All of us 2006 and 2007 owners have had to endure ridicule from 04/05 LS6 owners for our "truck engines". Just today I was looking for info on NASCAR engines. Guess what I found:The result is a collaboration with Carl Wegner of Wegner Automotive that produced NASCAR's new spec motor. Capable of producing 520 lb-ft of torque and 625 hp with a redline somewhere around 8,200 rpm, this engine is two years in the making and an interesting mixture of off-the-shelf OE components and race-specific parts. In developing the engine, Wegner used General Motors' LS2 engine as a foundation, using the block and heads and even keeping the major dimensions such as main and rod journal sizes, valve sizes, cam tunnel location and size, and even bore and stroke. This allows the block to be pulled directly off the assembly line, making it significantly cheaper than a properly prepared Bow Tie block.
This is from: http://www.circletrack.com/techarticles/ctrp_0704_nascar_new_motor/index.html

So lets have a little respect from now on!

Sooo, they took the truck motor, did $30,000 worth of work to it so it can power some rednecks around a track for 500 miles? Bravo :thumbsup:

The current RO7 Chevy NASCAR motor is a purpose built race motor that has little in common with previous Chevy SB efforts and is not offered in any production vehicle. It more closely resembles a Ford than previous bowtie motors. They'll turn over 9000 RPM all day and produce approximately twice the horsepower of the sucky little motor in a V.

You guys with the little ones...engines, that is are just jealous. I call it "engine envy".
I wish I could grow a "mullet", my problem is I have no hair on top...it becomes a "skullet!" and I would look like the mass murderer in British Columbia. So it is short hair for me.
And nobody get all serious here!

Just giving you some shit dude,alls good.The article I read about the new Nascar engine was it was built from the ground up,which has never happened before.I think for it to be a race legal motor they have to sell it at their parts dept,which is why you can buy the parts.Those motors will never see a production car,unlike your motor that is used in mostly trucks and a few select cars.You can pull a bass boat and I can't,all good.

The RO7 motor came about as the result of the purpose built race motors that were allowed to Dodge and Toyota. Dodge resumed racing after a long hiatus with a motor that was a hodgepodge of parts borowed from Ford and Chevy until they could get their own engine program going. Toyota built a plant in California to build race motors that are also not available in any production vehicle. GM asked, if they can why can't we, so they were granted permission to build a unique race motor. Unless your business says Hendrick Motor Sports, RCR, or DEI on the door, it's highly unlikely that you've seen one up close. The parts are not available to the public. Some NASCAR owners are still using the older SB2 motors.

Better (Flatter) Torque curve stock... Now that's what I like.

peak numbers are all about bragging rights, Flat torque is :cluod9:

Too much fun.

Hey Tony, I think you will be disappointed with 04/05 V owners. They won't be wanting to buy the 09V what with a stroked "truck motor" plus a blower that was originally on old GM 2 stroke diesel TRUCKS! Don't anyone get technical about blower designs either.
They seem to want to stay with their obsolete motor. Oh wait! You are one of them.

TRD high point picked the heads and intakes to give to the teams

Special olympics?

Time to climb off the horse, it's ONLY a motor. A bad ass one but come on, "preserving" it?? I'm glad I didn't get the LS6, some of you may get pissed when I mod it. LS6 = Luke warm (stock).... Now the LS7 :cloud9:

No replacement for displacement. The Engine to :worship: is the C5R stroked and sleeved for 427 Cubic inches of pure fun!!!

Bottom line is I love the LS motor and guess what we are part of the same family.

Climbing off my soap box and just want to be freinds. Oh yeah, we are all driving Cadillacs! Love the car!!!

First year V series, exclusive motor, etc. It may never be a classic, but it'll surely be interesting in future years. Keep on truckin', Bobby!

I've been trying to stay out of this, but...... How come people are putting stock TRUCK intake and heads on (L76/L96)? (BTW, noone needs to explain it, I already know. I was just throwing that out there.) :hide:

03-31-08, 04:13 PM
Realize your just playing but the L76 is a holden intake, not a truck intake :D

I do want the Truck motor heads though :thumbsup:

Why do the LS2 motors put down better numbers when treated to a cam and exhaust? I have had both now.

Finally, now that the writers strike is over, I no longer have cheap assistance to help make my posts funny, hence the fall off in humorous content. I angling for 'pathetic' now.
