new 406 pontiac finally finished

Wow, a 67' with a Torker. Staight outta the 60's man. And I see you did your homework, Pontiac 670 heads (and most all) max out at .450 lift any more just stresses the valve springs. Good build.

Did I miss the 670 part?
What are the rest of the cam specs?
Needs more carb.
I don't think you are going to be able to run pump gas.
More details needed, I don't want you to hurt the motor.

I was guessing stock 4 barrel heads. YC is a 2 or 4 barrel motor? Yeah, those closed chambers want high octane. EDIT- I'm seeing YC is a big car motor, 2 barrel, small valves, 10.5 comp. Any head work done?

I would think the carb would be good to 5600 or more. Flat tops and those heads = high comp.!
I like the poncho motor too. Gives people something to talk about

Have you ever thought about going with a properly setup q-jet? I think it would give you the best of both worlds.

heard the q-jet was the best ticket but know very little about them other than how take em off and put on my holley :lol: my spread bore holley has been on all my old circle track cars( limited late model, streetstock,superstock and open wheel modified) and it is really reliable I will see how it goes in feb for our first test and tune , the car should be up and running by the weekend
thanks

Here's the real question:
What are all those Oregon hippies gonna think of that rowdy hot rod?
