So now I am making a wish list of stuff for the motor.

Anyone got any opinions on:

CAMS

LIFTERS (found these) http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8017468028&fromMakeTrack=true

http://www.ecklers.com/product.asp?pf_id=44478&dept_id=1211

PUSHRODS

ROCKER ARMS & RATIOS

Stealth?
Could use some help here.

Heavy,
Seeing as Katech built the 2005 Speed World Challenge Manufacturer Title's motor and the overall SWC champion's motors, I'd probably give Jason a call over there. I know the Maggie changes things, but they probably know a thing or two about increasing flow...

I can't imagine what a properly built BLOWN-LS6 would feel like....probably make me fall out of love with my NA LS6 V....

Too bad you live on the east coast.
At the meet we had three blown V's.
As to what's "proper", LAWFIVE was letting his car be test driven, and I am sure LUNA would let another V owner drive his if he was asked.
YA GOTTA ASK though (at least with me you do).

I will tell you, it is a totally different car, and you wouldn't want to go back.
Like owning your own Six Flags ride.:highfive:

WHEEEEE!!!!

Do yourself a favor, build the bottom end first, crank, rods,cam chain and gears etc. No additional power from it and you will spend considerable money there, but if you end up over 500 hp or so the stock bottom end may not hold it.

Thanks for the info.

This is a wish list, and I don't want to tear down the motor (yet).

However, I am not beyond doing rocker arms and maybe the timing chain.

Looks like ECKLER's makes or distributes some nice stuff.

There is nothing wrong with the stock rockers. If you're looking for a bit more lift, call Crane for their 1.8's. Very expensive and if you do a cam later, your stuck with them due to P/V clearance issues. Harland Sharp's are o.k., I have dynoed them back to back on a 408 and 346 and so no gain. As a matter of fact, the stockers let the motor rev a few more hundred rpm while holding power instead of it dropping off. To heavy??? There are better ways to spend your money than doing rockers. If you do a chain, you might as well do the cam, it's right there. The stock LS2 chains work very well, big improvement over the LS1/LS6 chain, no breakage issues that I have heard of. The Rollmaster's have had issues.

What are you trying to accomplish with the cam? stealth, top end, low end, driveability, lope??? ??? What other mods are on the car? Where are you located?

I don't think I want more lift, but a rolling rocker sounds neat.

What am I looking for?

This is a wish list, and I am just shopping at the moment.

As for current mods, they are listed in the ownership signature.

I would pull the heads and drop the comp. and throw some boost at the F'r.

With the maggie I already get the boost I need.

I am really researching the rolling rockers though, as they seem like a neat way to go. However, from preliminary info, to install the replacement studs one has to tap threads in the head (?) BLAH!

It also seems that the single row timing chain is a "weak link" (no pun intended) but if I replace with a dual row I may as well do a cam (mild).

Appreciate all input though as this is a wish list.

There are no replacement studs that require thread tapping, and I doubt you will see any gain to warrant the expense or work. Unless of course you up the r.r. ratio. But just going for the "roller design" and expecting a gain, won't happen. If you want, I have a set of Harland Sharpe 1.7's I'll sell you. They have about 2,500 miles. $225 shipped.

Our dyno testing has found that roller rockers are a waste of money.

Could they be more reliable? Perhaps that is the viewpoint that Heavy has.

Ok, rockers are out unless I just want to wrench on it.

Thanks for that info.

I am not looking for HP gains over reliability and it is a wish list.
