But then again that 318 of yours you're probably only up to about 60 miles an hour LOL...

I think 94.9 mph is it's best LOL... and that's better than any factory '73 340 with 3.21's. That is what this low dollar 318 was built to do, run with a factory '73 340 Duster on a less than 500 dollar budget (spent 498 :D)
