73' B3 340 Duster pro touring build

Beautiful. You'll be glad you made that expenditure. 408 cu in?

....and that Missle B-pillar move? Amazing. I never knew.

71' 340 block...(I bought off of HemiMark)
4.070 bore, 4" stroke = 416 cu
Decked the block so that it will be a 11:1 motor

I really considered going 422" (4.125" stroke) or 440" (4.250 stroke) but I alread had the diamond pistons.
