So it is a KB 1.8 L blower with 6 psi pulley. Saw the dyno sheet and it made 443 at 6300 and 458 at 4200. I don't know what is done internally and it doesn't lope a lot at idle I am so confused at y it is making the numbers it is at such a low psi with not intercooler. Please help....

Are you observing 6psi? Also verify the gauge is reading right by comparing with another gauge. Making peak hp at 6300 is pretty darn high considering you would be shifting a few 100rpms after. That seems more like a 4.6l than an old push rod 5.0. Any info on the heads being used?

Trick flow I believe. But I am starting to think it is a 331 and it is all forge scat internals and it falls off at 6500 really quick. I believe the injectors are 50+ lbs

to your initial question

'cause dyno numbers can be totally falsified.

especially if you want to sell the car......
