As many may have heard, Holley injectors may have problems handling fuel pressures above 17-18 PSI.

I had the chance to assist in a 2bbl Holley TBI kit install (from howell-efi)the other day and noticed that the style of the injectors have changed. I dont know if they corrected all of their problems as the only real visual cue is the difference in the way the wiring harness plugs into the injectors. They now use a sort of weather pack connector (like the rest of the plugs on our cars) instead of the old cap style plugs.

cool. Your engine is 5.9L? thats awesome. Is it true .060 over engines have cooling problems or is that a myth?

Its 360 ci. Havent had any cooling problems.

 

You shouldn't have cooling problems. The problem is that if you let it overheat the block is a lot more likely to crack if you have thinner cylinder walls.
