When someone asks how many ponies (every stop) you have an answer instead of a guessing game.

Where are you located? Maybe someone on here could shed some light on a shop that dynos that you weren't aware of. 500$ is the going rate here also. Especially an engine that is relatively mild (no huffer, ect)

Might be worth asking around. And yes I agree with what's said above, the money spent will be well worth it. You'll know exactly what you have and that it runs as it should.

Be careful what you wish for.
You'd then want superchargers, intercoolers, and bigger drives too. :D

Run it on a stand to make sure timing is all set, no water/fuel/ oil leaks...then if you are uncomfortable with your tuning abilit and/or want to save money by zeroing in on prop choice needed...bring it to a dyno.

Nothing worse and more expensive then putting a motor on a dyno that has some sort of problem like leaks or etc that requires time or tear down.

Where are you located ? Maybe someone knows of a good dyno shop that will help tune and not charge you a ton.

Edit in: Be forewarned, some dyno shops will get you a power # that's not correct and won't help you tune...which turns into a big waste of money.

can you do all the same tuning on the stand?
Dyno time around here is very expensive but run on an engine stand is much cheaper

if by rebuilt you mean a refresh like bore job with same compression pistons,same cam,valve job ,rings&bearings,timing set than a run stand will probibally do the job but if compression ratio,cam or heads,induction system were changed a dyno is a good tool to help sorting the tune.just my humble opinion.

New pistons bore 30 over new cam new bearings nw valves and springs

So how much more power is made at an AFR of 12.8 on a dyno compared to an AFR of 12.8 in a boat if same exhaust/setup is used?
Just curious
