Help help me build my motor!

Hey i need some serious help I have had a 73 duster for a year now and I'm finnaly ready for the motor build just one problem I cant figure out a good combo please help!!

I was considering a 360 (I already have one so why not) with 10 to 1 compression a MP .509 cam, for the heads i know a guy that owns a cylinder head shop so im taken care of in that department what intake do u suggest and what size carb. Im not commited to any combo yet so any suggestions will be appreciated. If I go with the combo mentioned above what stall speed do i need and would u consider this a streetable combo?

Edelbrock Performer Dual plane Will give lots of bottom end torque.---650 Holley ---10 or 11" converter will get it going pretty quick.----Good Luck!

More street than strip? I'd go with 98Durango5.9. The RPM and a Demon. Since the Demon flows better than the rating and the RPM is the best dual plane out there, it's a winner hands down.
More strip? Step up in carb size, same intake.
I have 4.10's in my '73 Cuda. Not exactly hi-way, but doable. (Read sig) This combo is good for mid to low 12's depending on weight, weight transfer and state of tune.

Forgot to add how well the traction is.

The purple cam is a good base line cam. There are many manufactures out there. A custom cam is only a couple of dollors more and will out perform the purple well. Talk to the grinder themselfs and have all the engine, trans, car set up info ready to answer a small set of questions so the grinder knows exactly where he stands.
This way you get the best performance from the new cam. More info the better.
