I have no issue with ethier carb and have used both a number of times with sucess. So, between the 2 carbs, my vote goes to the Thermo Quad and heres why;
Thermoquad....
most people are scared to work on a TQ, because they don't know anything
about them, terribly easy.
unless it's cracked, you can rebuild it for the price of a kit.--$30-40.00?
"the bog", you can fix that in the time it took you to read this thread.
Like Mr. Bill said above, most every TQ I have picked up was $20 - $50 carb. A rebuild kit is under $40. In learning the carb and rebuilding it yourself with an added cost of a soulution to dip it in, a garden hose to rinse it off, compressed air to dry it and blow the passages clean and a gasket scraper, you can do other peoples carbs right quick for a recap of dough.
The T-Q does have a bunch of finer points to adjust. It's a royal pain the first time you do it and just a simple pain when your on the hundreth carb. But once done, it will operate fine.
The "BOG" is due to several possibilties if not a couple acting out at once. Any carb can have this issue. On a T-Q, the secondary side can open up to quick and cause this. Something other carbs do not allways suffer from.
With the small primaries and large secondaries this carb is a good street choice. You will have excellent low end throttle response with very good top end power.
My choice...the Thermoquad!
Part of Rob's post is the reason I looked into this carb.The smaller primaries will lend themselfs to excellent throttle response and high velocity for better fuel atomization. Finer fuel atomizing means the the fuel is more in a mist state which burns more completely. Which equals mileage and power due to the complete fuel burn. Of course, an ill tuned carb of any sytle will get poor mileage and run like crap. So you'll need to take the time to get it right. This is a bit more of a pain with a T-Q since they do not come apart to tune so easy.
Small mileage getter primary side with excellent throttle response, big secondary side for that MoPar "HOWL" while getting the cfm's needed to feed a monster.
Thermoquads are not overly complicated but if you have not rebuilt or modified one before get someone with a working knowledge of this carb to lend a hand.
Early Thermquads 72 to 75 are the most tuneable but others will work well also.
Agreed!
The T-Q is an excellent street or street/strip carb
The biggest secret is learning them, setting them up correctly and the final thing is keep the heat away from them.
