100% agree. Make all the torque you can. If it were me I'd save my penny's and buy a $350 cast 4" strokes crank. In the grand scheme of things it will be the best bang for your buck. And who really wants a cast crank 340 motor? Might not be worth as much as you think.



This was pretty much my thoughts.

I would advertise the 73' 340. If I could make the sale for a decent amount of money, go for it. Otherwise your 340 is just as easy to do a 4" crank on as anything else, if you wanted to. That car could really use something with a 4" stroke crank. The smaller mains are good for high RPM if you ever decided to do so. In your case probably no difference whatsoever between the 340 block and 360. If you do not plan on installing a crank the 360 comes with more stroke which would make the choice to go 360. Just depends on your abilities, money and desires.
