Default Any 441 cu. motor built yet?

I was just wandering if anyone has used a 4.125" stroke on a LS7 block. If so what were your results?
Thanks DG

Yes,

Just a bigger engine which I think is better. a little more tq everywhere and the potential for even a little more power.

There is one in Norcal right now, but it's down for a refresh. Along with the refresh, he is doing a LS7 head upgrade too. Can't wait to see it in action!

There is a 447 CI motor on the C5R block, with the C5R heads, see www.blackattackracing.com.
Fastest run was 9.46 in the quarter mile.

We have a couple large cubic inch setups coming together right now hope to have some results soon. A 436 with our L92 sheetmetal. I would suggest calling steve at race engine development, for a LS2 block with replacement Ls7 sleeves and a larger stroke for a 447 or 454 combo. That will make some killer power.

right at 600. We have a new motor setup coming very shortly that is going to blow everything we have done before out of the water. It will be going in our next pro-touring camaro that we will be starting on. I hope it will be the foundation for results for all the new parts/blocks coming out. Keep your eyes and ears open for when our monster motor is ready.
