4" Eagle stroker crank from Mancini(do have it checked) KB stroker pistons. the boneyard block/rods will work as will the 273 rockers/340 HP ex manifolds. Not sure if the single plane torker2 would be good and I love dual quad setups. Might do a generous bowl hog on the j heads being carefull not to touch the seats(I'm reading that they are already to go).

if it were me for a street motor, I'd probably use the KB dished pistons, and a cast crank, have it externally balanced to 360 specs to save some cash. should end up with about 9.25:1 compression using the thin Mr gasket head gaskets. flat tops, you're looking at 10.75-11:1 depending on head gasket.
cam, for a hydraulic, I'd use a lunati voodoo 60303. mechanical, I'm thinking the MP .528" cam or maybe a comp XS274S. with the higher compression, you'd need to go larger on the cam if you want to run pump gas, which will pull the powerband higher in the rev range, and not make it as street friendly.
intake, I'd get rid of both of yours and get an edelbrock air gap or performer RPM.

I'd use an eagle cast crank. They internally balance with no mallory metal. I had one in my FAST duster for a bit and it got me in the 11's with 10.5:1 CR. This was with really reworked J heads and a big solid roller cam. I bought a complete balanced rotating assembly from these guys. http://www.gofaststuff.com/kits.htmlI opted for H beams and SRP forgings when I got mine.

Here is my 340 stroker setup. It was built as a pure street motor, with some room to grow in the future if more power is desired (i.e. heads and cam swap).
340 stroked to 417cu inches 4" forged Eagle crank reconditioned stock rods custom forged venolia pistons 9.5:1 compression ratio stock 'X' 2.02 intake valves (no porting) Mopar performance 484 purple hydralic cam (241 int/241 ext duration, .484/.484 lift 108 LSA) Edelbrock RPM airgap Holley 770 Street Avenger Carb FBO Ignition with custom curve TTI step headers
This engine is in a 70 Cuda with a 4-speed and 3.91 gears and it put out 375RWHP and 484RWTQ on a chassis dyno. That would put it approx. about 425HP and 535TQ at the crank. I should mention that the 375HP was at 5000rpm when the clutch started to slip and they shut down the run. So there is a little more HP in the build then what was measured.
The motor runs strong and is a nice mild reliable build. It also has a nice lope at idle (if you like that sort of thing)
