Yes, small bore. Going to trade it in for a large that’s been set up to run. As of right now this is just a core. I talked to Rudy at R&P Blowers. He is The one I bought the last blower drive set up from. He’s in Waterloo Iowa. Maybe if I go up and see him soon I can stop in and say hey to Cootz! Thinking about putting her on a stroke or 348, I’ve been looking at a 64 impala two door hardtop. Just something else to suck all the money up! LOL Small bore blowers are real popular for street rods and small cubic inch motor’s to drive on the street.
