Just taking an extended break from the madness again so been surfing here! I didn't realize the racing season started so late there. I am dying to hear how you make out. I think you will be impressed how far you can push that little LM7!
April was cold and had a lot of rain, so GLD ever opened it's opening tomorrow but there is rain in the forecast. Usually the track is sh%% first week and crowded pointless do anything..
I’ve had 0 issues with LS9 gaskets on the alum 5.3.
However, I’m switching to the BTR “small bore” version with my new LC9 block.
You should check them out.
Currently my '67 is running a LM7 SBE, stock L99 heads, a Capizzi cam grind, ARP hardware and a Melling oil pump. My long term plan has been to build a forged LC9 and to run aftermarket heads.
I've been working with the following industry players for an all-forged boost engine that is getting built this year:

I plan to reuse my Holley 302-2 oil pan and Holley High Ram intake.
The block is over with Graham Jones @ FastTimes. He determined that we are good with a .005 over bore which was going to effect the piston selection.
I kicked back and forth staying stock crank but the one in the builder block was not usable so that was not even an option.
Again this is a parts list in progress, I'll note when it's been edited.
Good choice on the 10295 pump. Always have great luck with those and the right bearing clearances for the application.
Interesting choice on the Delphi LS7 lifters. I do like the GM LS7 lifters for moderate, to budget builds. What are the spring pressures you are having Graham target?
Tim (Helicoil), LS7 lifters are more budget friendly but I know a lot of really knowledgeable folks including yourself would favor something like a Johnson 2110. I need to do a little more thinking about it.
I have had good luck with the GM Ls7 lifters and the right spring pressures, I was just noting the Delphi versions, may not be the good ole' GM lifters. Be cautious.
