Engine has been together about year, but having blow-by issues due to glazed cylinder walls from the start. I did give it a couple runs down the track best it ran was 12.4 @ 116mph..thats with smoke coming out the tail due the oil blow-by and I'm sure I'm losing compression do to this aswell.

Haven't dyno'd the car yet, but where would some of you expect it to be?..once it re freshed of course,

Also any predictions on what it should run?

Sounds to me like the machine shop used too coarse of a bore finish which
tends to wipe the moly off the rings and causes smoking....Car should run
easy elevens when right

mine made numbers in sig when it was fresh off the stand. seemed to run a little better after about 2-3 months. made that power threw an M6 and 12 bolt.

Thanks guys..I am really hoping that it would trap above 120 mph once re-ringed.
