Step Right Up and Guess... What will my 410ci make for Power?

What altitude are you at? Too close or under 3,000' and pump gas will start to become a question...maybe you're already planning for that? I know you said you did some work on the intake, but a small single plane (Torker II on street, Victor if more track duty) will let that new cam breath a lot better. Also, you didn't mention spring upgrade-stock Brocks will probably let the valves hover with that new solid. Stiffer, correct length pushrods were included too, ya? All that being said, hoping you can end up 25-ish better (or more!) than what you had. Only important thing about the dyno really is that you're using the same one from last time...SAE correction factor will cover the air discrepancies. Don't forget to send your printout to your converter folks so they can "reprogram" it to your liking. Can't wait to hear how wrong we all are:lol::popcorn:

Elevation is about 1k but it won't be an issue. The engine builder who did all these upgrades took everything into account. When it comes to building Mopar engine's he's the only one I trust. He won the very first Mopar Performance engine builder challenge in 2006 for his 440 ci 700+ hp small block. He's built a half dozen engines for various cars my dad and I have had. I didn't go into all the details about what he did and put into the engine but it got a full work over with new valve springs, retainers, locks, pushrods, geometry correction on the valvetrain, valve job, pocket porting, matching the intake and cylinder head runners etc along with the other work for swapping out the cam. This wasn't a cheap little cam swap I had done lol.

I drive a stick so no reprogramming needed on a stall convertor ;).

This thread really is just for fun to see how close people can get to the right number. My estimate being it'll be on the same dyno it was on before and it made 496 hp previously makes me think it'll probably make about 536-540 but we'll see in a few weeks.
