340 or 360?
English comprehension? Pay attention now...
Build a 360 as a 340 and the 360 runs away from the 340
It's not rocket science to build a 360 faster than a 340 and it may cost less. They look the same installed so no one knows...
9:1 compression 2.02 heads, 340 style 1968 cam specs, 340 exhaust manifolds, thermoquad on a cast iron intake, proper torque converter if it is an automatic.
I may have built an engine or 2 like this....
