The OneLapCamaro complete build thread

[NEVER ENOUGH]

That is awesome. I look forward to reading the progress on this one.
I Read the article in GM high tech performance magazine on this set up.

"Driving a Katech Street Attack LS7 is completely safe-just skip the street tires"

What kind of MPG! Can you get with that thing.

Sweet! How about some specs?

Katech does a complete rebuild of the LS7 for the Street Attack build. In my case I had picked up a relatively economical takeout from an ’07 Z06 that I found on LS1Tech.com which I sent to them to be upgraded (although they can also start with a new crate engine as well).

After doing a complete disassembly and inspection, the block and heads are machined (deck and hone) as required to meet Katech’s blueprint specs. In my case there was what appeared to be (nitrous?) detonation damage that required some additional (head) machine work and a new guide – not a surprise to me as I had been getting the impression that the engine had been used hard by it’s original owner (although to this day he denies ever using spray) - this also required in the replacement of two intake and exhaust valves.

The factory Titanium rods were rebushed (see this thread for more info on that), new forged pistons (11.35:1) with DLC coated pins are attached and then the short block is balanced and blueprinted to Katech’s fairly exacting standards. In the end we installed a Katech Torquer camshaft (and played a bit with the advance) with high speed lifters to keep things relatively civil (although a World Challenge cam may be the next illogical step). The heads were completely rebuilt with new honeycomb high lift valve springs and titanium retainers and the long block was assembled the entire assembly was pressure tested (yes, it was) before Tyler’s Sidewinder accessory drive was installed.

Then it was off to the dyno for an initial break in and a quick check that everything was as it should be. I don’t have the final dyno numbers yet (I may have mentioned that we screwed around with some stuff on the dyno) but on the break in run with the soft dyno program we made 500+ ft.lbs. of torque from 2500 to 6250 rpm with a peak of 560 ft.lbs. at 4800 rpm. I may be able to say more about the dyno results in the next little while as well I have a dyno vid coming which should be interesting.

Thank you James for clear and informative post

I just read this article myself. That should be a really nice power plant for your ride.

Any time Kevin - if I'm out at the shop or heading that way you're more than welcome to stop by. Fire me an email and I'll get you my contact info. Unfortunately, we're held up waiting on parts and for paint to dry so I doubt that much will be going on for at least a couple of weeks.

Nice to see you out thrashing on the most awesome '69 within a thousand miles the day after we get a dump of snow - lol. I'll fire you an email but like I told Kevin, we're kind of tools down for the next week or so. Besides, shouldn't you be out chasing the last of the snow?
