Got a set of Darts for a BBC that are currently 355cc runners. Is this head too big for a 496 cid 13:1 deal with a 250 hp n2o kit? Application is a jet boat, thanks
It would take more than a band aid. More like a full body cast. Chris, even if you go with a small camshaft, how do you ever get port velocity. Like putting 450 carbs on a Dart tunnel ram.To bandaid the cylinder head size you will need a very small camshaft.
