LS3 with a 4L65e

[andy49]

Is there anybody out there running this combonation, I haven't made the swap yet. Looking to use the 480hp LS3 crate motor with the ECU controller. I have the LS6 now and going to sell it. Wanting to switch it up.
Thanks,
Andy

I'm running this setup in my '55 Chevy with one of our turn-key LS3's. The down side to using the GMPP engine controller is that it won't control your trans, so you'll have to purchase an expensive stand-alone trans controller. Not sure how much you're looking to spend, but we offer LS3 turn-key engines starting at just over $11,000. That includes a custom-tuned ECM and custom wiring harness that can be built to control your 4L65E trans no problem. We don't charge any extra for those customers that need a TCM to control their auto transmission as well. We also offer various options for front drive accessory kits:

We've done a lot of connect and cruise swaps with the LS3 and 4L65e. It's all a well thought out system.
If you're doing the connect and cruise, we have an instant $500 rebate going on with them.. PM or email for details.

Thank you guys, good Info, I will be calling. I am really wanting to swap my Ls6 for the Ls3, I want to keep my tranny and accessory drive. Sounds like it will be a go, I'm excited. Tks.

Yep just as long as your LS6 is a Corvette serpentine drive rather than an F-body system it'll all work out the same!

Hey Trevor can you tell me the lobe separation for the cam on your 600hp 418 engine package?

[Trevor @ Texas Speed]

Hey Trevor can you tell me the lobe separation for the cam on your 600hp 418 engine package?

Yes sir! The cam for this package has 228 degrees of duration @ .050" and has a 116 LSA. This package is built to have a relatively smooth idle with minimal lope, and it will work easily with a stock torque converter, if you so desire. This particular package will have 10.9:1 compression ratio and use the Precision Race Components ported factory GM LS3 head castings. The 630 HP 418 CID will have 11.25:1 CR, a more aggressive cam, and our PRC 260cc LS3 aftermarket cylinder heads. With that said, we can mix and match any package that you'd like. So, for instance, if you wanted to run the PRC 260cc LS3 heads for some additional power but use the smaller cam in the 600 HP package, we can certainly do that. We can custom-tailor any package any way you'd like!

Let me know if you have any other questions.

Thanks!

Thanks Trevor. You guys get my vote. I will be pulling the trigger this spring.

Sounds great! Let us know if we can help you in the selection process.

One option for you for this combo is to have the LS3 built with a 24x crank and use a 1x cam sensor and use the wiring harness and computer from your LS6. We purchased a 418 LS3 short block from Texas Speed last fall to replace a blown up LS1. We had it built with the 24x crank so we could re-use the wiring and ECM from the LS1. The combo uses a built 4L60E behind it.

There are lots of options available to you and any of the vendors that have already responded can help you sort out exactly what you want.

[Trevor @ Texas Speed]

Totally agreed. My '55 Chevy has an LS3 with 24x reluctor and DBC setup. I purchased the car with an LS1/DBC setup with the 4L60E in place, so this was the easiest route when I decided to upgrade the engine. I prefer the DBW setups in my cars, but I would've had to replace the harness to do it in my '55. As mentioned, lots of ways to get to the same result!
