This is going to be good. Like said by Hi V, not to often if ever you see a Twin V.
Motor looks killer. Nice job man.

Finally started the car last night!!!! At first it didn't want to kick over and found that the injectors were gummed up from sitting. Good thing I just got my new 80lb. injectors on Thursday. Popped them in, made a few changes to the tune, and it fired right off. After running about 5 minutes, one of the injector o-rings started leaking, so I'll have to fix that before it runs again. No biggie.

Here are the latest pics......

I'll take some more pics before I get it all buttoned up.

For the rear I already built a diff girdle that should help. I don't drag the car, maybe an occasional roll race or a run on the freeway, but no 5K clutch dumps. Here's the girdle....

The car is pretty much finished and I've been driving it for about 1500 miles. Changed out the break in oil after a few hours of run time, then changed the conventional 10W40 out around 1000 miles to synthetic 5W40. No worries from what came out with the drains, very little metal particles on the magnetic drain plug. The tune is fairly conservative running pretty rich (10.8 to 1 AFR) at WOT and 14.7 to 1 AFR under cruise and light throttle. Conservative spark map with no knock retard at all. There is a some power left on the table with a more agressive tune. I'll work on that once winter passes.

Here is the last update to the build slideshow.....

I had to pull the exhaust off last week to do some work to it and couldn't resist starting it up.....

This one is a quick test run when my neighbor talked me into taking him for a drive....

That drive was on a rough narrow back road, so I didn't get too crazy.
Enjoy!
