Hey Jim, nice to see you wander thru the race board.

The 505 motor is an RB block. 0.030 over on the bore with a 4.250 stroke in it. I'm strapping it on the dyno today to see just what happens with these different manifolds.

Good news on that 470. I'll most likely sell this 505 when I'm done with the dyno testing. Hopefully it finds as good of a home as that 470 did.

The LM1 is one of the greatest tuning tools ever. One of my next projects is to use the LM1 on my car and see if I can actually dial in a Holley Dominator so that it works on the street. I'm not sure if I can get it to a point where it drives super nice but I figured it would be a fun thing to mess with.
