    I was at Sebring with Scott McKay this past weekend.. My car ran good except me not changing rear brake pads on time. Scott's car experience a mass air sensor issue either with the connector adapter or mass air itself. He missed both races Sunday because of it

    Other then that the car is so sweet! I qualified 6th for the first race sunday and finished 4th overall! Best time I ran was in qualifying 1:25.043, about 1sec faster then AI.

    I'll be posting video as soon as I can, in Philadelphia for work all week.

    My engine upgrade is finally completed. Car cranks a little hard, I attribute that to a freshly prepared block and all new parts. After 24 dyno pulls and lots of play with timing and fuel pressure was only able to get 263 hp and 268 tq. A little disappointing! Car sounds and runs great but just pulls weak. Any thoughts? Good vacuum, no leaks, no misses. Curves very smooth with no dips.

    As a side note...when first on the dyno with standard settings we ran VERY lean! You must use an adjustable fuel pressure regulator with this engine or you will grenade it in the front straight. My final settings 16 deg timing and 61 lbs fuel! It likes to run on the rich side and heats up quickly when lean.

    quite a difference from John as 65 HP is a huge difference, I belive John has a new lower end also, something is not right, sure there are no error codes ?

    I agree...no error codes. One suggestion was too long bolts on spider leading to cam bearing compression. This could have been easily missed by the builder since he had to order new spider assembly and put it on later. Will be running compression check etc to assess other factors. I really hate to pull the motor out having just put it in!

    Tom,

    Looking at your torque number it seems like you are down a cylinder, maybe double check your rocker adjustment for a valve hanging open? Also could be a bad spark plug or wire, you can try disconnecting one wire at a time to see if there is one that doesn't lower the idle, just be careful pulling them if its running or you'll get a nasty shock.

    Did you check the valve guides before installing the heads as we found that the guides were a little tight and could cause some issues

    You were spot on, Jim. Turns out I had a bad plug wire on #6. When I pulled the plug it was wet and appeared unfired, runs much better now and a recheck of the plug shows same clean burn as the others. Now it's back to the dyne first available day!
