Boiling Fuel

[GBowman]

I bought the Coolcarb spacer, worked perfect.

I will just post my experience....go figure


*I have a KC 427 with a 112 LSA cam with duration in the 250-260's. I have the idle set at about 1050-1200 and the carb is a QF-750-SS with the choke. I never open my hood when I park and the thing cranks all the time.....even in the middle of summer it handles traffic fine.....haven't ever had it buck, spit ect.

*A local friend of mine has the same fuel pump same fuel line runs ect. He runs a KC 445 Windsor with 108 LSA cam with slightly more duration than me. His carb is a QF-850 no choke, I know he runs a heat shield under the carb and maybe a spacer. The only other difference is he runs a larger oval air clearer. The hood on his car always had to be popped when he parks and he has had the car bucks and spit in warmer weather.

Can't remember who sold this as a pack (Jegs has it under their brand), but I used just the 1/8" spacer with a gasket on both sides for all of my BB Cobra's

I used the small spacer with a gasket on both sides, raises the carb a little less than 1/4" with both gaskets and the smaller 1/8" heat shield

That looks like the Mr. Gasket insulator kit. I bought two of them for my dual quad intake and modified them to work. Definitely some improvement.

Probably, only I did not use the larger, bottom heat shield, just the heat shields between the two gaskets. Worked on everything, even the 427 Tunnelport powered ERA (188) with twin 600's on it and the old style radiator. Before their installation it was a nightmare to drive in any temps above 80.....Afterwards, I could drive it in temps of 100 with high humidity and not have the fuel boil in the bowls.
