Which Throttle body?
Tax returns comming soon. Which throttle body should i consider? The 52 or 58? And plan on siamezed runners extrude honed. I have a 350 HO 330 crate engine which has the 212 222 cam. Some day, i plan on stroking her.

to be honest, from someone who buoght a throttle body. save your money and get some aftermarket runner. just port the upper manifold, and you'll get the same HP. BUT if you do get a throttle body get the 52mm. it flows more than enough.
Yeah, I was going to get a new TB too. but desided aginst it and put the money where I needed it.
