Very cool, i had a mid 11 second isky solid W2 69 340 dart 4 speed back in the late 70's early 80's, They are fun cars

That cam is very similar to the 231/239 @.050 Ultradyne Hydraulic Flat Tappet cam that makes for a really strong 340/383 replacement cam with bolt ons, It really picks up the power without killing anything off the bottom.

I suspsect with 1.6 rockers you'd make a bit more power if you have the spring clearance.
