Well I think that GMPP has a decent handle on what the end users are looking for. I guess a little understanding that the process moves a little slow sometimes.
It's very frustrating when you have the parts in your sights, but the procedures in place need to be followed. blocks, intakes, heads are all coming for the LS series engines. It's amazing what some guys go through to get the latest new parts. (can't say that I blame them Hehe).

I am also frustrated that because of completive reasons that I can't share everything here. Believe me I am pushing my contacts very hard to get as much info out as possible.

As far as the NMCA and a proposed LSX type class I can't answer any of those questions. I have not been part of those discussions. What I do know, is that GMPP wants a series that lets LS racers show off their stuff.

I don't know what policy violated but in a previous post discussing a series my posts were deleted.

So I will probably post that information elsewhere out of courtesy to this site.

Sorry about the delay, I've been on the dyno all day an am behind at work

A wealth of knowlegde and someone is deleteing your posts Thats sad

 

Robin, I can see one post of yours was deleted by Nine Ball, not sure why but perhaps it was advertising related.

I'd like to see an LSx class happen in the NMCA, LS1TECH would gladly throw a lot of support behind it. I'd do an NA class and a power adder class. Most of our guys are not going to do 25.5 or 25.2 so keeping stuff above 8.50 is the way to go. Very few of our guys could be competitive in Xtreme Street. PM me if you would like to chat at some point.

Perhaps I missed it, or it is just mot mentioned in here, but is this block going to come with provision for conventional sbc motor mounts as well as the LS style mounts? Just wondered because that would more easily open up more avenues for it. I believe the Warhawk block mentioned it was going to come with provisions for both. Also, what about the one missing bell husing bolt hole (for the old school tranny)? If I remember correctly it was left out because there was not room for it before penetrating the water jacket or something like that. Would this block offer a pad there or something there to possibly use a shorter bolt or better yet maybe a stud? I was thinking this would make a nice refresh option for a marine product as well. Now if we could just get someone to make a decent iron head as well (or find a way to anodize the inside of the water jackets in the aluminum ones).

 

We race, so we try to find any advantage we can.....simple as that. Just a fact of racing these days.

There are options coming yet this fall.

Thats it real nice sweet Coming March 2007

 

4.259" bore with .200 min. wall on 4.400 bore centers ??? That would only leave .141" between the cylinders. Offset 4.459" bore centers or non 90 degree bore locations ??

 

The flyer I got says 4.250 max bore, which would only work N/A.

I saw the plastic model, and all I can say is WOW, very cool. Cant' wait to see a real one.

 

4.25 LSX block +4 in. stroke+ LS7 heads ported+260@.050 cam=
a big dose of

 

sounds nice but torque is where its at!

 

uhh... if you're not making torque with a motor this size, you dont deserve a motor this size.

no. i'll rephrase.
i think you'll have to try REALLY REALLY hard, for the motor to NOT make torque.

 

Does Anyone Know The Part Number To The New Lsx Block?

 

Your part # for the GM Performance Parts LSX block is 19166454. This LSX block includes the following: Cam thrust plate, Rear Cover &Tappet guide.

Hope this helps

Any dates are just speculation and rumors at this point.
