decobraman,

Desk Top Dyno is a great tool. It allows you to compare different engine combinations against each other. Saves alot of time & money. I wish I would have done that when I was building the engine in one of my other cars. I didn't and it ended up costing me a ton of money!

Do not treat the numbers that DD tells you as the Gosbel though! Sometimes it is very accurate, sometimes not.

If when you are done and really, really, want to know EXACTLY what your engine is producing, have in Dynoed on an ENGINE Dyno.

Chassis Dynos readings vary from Dyno to Dyno, even from the same manufacturer. They are a tuning tool, and are excellent for that purpose. The rule when using a Chassis Dyno to see how a change (cam, Carb, etc) effects an engine is to always use the same Dyno.
Good luck and take your time.
