I took off a 13 inch flex plate for the PG today. Neat little Powerglide, no cooler lines just 4 large holes in the bellhousing. I have never seen that before. Was there a 13 inch flywheel by chevy and what would they be on? I would like to use the original engine mounted starter. Also, do you guys know of any performance parts, intake and headers? I have only found headers through clifford perf. Thanks Todd.
