bad water pump?
I think I might have a bad water pump on my big block. The transmision is slipping so I adjusted the pinion angle to -3.1234 deg.
I then talked to a local race motor builder and he said that big blocks will spin the rod bearings if you don't have a nuetral safety switch hooked up...so I took the jets out of the carburator and it ran great for awhile...but now the left rear tire keeps going flat....I think maybe the water pump is bad or the fuel pump... Any ideas?

Rollers or flat tappet, solids or hydraulics? A bad Kanooter valve, will cause it to detonate! Check your rear seal. Don*t know about the pinon angle though, Are you running oil restrictors, Also if the spring gets lodged in the oil screen, it could cause a springy pickup.

re; bad water pump
THATS RIGHT!!! we had a bad kanooter once that caused us to have to use a rather unorthodox fuel... Coleman fluid, we set our total timing to 13*. We burned up the upper drive flange, dumba$$ us we forgot to chamfer on the block side! Tee Hee we*ll never do that again!!!
