Hello Everyone,

I am currently in the process of putting together all the parts to take my 1971 360 block and punch it out to 408ci for my '71 Duster. The goal with the car is to make 500hp. Here's what I'm looking at doing thus far, but I'd like to get some input on the best streetable/hydraulic cam for the build along with any mopar-centric head porters in SoCal.

408 stroker kit - 10.5:1 compression:
SCAT 9-360-4000-6123-2125 Cast Crankshaft
SCAT 2-ICR6123-2124-7/16 or Eagle SIR6123CB (I-Beam rods)
Icon Forged Pistons #IC744-030 (4.030")

Speedmaster 65cc Bare Aluminum Heads

Not sure on roller cam - need suggestions

Edelbrock Air Gap manifold

Holley 750 Double Pumper

Doug's SB Headers - Looking for something used

Milodon Road Race 7qt Pan

Suggestions for rockers?

My budget on this build is ~$4000 because I also need to sort out some suspension issues on the car, as well. If you have any suggestions on anything listed or any of these parts kicking around, please post here or PM me.

Thanks,

Durs
