I have two of the 292 engines, the "hot" one has 3 Weber sidedraft carburetors with K & N Filters, roller cam and rocker arms, ported and polished head with big valves, etc. It is really strong, the guy that had this setup on a 292 before me had almost 400 H.P. in fully streetable trim. It is not cheap, but it is rewarding to have a six that will outperform most every V-thing you will run across on the street, beside that they sound great.
