Slant engine builder in SW PA.
A friend of mine has all his work(slant 6) done at Brocker's speed shop Rt 51 Pittsburgh near Century Three Mall. They have been there for ever.Greg's car the "Ruster" runs 12.teens @ 110 mph at Pittsburgh Raceway Park.
You are correct that most think you can build a slant like any other V8.Nope, Apples and Oranges.Yes the basics may be similar but some things apply differently. Good Luck !
