The blocks appear identical except for the knock sensor plate bosses. Before I spend money on boring the Diamante block, I'll bolt on the accessories and make certain everything fits.

I'd like to incorporate piston oil squirters, but I'm not interested in experimenting with them when I don't know the oil pump flow rating - or what will happen to gallery flow/pressure if I tap the main gallery to supply the squirters. Note that most of the squirters in the article have a pressure spring to stop oil flow at idle/lower oil pressure to insure sufficient oiling at reduced rpms. An engine might be quickly ruined if the springs weakened or stuck. Any squirters that I might fabricate wouldn't incorporate the pressure trip springs, so there would be a danger of insufficient lubricating oil flow at lower rpms.

I'll add an engine oil cooler - not the same as piston squirters, but better than not having one.
