knows his stuff. Email him with what you're looking for and he'll make a recommendation of what he can put together for you. He was very helpful getting my set up dialed in. Though he hates that I went fuel injection, he is a hard core carb guy.
His turn key 640HP 400SBC with hydraulic roller cam and street friendly compression ratio is a steal for the price. If I was starting from scratch I would have just ordered that engine with a solid roller and a little more compression.
