Re: TCM Merlin 509 Issues
Thanks for the tech support guys. There seems to be more knowledge on this board than at any of these so called high end engine builders.
I did read about the condensation issue with the L-19 bolts. The one good thing I can report is that although I live in a very high humidity area, my motor has never shown any signs of condensation in the vale covers or the oil and I do change it regally (even though it's not cheap - Mobil 1 costs me like US$12.00 a qt. where I live, and I have a 10Qt Crankcase).
As far as the heads are concerned I agree that the 345's are large and I would like the CNC ported figures on the exhaust especially. I think the ultimate setup for a blown 509 is probably the 315 CNC w/ the tulip valve option which puts the Intake/Exhaust flow ratio at like 84%. My heads haven't been shipped and I am going to give Ohio Performance a call shortly to see if I can change them. I know they don't have the 315's in stock though but they should be able to get them.
Thanks again for all your input.
