Sure wish I could be there with you at the SGC Gathering,Lamar. My health has been really bad the last couple of years,though,and it doesn't allow me to get away all that much. Please give everyone my best regards.
Thanks for remembering my birthday. Will be 52 on the 23rd and I feel every year. :yes:

I've owned two modified ZR-1's. One had a Vette Doctor LT5 with Van Deventer siamese plenum,Jeal intake cams,and Jeal headers.
My Callaway ZR-1 had a Doug Rippie LT5.
Aaron is the most meticulous LT5 engine builder I've ever known,,and I know a bunch of them.
If I can help you with anything ZR-1,just drop me a line at [email protected]

I remember you talking about your health. You may not remember me but, I was sitting next to Josh "SurfnSun" at your table when the B-day cake came out during the SGC gathering. BTW the motorcycle stories were amazing :eek: :hail: lol

I'll give everyone my regards and I'm sure everyone is glad to see you're still around and playing with some :cool: toys. Also I saw your Callaway Aerobody car at a local show this summer and it is still looking good.

Its a standard deal pressure oil in with a -12 drain line to pan there high enough to drain.

Tom, I've got a 91 LT5 motor just waiting for your teaking for my first "real" project. It already sports LPE heads, intake and the larger throttle body. I'll be following your progress on the 91 Z you are working on now. :hail: I',m not dropping into a vette so space won't be a problem.

I picked up a 6 stage weiss dry sump with the same specs as the ZR1 oil pump and am concidering running that too. Did you guys ever consider a dry sump system for the 91 or is space a limiting factor? it doesn't look that difficult to integrate once teh oil pump internals are removed so teh feed line to teh stock pick up location in the block still gets oil to that beautiful crank first.
