OK just wondering. You said the merc has always been your dream car since you were really young.. I was wondering what started that? What mercs did you see that made that car your dream car? Was it just the looks of it? Was it the whole car outside, the flathead etc....? How did you always think you would have your car when you finally got one? Did you dream of having the perfect merc the way you wanted it with a flathead? Or with a different engine? You finally did get the car you always wanted but why cheap out now and swap out the flathead? Flatheads are exspensive no doubt... But if you always envisioned your dream merc with a flathead then keep it.. If you dreamed of it with a sbc then swap it out like everybody else does and take the cheap and easy way out...I dont care how traditional people say a sbc is or it can look... Why do what everybody else does... sbc have been used all the time... Why? Cause they cost a fraction of what other engines cost to build...Also everybody and there brother builds them... So you got your dream car! Why cheap out now?
