Depends on what it is(how involved the installation is), but the least you’d pay nowadays here is $550 per session.
Keep in mind, most of the time when it comes to this, the owner as already spent a pile of money and numerous wasted trips to the track trying to get the cars performance to improve. The system they’ve been using to make decisions on how or what to try next hasn’t been working for them....... so they’re looking for a different approach.
It’s no different than someone bringing you some ported heads and asking if you can make them any better. You’d flow them before you started working on them, right?

Absolutely but I didn’t charge for flowbench testing unless it was someone walking in off the street. Then it was 50.00 but then again maybe this is why I totally gave up doing work for others. Lol I kinda figured 400-500 for a dyno session

A lot of the time when a cars performance is off, the first thing that gets blamed is the motor for not making enough power. It’s usually when it’s not a “known good” combo, and/or has never been on the dyno. In that situation you don’t really know what it “should” run. If you have a bunch of 700hp parts, and your motor makes 700hp...... you’re doing okay.
One thing to keep in mind is, many combos don’t have another “easy” or cost effective 50hp in them. The pre-disassembly dyno test can save them a bunch of money if the motor combo is already nearly maxed out. Going from that 700hp to 750hp might require new heads, more cubes, a better block, etc.
Sometimes that next 25-50hp is way beyond what their budget is....... and what money they can spend would often be better spent on other areas, if the car isn’t running numbers that equate to what the motor is making for power.
In a situation like where the OP is at now, dyno testing the motor is part of the diagnostic process. Just like when your “check engine” light in the dash comes on. You can hook the scan tool up to it............. or start swapping out parts hoping the light will go out.

Id put the jets back to last year. then check Cam degree! Checking that the cam is installed properly is easy and can be done in the car. I had one where everything was installed correctly but was way off from where it should have been.

Could my msd box going bad cause bad performance. I think it just took a crap on me today .. Sure can. It will throw you a curve ball for sure. Most people think the ignition either works or it doesn't. I've found that isn't correct. Even with a mag.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Well I just pulled the motor for the 4th time this season and I can tell you it’s getting old pulling a B.B. out of an a-body. I noticed that the exhaust looks all sooted up. I think I have my carb space on backwards so not sure what that will do. Then I got busted tell on my converter and can’t seem to find anyone to fix it so I Guess I will weld them up and try it all again. I don’t know what else to do ??? John have you tried Quickdraw converters? Lots of guys use them. I can also hook you up with a friend that works at Perfect converter company, several fast local guys use them. The guy lives around the block from me(Bubba).1-440-232-9677

I seem to be having trouble keeping up with what’s going on...... You’re trying to get it to fire........ but you said: I just pulled the motor for the 4th time The right way to test the box is with an MSD ignition tester.
