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

What I meant by that is all of your constricting rules. You know, the gotta buy it and not already have it. If somebody already HAS a good 340 core and all it needs is a basic rering and rebearing, by your little box, they're disqualified.

I GET the point of your post and agree. But it's slanted to your favor right away. Because we all know an already existing good core 340 with 3K thrown at it would eat all 310 commers for lunch.
But when newbies come to this site with their 318 car and limited budget, and some tell them to "get a 340"... they have to buy one....

And your premise is really flawed because why would ANYONE use the 340 when the '69 440 6 pack is right behind the 340 in the same guy's garage.. !! :poke:
