235/242. .621/.615 118+5 ....and I'm using the E40 ECM with 2006 Trailblazer SS OS. The red headed step child of all ECMs haha.

 

Not sure who spec'd that cam but its lacks exhaust duation IMO.

You close the intake valve awful late... but barely open the exhaust valve any sooner than a stock LS9 cam.


Those exact specs with about 10* more exhaust duration would be spicy...

 

Would be about like mine at that point

 

I had Ron at Vegenance spec it out for me. The midrange will be strong with the current one though. I have a few other cam ideas in mind if I don't like this one or it doesn't pull the why I'd like. Maybe use a cam with a some overlap to help cool the chamber down and stretch the intake duration out a little to pick up the lost boost/cylinder filling. But overall I don't think the exhaust duration will hurt me. More cylinder pressure for slightly longer may just help and my exhaust flows pretty well.

 

Used S10 money for new wheels and tires for the Silverado

 

Nice wheels, too bad your yard looks like crap

 

The lawn did take a turn for the worse at the beginning of August for some reason and never fully recovered. Not sure why either but I did make note of it

 

Awesome build. But yah curious as to why you choose the e40? It's kind of a bastard child of the ecm world.

 

When I originally swapped the truck back in 2010 I got a LS2 out of a 2005 GTO so it had the 24x reluctor and I wanted to keep DBW so I went with the E40. So that's what I had when I started redoing the truck. I didn't realize the E40 was such a bastard child at the time or when I planned out the new build or else I would have had the engine built with 58x reluctor. I'll admit I knew nothing on the topic of tuning and still have limited knowledge. If the Holley Doninator allowed me to use my factory gauge cluster then I'd be all over it.

 

So are you a little more motivated to get yours going now?
