Today, dollar for dollar, is the 318 faster than the 340 ???

I think the original parameters of the test were sufficiently narrow to produce responses in the desired direction, promoting 318 builds.
Thats a lousy way to do a scientific test..... but this is an opinion piece! It sure got lots of opinions.
Even though ive never built a small block, never had one except for the 273 i have now, i still find this thread very entertaining.
I seriously doubt i would build a 318 or a 340 for my 67 barracuda.
I agree about the original parameters. As I previously mentioned say someone scored a good condition stock 340 ,did some tuning nd pulled 340 HP on a dyno.

Can 318 guy pull the same HP? with the 3 grand. I think we've found out yes possibly but not with LA heads or at least that was my conclusion. And this is pure bench racing it would have to be played out for real on a dyno. 273 will run real good for you.
