fuel pressure test 1997 chevy silverado 350 5.7L
Misfiring pretty bad. I get P0300 if I make it misfire for a bit. I'm assuming my poppets have gone bad and I should upgrade to MPFI. What do you guys think?
Edit: Lack of power/Hesitation on acceleration. If I try to go fast, RPMs just go up until I let off the gas then it'll give me a little power. Basically I can only accelerate slowly.

I don't see a problem. Run a volume test too - 1/2 pint in 30 seconds.
If the engine was running lean enough to cause a misfire I think you would also have other drivabilty issues like a loss in power too.

Sorry there is drivability issues too. Hesitation on acceleration basically. Like if I floor it RPMs go up until I let off the pedal. Basically I can only go anywhere if I apply light gas. I'll update original post with more information.
