Nathan,
Really sounds like you have a handle on this thing, I don't know if you are the first guy to do the electronic injection on a two port head especially with your design to get all of the fuel into each cylinder specifically when the intake valve event is happening but in I know some 3 port GMC guys that are sure interested in what you are doing. Can't wait to  see what it does with the hair dryer on it.

There is a Chevy 6 guy interested in this stuff as well!

Well gang, we're going for it.  The motor's already out and apart and the 5 main crank is being fitted.  I didn't realize that our 3 main crank had actually had the flanged welded up but apparently that mod is only good up to 160hp if that means anything.  We'll drop in the last known good cal that I tuned on the ERC gas and make a couple easy passes before going for it. 

Here's to thrashing.  :cheers:

Update

We're up and running!  :-D

Got everything swapped over from the roadster and into the lakester... that is of course after the new crankshaft was dropped in.  Got everything wired up; EMS, 4 channel O2, 4 channel EGT, datalogger, GPS, AIM dash etc etc.  Dropped in the last known good cal, double checked the timing sync and it fired up on the first crank. 

Starting out with a couple part throttle passes and then shooting for 140 and if all goes well maybe 150.  Wish us luck and see ya on the salt.

Well, we did it.   :-D

The short story: we bumped the record to 150.2xx mph.  :-o

I'll get to the long story later but we faced some technical difficulties - none of which came from the electronics!  Something about using a severely cracked 70 year old cast iron Winfield head and blown out head gaskets.  :roll:

Thanks Scott... nice seeing you as well.  When they called out a 150 speed over the radio I just about did a back flip!  To say I was elated is an under statement.  I'm still smiling and shaking my head in disbelief that we actually did it.
