Update…
*Replaced flex fan with 17” 6 blade steel fan. Cooling much better. In town driving, close to 200. Highway 180-190. No overflow issue. Still looking for a 66 Barracuda shroud. Measurements of an aftermarket shroud won’t work.. maybe pre-fab in my future…
Electrical Drain
*found a faulty brake switch. Replaced no more drain..yes!!
Two issues resolved.. and of course, a different one arrives…
After 35min drive, longest with this engine, no issues until I tried to start the car after it had been sitting for about an hour… acted like it was “flooded”, would “idle” and some backfiring through carb. After 10mins of this, started and ran fine back to the house… I’m thinking timing.. since this is not in my wheel house, off to the shop this week so they can tell me what I did wrong….
I appreciate all of the help and I’ll let you know what they find…
