To many stories etc on sizes, some state 600cfm, 730cfm, 800 and 850, who bloody knows, all I can tell you is they are one of the best production carbies ever made if in good order and setup right, far better than a Holley straight out of the factory.
But I don't recommend to use them with LPG, cold petrol and hot plastic when switching back to petrol can cause them to crack. |

| they are not that hard to rebuild, I have done 1 years ago but the only suggestion is that you take it apart slowly so you can see where everything came from and have a exploded view diagram of the carby. |

I believe in Australia we only used the 750cfm version. There was an 850cfm factory version in the US as well as a 1000cfm aftermarket version.
They are not that hard a carby to rebuild, its just that a Holley is so easy to rebuild!! Also in comparison a Holley is a very basic carby in function. |

| I have found that whenever I have rebuilt one I always used to replace the floats as they are plastic and start to soak up fuel as they get some age on them. |

I have been told stories about factory brass ones collapsing by a mate that used to rebuild them all the time in a performance workshop, his preference is good plastic ones but he mentioned of heaps of float failures.
This bloke is a Chevy man but loves Thermoquads over any other 4 barrel carby, he can show anyone how cheap it is to get over 225rwhp with good idle and economy on a XC-XE based 351, using only the factory carby (rejetted and tunned), intake, headers, sports exhaust, re-graphed dissy and certain spec cam, as long as the engine is in good condition, it isn't big hp but it is reliable and good economy for a Cleveland, he reckons they can get 25mpg out of them
I find the glued on jet caps often leak, bastards of things to seal, this causes engine flooding and destroys those cheap a*** Fuel-miser throttle plate gaskets. |
