I pulled my car out of storeage and now I remember why I want to stay with the 305, it runs perfect, after 120,000! It fires up with no problem and runs like it's got 20,000 on her! The LO3 is a great engine, which is why I have decided to mod it vs. getting a 350. My question is for people with modded 305's. Does your car run good, without any flaws. I want to keep that stock reliability, which is something you loose when you mod an engine to much. The LO3 runs so great, and I want to keep it that way. Let me know what kind of quirks you have with a modded LO3!
Thanks, Matt

 

Mine is full of miles as well, and it runs great. check my sig for mods-they're all external to the engine. The only problem I have is either the water pump is toast, or my radiator is clogged.

 

wheres the sig?

 

Arrrgggg!!! My sig only seems to show up when I right a new post. Don't ask me why. Anyways, I have headers, y pipe, high flow cat, 80 series flowmaster, modified stock air cleaner, MSD 6a and dual connector coil, k&n, and shift kit in a '90 305 RS.
