TB should be in today so I'll be able to drop the intake on tomorrow night. I'm putting the tbss intake on with the stock tbss rails/injectors and I need Multec II to whatever-the-TBSS-injectors-are adapters. Anyone know of such adapters? Pics to follow, thanks!

Thanks Jason! I called Ron directly and he sold me the unit with the master install kit for $530ish shipped. You may even be able to get a military discount. Hit Ron up directly for the best deal and he's super nice to deal with. I'll tell you what though, these 4.56's are REDICULOUSLY fun.

We pulled the El Es Juan out last night and found the problem.
I was WAY lean and apparently the stock injectors didn't help. More coming soon.

lol Yep. That's why I have the LQ4 waiting to go in. I'll snap a pic of the head damage later tonight. Hopefully it's not really hurt. It has an indention in the combustion chamber and the valves look ok but I want a machine shop to look at them to make sure I'm not setting myself up for failure. The old 221/226 cam is being sold tomorrow to a good friend who will make use of it. The money I get from that should pay the machine shop whatever he charges.

Slight change of plans; the heads are fine and my buddy is buying them today. I have a set of stock 317's that I'm thinking about milling. Anyone else making good power on milled but un-ported 317's?
EDIT- I just got off the phone with the my machine shop and he said the difference of the combustion chambers could be evened out by milling the 317's 0.25". IE- a set of 317's milled 0.25" will yield the same CR as a set of stock 243's. I've read that 317's outflow 243's stock-for-stock. Is that true?

243s out flow 317s stock for stock
in the sticky section there is a flow chart of all gm heads
Also your machine shop is wrong! You cant mill a 317 .025 and go from a 71cc down to 64cc like 243 head has
roughly takes .007 milling to remove 1cc
