i just picked up spf 1837 this last saturday. i'm from the chicago area and had an open trailer so that every time i looked in the rear view mirror i realized there is no real need for viagra. dealing with dean rosen, jim gander and mark dove made the entire process enjoyable and alerts us all that there are still great people out there to do business with and these are some of the very best. i heartily recommend that you can do business with them and have complete faith that you are working with true professionals that love their business and do it with ethics. my engine is a 577 cu. in (429 slightly enlarged) with c460 heads flowing 525 cfm, crower rods, je pistons, 1250 holley, titanium valves, external
oil pump and a stefs
oil pan. the engine makes insane h.p. no need to talk too much about it.
