The "Throw Away 318"

You are essentially using just the block and using 340 360 everything else which has been my point all along. 318 guys will say "318is just as good as a 340..." which is misleading. They never finish the sentence which would go something like "...with ,mods, and a wise choice of parts from a 340-360..."
Why not use used parts from a 360 on a 318. That's the way it's always been. use what you can get your hands on for cheap.
My first upgrade on a 383 years ago was to put the larger AVS off a 440 on it.
it was not enough for my dads 440 , so it was free after he upgraded to an 850 DP Holley.
