Edelbrock 800cfm AVS2
The ST Demon... i always heard TQs were amazing IF you could get them to work.. and IF you can keep them from leaking.. i spent hours today learning bout different carbs and i like that the ST is a re-design and not just a copy
Cool man cool!
The TQ, being old these days, can be a hit or miss on the quality of the carb. Figure the best are the early non emission models from ‘71-‘74-ish area except truck models which have less vacuum hook ups on them since they were exempt from what cars had to put up with. That’s a lot of time!
Throttle shafts wear out but are fixable with a bushing. The main body, if available these days from Tomco, can show there short comings with to much heat applied to them, which, back in the day, in order to meet the restrictive tail pipe requirements, the factories raised the engine operating temps upwards with thermostats @195*’s. Add in summer heat.. the phenolic resin would crack under the heat.
Rule #1 w/a TQ, keep it cool, cool as possible, start with that very thick gasket the factory used!
I’ve had one warp on me and one crack. No other issues through their usage with me.
Once you have a good one, no cracks or warpage & good throttle shafts, etc…. Like any carb should be…. Their learning curve isn’t to bad. They’re different in a sense and not different.
and seems like a great idea all around. Time will tell.. be a few months still. I will be taking it apart and checking everything beforehand for sure though.
It's in my cart at Speedway, a 750CFM with the composite body + Aircleaner setup which i needed anyway for $536 shipped.. which is much less than other carbs i had looked at.
I agree. Looks and seems like a great idea. Though I’m not a fan of having to remove the carb in order to change jets. But I guess there’s a caveat to everything!
Good move on the composite body.
