By originality, I meant that not many people have built up 2.9s in Bronco IIs.

I think with a different cam, port matched, ported and polish, and a set of headers, another 20-30 more HP could easily be attainable. Like I said, the European version of this engine made about 20 more HP stock, and thats not the crazy DOHC version, just the regular OHV one.

There are a couple of write ups on the 5.0 to 2.9 throttle body swap on the internet.
