Hello it's me again. So after the valve incident about a couple of weeks back I decided to swap the 1980 block,with a 79 400 sbc 4 bolt or at least I think it's a 4 bolt. This block from a 1979 gmc centurion motor home. I swapped the throttle body stuff over to the 400 sbc. Including the TBI heads and intake and cam. I know,I know TBI heads are junk. But.....on the other hand they're great for low end torque and they run damn good on the 400. It will get a little better compression.
I was driving it around for about 2 weeks. Only started when we hit the cold here.I know it isn't leaking any coolant and if it is I'm thinking bad intake seal or something. But some how the throttle body is getting moisture in it. if it's not coolant. maybe the regulator is leaking I'm not sure.
It's not enough apparently to effect the truck the 400 is strong and the cam isnt bald so I reused it.
