I picked up a complete 2.0+ engine today, came with all sheetmetal, alt, starter, fan, twin Italian 40 IDF carbs, etc. The seller got it second hand from a disabled N. Texas guy who'd crashed his 'real nice orange 914 with spoilers'...he remembered that it was built in Ft. Worth TX and said that it was over-bored but could not remember the details - said "it was built to a 2 point something" (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/headbang.gif) . Said the PO seemed honest and assured him that it was a fast, strong engine. It has a GA engine number. He was asking $700 for everything and I figured at the very least it was a descent price for a 2.0L + dual 40IDF webbers, so I bought it. I've asked some locals if they knew anything about it and none did.

Whats the general concensus, just do a leak down test, compression test and use it if within spec... or break it down and start taking measurement?

It didn't dawn on me, but you could have a low compression and a hi-compression 2056... Lot's of people do 2056 when rebuilding a 2.0, is it usually with dished pistons or flat tops? Why would you want low compression - besides turboing? Is there a problem with valves hitting piston tops or something? Is it that some people want to use low octane fuel? Is there an advantage to it? ... also would the extra volume that the dish creates increase the displacement, technically?
