I like all the tunning you do with the car. I am trying to reread to learn from it myself. This year my goal is to learn the limit, and how to improve myself so I know how to improve the car. Thanks for all your insights, and I look forward to seeing your car next weekend.
OK, I lied. I played a little today. I wasn't thrilled with the RPM matching capabilities of the carb. The primary squirter was lean and it was very difficult to make a a good downshift. I found this chart that graphs all the different accelerator pump cams. The carb came with the pink cam and I never changed it. I had played with squirters multiple times over the past couple years. I decided to step up to the blue cam which brings on the fuel much faster than the pink cam. It made sense with the rpm match scenario. It's a quick pop of the throttle on a down shift that likely doesn't see more than half throttle. It was pretty good cold but got a little fat as the engine came up to temp. I decided to drop the squirter from a 40 to a 35 and I can now rpm match pretty damn good.
Nice! Cant wait to see how that beast does this year at RTTC. Not to many BBC cars Im sure. Hey Todd do you have any Vid's of you car at idle with the new motor??

My harness bar came in yesterday from Ridetech. The were nice enough to give me a $250 gift certificate for placing their stickers on my car during the Optima Challenge. After watching the road course video, I realized how often I had to reposition myself. Rodney and I cooked up a plan to make one of their Tiger Cage cross bars work for my application. Rodney sent out the clamps and I measured the center to center and they welded it up and sent it my way. I'm really impressed with the Tiger Cage materials and fitment. Rodney mentioned they may start offering these to the public and set up a jig for my bar.
The plan is to install it for events only with a set of 5 point Simpson harnesses.(I need to order tomorrow) Two bolts and a little love from a plastic hammer is all it takes to install and remove the bar. I switch back and forth between two seat settings on the street and the farthest back postion I like isn't available with the harness bar. I plan to lay the lap belts in the rear floor board and bolt them into the same position as my current 3 point. Some of you are probably wondering why the bar is so high. Your belts should be close to 90 when belted in the car. Opinions vary but they should be mounted between 10 degrees down and slighly above 90. Sure I could've mounted them lower to make them less of an eye sore but I'm always function over form.
