L92 swap
L92 swap Im finally tired of deal with my continuos issues with my LT1 and have gotten to the point of not even wanting to work on it anymore. I know that's a bad excuse but I think I'm going to the the other side with the L92.
Has any of you guys done this swap? If I were to get a L92 long block what would be needed as far as for the wiring and computer? I know what modification needs to be done as far as motor but needing info for the other parts.
I know this is a LS but it's going in a LT car.

If you can't keep
up and running how on earth do you think you are going to be able to handle a swap of this magnitude?
If you lack the experience to be able to troubleshoot what you have and get it resolved I think it a very bad idea to try and undertake this. What you have now is nearly stock and relatively simple compared to what you are looking to make it.

That's the old setup. Never updated. Having a lot of issues with machine work, heads being brittle, along with poor quality work done by different shops. Found a new builder and have been doing research for a while. Obviously the car has been down for a while. 100 miles have been put on it in 4 years. A lot of damage that was done to the engine was done by previous owners and was unknown untill it was to late. So I basically need to buy new things to get going in the right direction and just decide to go a different route. I actually have a good paying job now and will not be going to no name shops for my work. Those were bad decisions made then while trying to rush. Car has just been sitting in my shop and I'm tired of looking at it. It's time to drive it again.
Forgot to mention car still has motor in it right now but everything else in out. No interior, interior harness, engine harness, dash, and computer all all out. So it's ready to just drop k-member out and start parting the whole drivetrain (front to back) everything is getting replaced.

I know you said that its the machine work and all the problems with that, but if its other issues your tired of i.e. optispark, i know alot of third gen guys have taken the tpi computer and harness and put and HEI distributor in the LT1. just some info i thought you might want to think about before saying goodbye to the lt1
Excellent choice!
You will need the harness and pcm obviously for a 58x motor.
Easier to use a cable drive tb. SLP has been selling stock ls3 intake manifolds with fuel rails and 42lb. Injectors on ebay. Ive alredy go from em for less than 400$ shipped
Trans, depends what you decide on, will need parts for that.
Tubular kmember with ls mounts and lt rack location, unless swap to ls rack.
Fuel system. Depends if want to run return fpr or c5 fpr/filter.
Just so many ways of swapping now adays

Been looking into th400 and dana60. Haven't looked much into which route fuel system I'm going to run yet. Cable driven is the route I'm going. Going to install aftermarket blank dash and run all mech gauges. I will run manual rack as well. Thanks for the useful info on the intake.
The distributor was an ongoing battle for a while but resolved those issues. Just looking for a change.

Th400 will bolt right up. And all u need is a the flexplate and a sbc tq converter with extended mounting feet or shims. No longer need spacer. Since the gen 4 ls motors have a thicker flange than gen 3 24x. The l92 has the better rods, pistons and rod bolts. If afm or Vvt, it's easy to and delete those parts. I found a non afm or Vvt l92 recently. Had basic ls2 timing cover and not Vvt cover.

the_merv and MattSapp95T/A have done the swap, 97badass and myself are in the process right now. 1961ba427 is also a good source of info.

Everyone realizes that L92 is only the head correct? And the LS3 with L92s? The LS3 and L92 head only differ in the fact that the ls3 has hollow valves. The motor you want is actually called a LY6. Its a iron block 54 tooth wheel with the L92 heads on it.
It would be easier to swap the LY6 into the car because the LY6 motor comes with the l92 heads instead of starting with the LQ4 engine like I did then switching everything to LS3 top end.
