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

If something measures good and in spec, I run it.

Me ^^^^ that's how I roll. For a basic 350 horsepower motor people think you got to have each piston fitted to it's own cylinder, and all the blah blah blah. In other words, in 1968 if you bought a new '68 cuda 340, you should take it off the show room floor and immediately disassemble it. Why ?? Because from the factory......

• batch-ran cam wasn't degreed
• batch ran pistons were thrown into any hole
• green blocks weren't always even
• scabs and snags all over the castings
• batch-run timing chains were used.
• heads varied in CC's

you get the point... yet, folks could buy a new car in that day and drive it 150,000 miles no problem. In fact, they could beat on it for a 100,000 miles. But today, your a bum if you don't do a 2,000 dollar check list to prep a block.
