Gentlemen;
I bought the last one Harry Warner had in 1962 when he was still in Burbank, Ca. The patern(s) had just been sold to Bob who was in Long Beach at the time I think.
Never quite got all the money together to finish the whole project and sold the car & engine in 1983. Was a 278" in a 34 3 window Chevy coupe with a Muncie 4 speed etc.
The only problem they ever had was blowing head gaskets between 1-2 & 5-6 with the stock type gaskets they had back then and that only happened if you 'lugged it down' in street operation.
What you have will work better than you think. So be ready for 'whiplash'.
