Hi, been reading TT for awhile now and stealing lots of good info from it. I've been working on doing some deferred maintenance on the boat, so I've been looking at a lot of more random parts. I thought I would post all of my research/parts list in one spot for those that might be in a similar situation. After all, these boats aren't getting any younger. Hopefully this is helpful to someone.
In general, I use a 1992 Corvette 5.7L OHV (P engine code in VIN) to find similar parts for the LT-1. So far, it's worked pretty well.
I also have a MC single axle trailer that I've done the UFP drum to disc brake conversion on. Trailer details are as follows:
And finally, I haven't tackled this yet, but plan to, so here's the info I've collected on changing out the carpet:
If you've got anything to add that I haven't covered, let me know. I know about the CPS thread, but haven't gotten around to adding that info yet. Also, if anyone knows where to get the service manual for the LT-1, please chime in.
