New engine problem!!!!
I installed the FMS crate engine (M-6007-XE3M) and it sounds great but i have a problem. It reacts fine and starts up okay but i cant sit at a stoplight....it just dies. It feels like a have NO vaccum. And because of the lack of vaccum, my brakes feel VERY stiff. Ive been through ALOT of mechanics and most of them say" I cant understand it". We all checked the vac. lines, leaks, etc etc. I'll give u a list of the extra stuff i added to the crate engine:
Trickflow intake and spacer, Trickflow 70mm t/b, bbk headers, bbk cai, bbk fuel reg, bbk, o/r exhaust, 93' cobra 70mm MAF, 24lbs inj, MSD distributor w/ crane cams ignition box and coil, and SCT custom chip for the mods.
And one thing that may be a factor is FMS said "when dropping this engine into a 79-93 foxbody make sure u use this conversion kit". It has a timing pointer, crankshaft damper, reverse rotation water pump, oil pan and thats about it. I never bought this kit. Maybe that will fix my problem, but i dont think that will have anything to do with VACCUM. So with these mods, i cant understand whats up!!!. If anyone can help it will be GREATLY appreciated. Any ideas???

RE: New engine problem!!!!
if the brake pedal is really stiff then you definately dont have any vacuum, or unadequate vacuum. put a guage on it. should be around 17-20 at idle. how does it idle, with a leak big enough to affect the brake booster it should be a huge leak, you should be able to find it with some starting fluid. just put a vacuum gauge on it, or have someone do it for you, that will be the problem.
