340 Vs 360
If built similar, the 360 will flat out kick the 340 in the nads. This is assuming similar cam specs, compression..etc. The longer stroke provides more low end torque on the street which is what you want. The 340 has the respect and mojo factor but who cares about that bs?
The 340 is legendary for sure but they are not worth what people price them for. More power for your money with a 360.
The neighbor beside me says, you'll never get respect with your built 318 and 360 stuff. Told him that I didn't care, because when my car runs the number, it tends to shut people up. 360's are very easy to make power with and I'd only buy a 340 if it was real cheap.
