Yes I bought my duster 6 years ago and 5 1/2 years ago I paid in the neighborhood of 6,000 I can't say it was less or more and I'm saying that's everything including the 8 quart oil pan to the dual quad tunnel ram...
The point was to have something powerful and nice for years to come instead of fiddling with old junk..
For once in my life I just wanted a nice quality motor that I could build and play with and try different cams and try different heads and have great performance no matter how hard I tried to screw it up LOL...
