Mike
Doing a motor for customer and that’s what he wants. 6005 castings are for 390-428 combo and the 6008 is for L/R-M/R 427, they have a machined CC just like a C5AE-6090-F OEM head and I believe a different valve spacing to fit 2.190/1.73 valves?
Mike are you the person running the B/SA Fairlane out of San Jose?
If so, I would like to talk to you.
Two-1-zero-373-4zero zero 4 is my number.
Thanks
RJ
