Time to build the engine

So after the engine in the van was taken out and found to be junk, I got a second engine from a friend ( who I'm sure had all good intentions ) and it's also junk. I found one in a bone yard for $100 and it's good, and I'm happy. So now it's time to rebuild and up grade. I had thoughts about bigger motors but have come to the conclusion that keeping it simple is the way to get it finished.
My plan is to use a tripple carb manifold w/single barrel rochesters, cast headers, and a mild cam. Also I was thinking about having the head shaved.
So, while it's apart and I still have not ordered the parts,any suggestions ???

GK I think in the long run you will be happier with a v8, I know its a bit of a swap , but it not that bad . I also sent you a pm Bob

here in the states almost nobody knows how to tune l6 engines the right way, but is possible to get 50 more horses and 24 mpg with a stock engine plus intake manifold, headers and 2bbl carb...people I know are getting 120 horses per liter, you have 4.1 liters in a 250....go figure....v8??...no, thanks..

307 flat top pistons fit, will raise compression. you can mill up to .100 of head without clearance problems but .060 is recomended for longevity. shaving head alone will raise 1.1 on compression. 1.94 intake valves will fit. when selecting cam, your duration will determine powerband. pick duration you want and search for highest lift you can get.triple intake is same as stock.
