I received the dyno sheets from dyno tune after my cam install. car is a 93 LT1 with these mods:
3.54 gears
2800 stall converter
shorty headers
modified stock air box
Resonator delete with X-Pipe
Muffler delete's
first dyno run was done in this trim^^^^^
added:
Custom grind Lunati cam
Lunati Voodoo 1.6 roller rockers
Comp Cams Hi Tech pushrods
second dyno results were with these upgrades^^^
video before cam
So you lost basically nothing on the bottom and picked up on top? That's damn good. What were your cam specs again? I wanna say mid 220s @.05? If I had to guess that is around 400 chp?

If you ever see a ratty/ghetto cruiser pickup towing a 67 bird down there, it's me. Freaking E-town lol.
cool. hopefully we run into each other sometime. I try to get there a lot. I have been working a bunch of ot so not as much as I like. only ran once since tune and had issues. car immediately flopped on face after launch. I have learned these things have common issue with fuel sloshing to rear of tank when below 1/2 tank starving pump. so I hope that was the problem. trying again Friday with full tank. I also changed pump screen.
you can see in this video it flopping.
I'm really impressed you found somebody that will dyno tune these OBD1 dinosaurs. You have the same tach problem I had a while ago. It was running into no man's land after 6k. I had to install an aftermarket tach.

Yea I have plans for one eventually. or maybe a shift light
Nice results. I’m considering a similar setup. I am about to swap a D44 with 3.45s into my otherwise stone stock 93 auto. Cam will be next.
Do you have to shift manually with the 4L60 to enjoy that extra 750 RPM from stock? You have to dig into a 700R4/4L60 (non-E) to change the shift points with different springs/weights I thought.
Also, while you were in there did you do a water pump and opti? I’m for sure doing a new pump but am inclined to leave a functioning low mileage factory opti alone.

My bad actually, thought it started at 2k. There is a big crack in my phone screen though so that's my excuse!
