I have a 89 GT with a 93 cobra motor which was recently rebuilt to a 308
with forged internals. The heads were redone with 202 in. and 195 ex. It
has a 70mm throttle body and egr spacer, gt 40 intake, 24lb injectors, nos
fogger system"not used at the moment", msd billet dist, 6AL, and HVC
blaster coil. When I am at a cruising speed and the engine RPM's are about
2200 it sounds like its missing, but everything in the Ignition system is
new, and I have around 42lbs of fuel pressure. Whats up? Does anybody have
some insight.

Could be the start of your fuel pump going bad. If it happens at low fuel
levels then that would also point to the pump.

Cheers, Rod

What Spark Plugs? Why am I thinking Bosch double plats!

The plugs are Denso uridum "no Bosch in my car".

My car has two fuel pumps, one in take and a Vortec T-Rex pusher pump for
the nitro. Both new, Thanks for trying to help!
