Eddy heads. Can I/Should i...?

The wierd thing about the low comp 318 race car, was that the "thrown together" motor wasn't that much slower than the guys 360 race motor had been...I didn't know the guy, just yakked with him at a race, but it was interesting how fast that 318 was. I don't know how scienced out his previous combination was...I remeber it had a lot of gear and a loose converter for the previous engine which probably helped a lot. Sort of how deeper gears are used to help out a low horsepower engine, like a lower classed stock eliminator motor. 5.13-5.38 gears behind a low horse 318-340 are pretty common in Stock class, or at least used to be.
It amazes me how some guys put a combination together that sounds like it really ought to work, but doesn't...there was a guy at my track that had a 70 Duster, 12.5-1 compression 340, W2's, 4500 stall 9" converter, 4.56 gear, slicks etc. It looked like a well set up car, sounded good....and was running about 12.0 et's.....10 seconds worth of parts in a 12 second car! makes you wonder how it went so wrong!
Sorry for rambling, use your money wisely as you see fit!
