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

I don't have a dog in the hunt with this dumbass argument, but, as I said in an earlier post, Hensley Motorsports has been building 318 4" plus bore crate engines for about thirty years. They do sonic testing and only use those that are thick enough.....and there are some that are thick enough. This has been common knowledge for a long time now.

That said, I kinda agree with your assessment about this thread being somewhat a "fantasy", in fact, I've already said as much talking about the little box he put it in.......BUT, it's HIS box and HIS thread and HIS rules. Let him have fun. I have a slant 6 box. I have fun with that. You have fun (I hope) with what you do.

His point was plainly explained in his first post. Nobody likes everything or every scenario. Even I don't see the sense in some of his boxing in......but damn, it's his hypothetical reality. .....and staying within his parameters, he's right.
Whatever a person who paid for a car wants to do with it is OK by me, as long as the steering and brakes work properly. Now some things I don't personnally agree with, such as molesting a solid, original survivor car. If the engine is burning oil or making rude noises, for sure repair it. If you find a fairly solid body without drivetrain, run what ya got or can get. Personally poking a 318 to 4" slugs is the hard way these days. Stroker kits are readily available for most any engine at reasonable cost, usually not much more than grinding the stock crank. Heads is similar, by the time you go through old heads and replace the guides, seats and valves you are real close to the cost of new aftermarket heads.
