Building a new 505 With Callies / Mopar Performance Block

Took Andy's advice and dropped off both sets of heads @ machine shop on Saturday morning first thing. They milled all the rocker arm stands so that I can run the stock .047 shims. Machine shop did me a favor and I was able to pick them up late Saturday afternoon. So, the Trickflow 240's and 270's are now done. Hopefully the torx bolts will come in this week for my camshaft gear. Picture of the motor in the plastic bag is the street motor 505 with a solid flat tappet camshaft from Hughes and Trickflow 240 heads. This is one of my friends' motors 10.5-1 that we are waiting on parts to complete. I put the heads on this motor and test fit the hand ported M1 intake. Now back to my motor to start checking valve to piston clearance.
