boy, the extra speed can be real good.
now i have a "be careful" story; a model a friend of mine, had just bought a pickup 29, standard A engine, so he decided to put a Snyder's head on. went on a tour w/ the club, and he was passing everyone, uphill 60, dynamite man, wearing a big bug eating grin, wellll, he blew a piston thru the wall, now he has a "B" engine with a Snyder head, boy is he a happier camper now.
