i think the 14psi max on stock crank and rods myth has been busted, wally is putting more than that into his.
the stock crank is very strong, balanced its good for 500bhp+ so mated with some good h beam rods it should be ok.
its the heads we are having trouble sorting, pauter make there super pro heads for a type 4, a stock head casting will do 500bhp with a lot of work.
