Firstly, G'day to all, I've just found this site and registered (couldn't help myself).
Got a P6 LTD 351C with the infamous Carter Thermoquad stock setup. I've also got one sitting in the shed as a spare and was thinking of a dual carb setup. Is this feasible, if so where are the manifolds easily available.
Main reason for wanting to use dual carbs is for some gain in power, wanting to build a warm street motor around 400hp, and for something different with looks etc. You are probably right in regards to practicality, but I get an idea stuck in my head and it's there til a better one comes along.
so you want to run 2 carter carbs on a street engine, hmmm crazyness especially when you consider that the thermoquad is rated at like 650 or 700cfm you would be better off running a larger single carb and manifold, if you want the looks go for a funnelweb manifold, i know of a car that runs a tunnel ram manifold with 2 465 holleys and its fairly streetable, but its only in a 1000kg car

Creativity and individulaity are one thing, but some things work and some things don't when it comes to cars.
There's some great tech tips on this site on clevo combo's that work, suggest you have a good read and take the common denominators.
It all sounds so nice. I'll tell the missus that the kids aren't going to school next year so I can get the Limo bombed, lol. Speaking to a mechanic, he was telling me that the thermoquads can be set up to the equivalent of a 980 Holley. Comments?

He could be right, I'm sure out of the box they are 870cfm approx.
Hello DMax.
The original Thermoquads were put on big block Chrysler motors i.e. 440's in the early 1970's. They had a flow rate of 800-900 cfm if I remember correctly. You could seek out some contacts in the US who sell kits to rejet and calibrate these carbies. There are some enthusiasts who may be able to help you find the parts you need. Try a google search.
Cheers
