What made it need to a 1.125" bore on the mc? Rear Disk upgrade? I love the hydroboost set up. I think they work great on my stuff, though I just used stock stuff on mine.
That bare block is SEXXY!
I'd like to know the particulars of the 4l80e build also. Did the tc just require a new 32 spline input? I know that is what I did to the np246 I put together for our Burb when the pump rub took out the original.
Great build! Keep On Keeping on. My neighbors would be having a coronary if I had our truck on stands for more then an afternoon.
Looks like they dynoed with a carb? Timing stated to be 40*. Is this locked there or are you running a dist with vac advance and mech advance or one? I'm no guru but the bsfc looks low and the engine might could use some tuning to get more out of it. Either way it DEFINATELY makes PAH! Will they be making any pulls with your fuelie setup?

I think this guy wants to acquire your original tank.
