Was 84 the last year for a thermoquad ?

Im sure its been asked before, but I cant find any threads on it.

Is there any late model MPI intake manifolds that will fit ( or modify to fit)a 340 motor? I want to run EFI, but dont want to pay the high prices of aftermarket units.

Thanks guys.

Hi guys i just made a short vid where you can see that my fuel pressure gauge is shacking, before i had one from allstar with glycerin and the one died now i have one from russel performance but its the same thing, could it be that i have some leaks up the lines? My car drive good without any problems, just wanna fix that

Thx Peter

while driving and there is hesitation , car still goes , but it takes a bit until the secondaries open , does this mean it needs the lighter spring in the vacuum secondaries diaphragm housing , or is there some other adjustment .
