Trailblazer torque converter

[iamdub]

Circle D makes a stock size converter for the 4l60 that they suggest for SUV’s and trucks. It also comes in lower stalls than most “performance” converters. It would probably not be a bad idea to contact them with what you’re looking for and what other mods you’ll have and see what they suggest.

I've come across Chris's posts many times while researching this, but never bothered to shop their site because the whole reason I'm sticking with a stock cam is to invest only what's necessary into this setup. Holding back a snowball here...

Sounds to me like you could use a little peer pressure on this one. You do want to be cool, right?

I never knew it was a common issue, but I've never had a reason to investigate. I'm glad to hear that it's a possibility with a simple and cheap solution. I plan to have someone work the throttle while I watch the pulley.

Stock L33 cam. Same specs as my original AFM cam, but without the AFM lobes. Yes, it IS painful for me to go this deep and keep it stock. Please don't chastise me as I'm still working through this. It's a logical need-versus-want decision.

Well that’s no fun.

Nah. I'm content with just being weird.

I know, I know. It's not cool and no fun having to put on my big boy undies. But I'm investing in the future. The less I dump into the 5.3 now, the more and sooner I'll be able to invest into a 6.0 or 6.2 swap. What if I find a smoking deal on a 6.0+ a few hours away? I'll need my current 5.3 to reliably get my trailer, tools, and a friend and I there and back.

I'm skeptical. Fun, cool guys don't usually use words like "invest" or "future."

You're killing me, Smalls.

I think I’d do an LQ9 cam at the very least. I recall it not losing much down low if at all but gaining up high. There was a hotrod article about it somewhere.


Edit: here you go. Even has your cam you want in there. https://www.google.com/amp/s/www.hotrod.com/articles/ls-cam-test-comparison/amp/

Twisting that knife, bro.

I had an LQ9 cam laid up in the shop from my S10 build that I finally just sold cuz I didn't think I'd ever have a use for it. I've read that article a few times since trying to get an "at least" cam. I think they screwed up, though. The chart they posted for the LQ9 cam is identical to the one for the LS6 cam- specs, results... everything. A friend swore I should use an LS6 cam but everything I read about an LS6 cam in an otherwise stock 5.3 showed a noticeable low-end loss and appreciable gains only near redline. Regardless of people's seat-of-the-pants feels, the cam specs show that it would be all top-end and you can't argue with physics. If the LQ9 cam is any similar, even if milder, then it's still not worth it to me cuz this fat pig needs help in the low-end. I'm actually willing to sacrifice a little top-end if it means more off-the-line grunt.

I'd want a tune to optimize a cam swap no matter how small of a change so that adds to the cost. I see it being more of a waste to get it tuned for such a small cam since it's more investment into something I don't really ultimately want.

Besides, I already scored an L33 cam for right around $55. Once the motor is back together, I can turn the key and go as-is, no tuning necessary. And when the times comes for the 6.0+ swap, the 5.3 would be an easier sell with it being "stock".
