the bumpstick cams from Urge seem to be the real deal. I'll hopefully be testing some this spring.

And as far as the JB weld. I am going to pull the pan again and use a 2 part epoxy on the bolt to get me through next summer.

So I guess I'm answering my own question. Build it and build it right. The revs are fun but it's not the most important thing I would like more torque so again I've answered my own question.

Thanks for everyone's input. Sometimes you just need to discuss things with others to go in the right direction.

He's been running that 2.4 for a little over a year. Thing is a rock. It's purely a track car and it makes 30-40 hp over a 2.2 with similar bolt ons. The 2.4 can make 250hp at 8200 rpm. No need to spin to 9k. The intake is already choking the 2.4 at his redline. More RPM isn't going to fix that.

i guess you have to ask what's the power goal or is it an RPM goal?

Maybe I can get another 10-20whp out if E85 and BC/Skunk2 cam install.

My last track day and a good read on how the car performed amongst others. I ran Group A which is the last section of the article. They say 2.5 but my car is a 2.4

Reliability really comes from your engine builder knowing your build and what your intentions are, a good engine builder and tuner, if given the OK to do so (budget wise) can put together the right components for an amazing stroker motor with as much reliability as you want withing reason. When we built my motor i was told i had the worst rod to stroke ratio they had ever seen and that it wouldn't work. I have over 45,000 miles on this motor, and i have never had one engine issue, and i am not nice with it....we also revved it to 10,500rpm on the first dyno day...i have the limiter set to 8500, as it stopped making power in that 8500-9500 range and did not see a reason to ever go that high again.

be confident in your investment if you have the right people doing the work...

Thanks again to Rick Rollert, Jeremy Allen and inlinePro!!!
