308??? First I've heard of this. Is this super unshrouded valves? Just curious as to what the deal is. Not being a dick, just wondering.

Well .030" over is a 306, so i'd just assume he had to go .040" over. No big difference.

Exactly .... just like .060 over is a 311.

Well guys, gimme some more credit then that! I understand the math involved, and what you need to do to get to a 306, 308, etc etc. I'm just wondering if there is markedly improved performance by doing a little more machine work. I see 306s all the time.

The reason for 306s, and correct me if I'm wrong, is to unshroud valves.... its certainly not for added displacement! So what I'm wondering, is a 308 better then a 306, if so why, or did the builder just go what the hell, might as well kick it up a notch?

haha i get what u're saying. Depending on the block used, .040 might have been needed to get it straight. I guess we'll have to wait for his response. How big of gain is made by unshrouding the valves?
