...but I got that now. Now I am stumped on brackets for my BBC... I got a lower alternator bracket and a lower PS bracket... but need the top ones! I might end up having to order your chromie kit unless you have it is stock. | |

| Is there another carb out there that would be better? Supposedly the Thunder is the best on the market but it seems everyone says their brands the best. | |

| I have heard a lot of good things about the Holley Truck Avenger... but no personal experience since I am a small dollar guy! | |

| We get a lot of positive feedback on the Truck Avenger for all around 4x4 use. They aren't cheap. We (General Store Auto Parts) are still selling it for $399, but that wont last long. Prices are going nuts. Summit is already up to $426 plus handling on it. Its a 670 cfm unit w/electric choke (#0-90670). If you're just bogging and not side hilling and climbing you cant beat an old-school Holley double pumper for straight line pure performance. You can save a little money by getting a factory re-man unit. We sell a 650 DP re-manufactured for $318.99, same as Summit but w/o the handling fee. ~John | |

| I've looked at those too. Been wondering if it would work good with the Edlebrock torker II intake manifold I bought. I haven't installed it yet because I don't want to be moved up a class. Am I going to see much improvement or should I just start building a new engine this winter? I kinda like what I hear about the 383. | |

| well if you ask me... $318 for the Holley and $399 for the Avenger... you are tossing out $300+ out of your pocket whichever you decide on. I would suggest the better carb even if you are only planning on straight line racing... the extra $81 you are spending is so litlte compared to how much is coming out of your pocket already. If you buy the $318 carb and decide to upgrade to the $399 carb that will soon be $426... that is nearly $800 out of your pocket after sales tax and gaskets! Buy the best part the first time if you are gonna spend the money. Wish I always followed this advice myself! | |

| I guess if you already bought the edelbrock go out and spring for the available offroad kit for it too. It is not that expensive . As crummy as those carbs' are in off camber situations this should help some. | |

| THe spring kit will also help with bouncy conditions too. I was going down hill over some rocks with the local IH club, and the Brown Trout kept wanting to die on me every time I suddenly dropped the nose off a rock. Inertia would keep the floats up, and the carb would thing it was full, thus starving itself. | |
