L29 tbi Unicorn?

THOSE are the casting numbers that I want to see, along with the pushrod length (flat-tappet uses longer pushrods than roller-lifter.)

I will try to pull the valvecover off tomorrow and send you a pic. Maybe get a pushrod length too???

I have no direct expereince, but I've read that the late TBI engines were built with the new Gen VI block castings.

You didn't get the fuel injection system, or you removed it already?

I did get the tbi unit. It was removed to keep from getting damaged during engine removal.
