Scotty, no I don't, but I'll check the pcv with the oil cap, thanks! Turbocharged400sbc, I had the sc off last weekend and the sound is away from the TB, but that was checked. It does have two spacers between the LIM and SC though, is that normal or could that cause an issue? Still not 100% familiar with these cars. Wowitsfast, thanks man, the previous owner definitely was meticulous and I plan on carrying it on, thanks for the input.
