L98 rebuild
Hey all, I put this up in the TPI boards but am also putting it here too.
I picked up 88-WS6's GTA. Only major thing wrong as far as I can tell with it is the rod knock. I managed to get a look at the bottom end and was able to get ahold of a few of the rods. Number one is knocking, don't know if there are more. But I just want to do a factory rebuild assuming I don't find any severe problems in the bore. I AM NOT building a monster here, that is what my 84 TA is for as the 84 is in some ways more built up than the GTA. If I have to have it bored 30 over to correct something then so be it, but I am going for a stock 350 rebuild here.
As far as I know most of the stuff you can reuse. The top end seems solid. I know most of the time people rebuild the bottom end and then the top end blows up. But what the hell, the motor only has 87K on it. I may get away with it. For now this is what my possible shopping list is, I'm running on the assumption that the crank and rods are screwed. However, the crank might just need to be turned and get the proper bearing size, and the rods might need to be trued and proper bearings bought.

Naturally, if I find bad injectors or whatever else that might be gone I will replace that as well. Do I have just about everything right there? Or is something missing?
