72 340 build vs...other options

Ah the cam, makes sense in the smog era.- Yes I believe the later 340s... the smog era killed them its actually a shame. But the 340 I beleive is easily moddable for the racer working at home the parts interchangeability I like the full floating pistons makes piston swaps easy etc.

My stock 1973 H code Ralley Challenger ran well. it took upgrades as any other 340 would. keep in mind 1971 340 rated at 275 was gross and 1972 was net with assy if ya did not know what net was. keep in mind both years had the same cam in the 340s. it did not loose that much HP with just lower compression. It was gross vs net
yes cast crank but worked fine until i rebuilded it with a steel crank, and heavy forged TRW pistons.
