Knoxville's Heads 'n Cam Swap Build Thread

[Knoxville]

Going to be making a little change with the G8. Previously I was running the Vector Motorsport's Stage 2.5 camshaft with the GMPP LS3 CNC heads. For more details on the old setup you can find the build thread here (http://www.g8board.com/forums/showthread.php?t=58950).

The new setup I am working on will be a custom spec'd Lunati camshaft from Rick Crawford. Also the setup will include Rick's ported and milled heads.

Today is the first day that I started working on the build. Put in about 7-8 hours on the car and made some pretty good progress.

What kind of power is this new setup going to make?

What kind of power is this new setup going to make?

I'm not positive about this. I'm thinking that the new setup will yield similar Horsepower and Torque numbers (+/- 15RWHP/ 15RWTQ).

One of the biggest reasons that I'm doing this is because I feel my old cam would be better suited with a bigger stall than what I currently run (Yank SS3200).

My goal is to regain some more low and mid range power and have a more useable powerband. My current setup feels a bit lazy with the high LSA in the cam with a stall that is probably too small.

Worked on the car a little bit more yesterday and made some small progress.

Removed the valve springs and stems from the head:

Removed the crank pulley off the crank, air tools ftw.

Also I was able to get the lifter trays and lifters removed from the engine. The lifters look like they are in great shape. I can see about half of the camshaft ant it also appears to be in great shape with nothing more than normal wear and tear visible.

Damn you just don't quit! What's the specs on the new cam??

[Knoxville]

Lunati custom grind 223/231 .610/617 112+0

[JohnnyT]

Awesome! You'll definitely get good mid-range out of that.

I still need to dyno mine since the FAST install, but might not get to it since I may be getting a snail come winter... :)

What are the specs on your cam?

[JohnnyT]

What are the specs on your cam?

238 / 240 - .600" / .600" - 112 LSA + 2

Not boost-friendly with the 112 so I'll get a new one come winter...
