340 vs. 360

Well Mike, for me, it's like this;

Why spend the extra money on a 340 block when the 360 is cheaper, in J-yards?
For a street strip engine, I think a 360 is a no-brainer. Heres why;
1 Like said, cheap junk yard finds.
2 Some are roller cammed blocks.
3 The longer stroke is an advantage because it produces more torque down low. It also brings in peak power and torque sooner because of it. The heavier street car can use this to it's advantage due to it's extra heft.
4 If you wish to internally balance the engine, you can. Parts like the flywheel/torque converter and damper are an easy get.
Though theres no huge advantage to having the engine internally balanced for such an engine, it does make converter changes easier. The cost is minimal and off the shelf.
