Q jet base gaskets
 

we have a J/SA ,255hp 69 Chevelle wagon, Does anyone have the part number of the 1/4 inch base gaskets for a Quadura jet ? Thanks

Re: Q jet base gaskets
 

Fel Pro 17845 is one option.

Jegs/Summit has most of the Fel Pro numbers ; I use #1908 .

Also look up Chryco Q'jet base gaskets.

I have always been under the impression that rule book called out "maximum two 1/4" carb base gaskets"? I was told by reputable long time stock racer that its just two gaskets with no specific thickness! Not sure it make any big difference but dose anyone have clarity?

Re: Q jet base gaskets
 

From 2015 Rulebook, "Carburetor heat-insulator-type gaskets prohibited. Maximum of two stock-type gaskets permitted".

Bought theses off Mike Keown many years ago. They are 1/4 inch thick

Jeff, I think that open style gasket is OK for a open plenum intake manifold,, but on a stocker cast manifold, it should be a 4 hole , shouldn't ?

Re: Q jet base gaskets
 

For what its worth, several years ago we tested with the open gasket vs. the 4 hole gasket on the dyno and the 4 hole gasket made slightly more power and torque with our combination.

I forgot about that .... your right

Fel-Pro 1905

If some Quadrajets are like Thermoquads, the thicker, insulator type gaskets are OEM, so 2 should be allowed.


This place has a good selection of stuff for Quadrajets as well as Thermoquads!
