I'm running 11.9 compression. BTW I heard from a reliable source that the g5 is 236/242 .598/.601 or something like that..mine is on a 114. Your 111 is what gives the power down low, that much I know.

Personally I'd be concerned about guide life and spring life with that much lift on a daily driver. If you have any doubt on your guides, use that for an excuse to do the heads. You don't want to drop valves like the ls7's do.

I heard a rule of thumb on adding a point of compression but I don't exactly recall what it was and I don't want to misquote. Seems like a point of compression was around 10 to 12 rwhp/rwtq, and mores down low, but I don't trust my memory on that. Maybe you can get someone to chime in to support that.

I think you could pick up 10rwhp with 12-15rwhp not being out of the realm of possibility. Joe you are pretty much correct with your power gain guesstimate. It not only is worth power at peak, but across the board.

I believe the added quench with the added compression really helps efficiency in the combustion chamber along with the added compression. The two go hand in hand, like peanut butter and jelly.

My EPS was a 234/242/605/603/112+4

Pretty close but the G6 drives better with the same tuner and same parts.

That's not enough power to justify all that work-

TFS it is

The last 2 parts of your post I don't understand though. I don't think I ever said that his very nice numbers came from just the cam? You have to have great cylinder heads to make great power N/A, that's something you just can't get around.

BTW your car runs very well!!!
How much overlap does the G6X3 have?

Guys, if I am running TFS 225's @ 61cc (milled from 65) and an .040 gasket with the stock GM rockers (pm guides), what length push rod will I need?

Any idea? (Martin?)

Probably a 7.450, but that is about as concrete as jello. Best bet is to measure, do you have an adjustable push rod?

LOL. Martin, YCMU.

What are your thoughts on AFR230V2 or TEA's TFS235s on a LS2? Patrick G has a impressive G8 with over 500RWHP.

483 on an LS2 is crazy awesome torque. The G6X3 likes the TFS heads a lot.

Port-matching the FAST helps a lot too.

How is the drive-ability around town? can it be driven below 1600--1800?
