pics of some custom work on my LT1
pics of some custom work on my LT1 Took a ride down to the shop today and they were busy on the lathe fabbing me up some spacers for my crank trigger/vacuum pump so I was able to take a look at the motor and check out some of the finish work they've been doing on it. Kinda just wrapping up loose ends. We're still having the issue with the head gasket clearance with the pushrods but the new head gaskets will be in by weeks end so the heads will be quickly removed and put back on with new clearanced gaskets in place.... well enuff of that...
My engine needed a timing tab to verify with a timing light was the FAST XFI is telling us our timing offset was, so as the original LT1 has hard programmed timing with the opti no timing tab is needed. Well not with this motor. So CSM fabbed up this trick little piece of aluminum and mounted the timing tab to the motor. I was real happy with the results.... The other picture is the Victor manifold. It had a water crossover on it but my engine guy wanted to cut it off, smooth it down and then weld it so it'll look like it was never there. We also fabbed a bracket today for the fuel pressure regulator but it wasn't done before i took the pictures.... keep in mind the manifold is in step 1 of the machining process and i'll take some more pics once it gets welded and smoothed over...

You might be able to make a little money with that timing pointer design. That's some nice fab work
Thanks for the compliments guys. I'll be sure to let Lance know. Maybe he'll make more if people need them for their one off builds...

I have pics some where. I figured it out when I was doing the work to put the opti setup on a SBC Gen I
hmmmmm yeah i was looking at an SBC just now and you're right it's different on the top.... Something that lance said was why he had to fab up that plate but i can't remember. It might have been just where he wanted it or the fact that it had to be visible with the WP in place but i'm not 100% sure.... i'll ask again tommorrow...
That black thing that is no longer there is where all opti's are born and live their lives when not on engines..... In the bowels of hell.....
where this one shall remain.... crank trigger wheel and pickup goes on tommorrow...

so what kind of ignition are you going with?
yeah when i mentioned to CSM my intention of running an MSD billet opti on my solid roller 383 with 400 shot about a year ago my engine guy gave me that look right before he burst into laughter.....
my days of opti problems are gone...although i have to say my opti on both my stock plus bolt ons/nitrous LT1 and my 355 low 10 second nitroused LT1 gave me no problems in a few years of messing with it..... I just don't want to start now...
