Stroker Cams

Then cam wise I would not go much more than the stock 68-70 340 cam profile. You can maybe benifit from a little more lift, but keep the durration down and stay hydraulic. It should still make decent power and have very good low end torque.

As for the heads. I would do a set of J heads or X iron heads if that is what you have? Go with 2.02 intakes and at least 1.60 ex. Do stainless valves and if you replace the guides you may want to step down to the 5/16 stems for less weight and a little better flow. But with what you are talking I would not waste a lot of $$ on aftermarket heads. Also be very carefull on the compression for the street. Once you bore oversize and the stroker crank with a small cam you will have a bunch of combustion pressure and temp ie heat. So make sure you do maybe a dished Ross 9.5 piston and good head gaskets for the street.

Since you are staying with the iron ex manifolds and 3.23 this makes a lot of since. I also you not go to crazy on a convertor either. You should be in the ball park of the type ot torque a 383 magmum made in the day. So a 11" convertor from say a 69-70 car running a 383 in an A body would be an off the shelf good choice. But if you want a little more call Turbo Action or one of the other companies and tell them what you have and they can give a good reccomendation. Most likely in the 2200-2500 RPM tight style of convertor.

Should be a good street driver.
good luck!
