IMO the winner should be invited for years to come until beaten or in your case retire LOL.
The rebirthing of Penny is coming along sweet Steve, what made you decide on changing out the shocks for the Penske's.
Maybe I missed your explanation in the rebuild thread or is it a status, got to have them situation

Yea, it's fun to go back.. to be honest if we wouldn't have lost a PS pump we would have came in third overall.. if the rules were like they will be this year (where you get points for placing instead of an added time) we would have finished second behind the Cobra.. So Penny isn't quite past her prime yet.

Many of the events like Motorstate and such ARE qaulifier events.. So you wish has come true.

The switch to Penske is because they are willing to work with us to make a shock to fit the car. None of the "off the shelf" Bilstien sizes are working in our wierd application. The delay is that F1 called our guy to Europe and since they spend a bit more $$$.. lol

Penny's last engine... well, at least final for a LONG time..





We start the machine work early next week.. everything is here, sorted and ready to go in. Only thing I'm waiting for is the custom Canton pan to be finished.

Install on August 26th at the latest.. then ready for the Holley LS-Fest and RTTH events.

RHS short deck block - 4.155 bore
Mast Motorsports 12-degree LS7 bad ass heads
Lunati Pro Crank - 4.250 stroke
Lunati Pro I-beam rods - 6.125"
Weisco pistons (11.3:1) designed for the stroke
ARP everything
FAST 102mm LS3 style intake
Mike Norris ported TB and transition ring
CHE bushed LS7 rockers
COMP vertical bar lifters, pushrods, timing chain, etc
Moroso oil pump

We have two camshafts to try.. one is really snotty.. both are hyd.

The smaller is a just a touch bigger than the one in my 454.. the other is.. well.. bigger

Thought it would be fun to see the power differences.

Displacement is 461 cubes.. With the big cam we should be over 700.. no idea on torque but more than I need.

I will say the finish work on this RHS block is pretty damn impressive

That RHS block is pure sex! I've seen it on a few builds over on LS1tech and they seem to be the hot ticket if you're going all out.

Nice job Steve; sounds like your NA motor will be top of the heap unless someone buys Tyler's 'friend's' C5....

Yeah, but by the time someone gets that C5R engine running Steve will have something more badass than a C6R engine in his car. I don't believe for a second this will be Penny's last engine. There will always be something better, and someone will always want to give whatever that may be to Steve

Yea, for an NA motor it should be able to least have a fighting chance against all these blowers.. but the lack of weight will pay off huge in tight handling like autocross and such.

The C5R deal is sick.. although running race gas would make me sad.

I will tell you.. swapping out engine on a "done" car is a real PITA.. I really don't need to swap from the current 454 but I was asked by RHS/COMP to build something and they've always been great to me.

Really don't know what I would build to go beyond this. I could dry sump it but my Canton pan has never let down so why? To go bigger I would have to move to a tall deck block and that would mean custom headers and intake.. no thanks to either of those.

I need to spend time dialing in shocks and such.. but I learn more everytime I do this engine exercise

[Steve1968LS2]

Small update..

8300RM Penske shocks are done and will ship to Global West on Monday. Supposed to have some new uber valve in it.

Yesterday I drove her to Best Of Show where we dropped the Magnum and replaced it with the one from Track Rat. Solve the first gear problem so the syncro was def bad as I suspected. The one from the car will be shipped back to Tremec and fixed for Track Rat.

Have done this so much that it's now a three hour job. Thanks Chris!

New, longer rear wheel studs are installed.

BottomFeeder front spoiler deal was modified and installed.. nice little item.

Sometime this week will swap out the cam for a three bolt version and install the Penske shocks. We will test the car on the 30th with the Pozzis and Penske is flying out an engineer to help set her up and to help set up the 2010 SS which is getting a prototype set of Penske replacement struts.

Car runs good now but I need to deepen the oil pan near the front crank lobe since it's too close and frothing the oil a bit. Engine runs, in hot weather, at 180.. even in high traffic it wont go over 190. Oil temps are actually too low and in the 180 range. If I try hard they will go 200 so I will make a block off for the Setrab for street use.

Two new 275/35/18 viper spec PS2s are on the way.. anyone want to buy my slightly used old tires?

Don't make a block off -- just put in a thermostat.... You'll forget the block off on a track day - and that won't turn out good.
