This forum doesn't seem to get a whole lot of activity so I figured I would post the build I've been working on.

Its an L86 out of a 2020 Escalade and it's cleaning up well. Will be replacing the big block in my 68 camaro.

Relatively mild setup.



GPI SS3 cam
BTR .660 springs
C8 intake
Stock heads
Trunnion upgrade on the rockers
Morel lifters
Holley LT oil pan
ICT Valley Cover


I'm hoping to run a Holley Terminator ECU. They dont officially support larger fuel lobes so I need to look into that.

Anyone else working on a Gen V swap?

I’m planning to install an L86 and 8L90E in a 46 Chevy pickup in a couple of months. Going to leave it stock.

The Terminator X Max V2 is an excellent option. For the power that you will be making, I don't see a need for larger fuel lobes. I don't know this for a fact, but I suspect Holley will have support for larger fuel lobes in a future firmware release.

Hey Andrew, thanks for the info. My hope is that Holley will have support for fuel lobes by the time I'm ready to make that purchase.

I totally agree that the fuel lobe isn't really needed for my application but it seems like most Gen V cams are starting to come with a larger fuel lobe as a standard option. Not a lot of info on tuning DI setups with Holley but some of the HP tuner guys say they dont change anything for the larger fuel lobe. The fact that Holley has a disclaimer in the software about not supporting larger lobes makes me think that there may be more to the story. Just have to wait and see or worst case go with a different cam.

agree, not much traffic on this forum lately. LT swap info is sparse. In the old days, there would have been a couple of dozen guys building cars and doing swaps.

I'm swapping an LT4 into a 69 camaro. Decent general info out there but not detail like you get when following a swap thread. LS swap threads were all over the place 10+ years ago.

Is there another resource out there? FB and IG are such ridiculous mediums for following a swap. or maybe I'm not using them correctly.

Are there any detailed comparisons between the Holley/Wegner/drive junky front accessory drives?

I can tell you that the Holley midmount is very well engineered and is available for Gen 3/4/5 and LT4/5. I just got one for my GTO update.

Yeah you really have to sort through the junk on FB and IG. Youtube has some good info but it still takes some searching.

It looks nice. What are the advantages over wegner and Drive Junky? DJ touts being the only one to drive the supercharger directly. Holley's claim is keeping factory supercharger belt routing plus a strengthened PS bearing.

I don't have direct experience with the Weaner or the DJ drives. However, just looking at the Weaner drive you can see that they mount the AC and the alternator up high on either side of the engine.

The Holley LT4 drive mounts the alternator down low and tucks the AC compressor tighter to the block.

The DJ is different still and has the alternator up high on the driver's side and the AC down low on the passenger side.

All drives seem to have good belt wrap on the supercharger.

Given the different configurations, I would think the best one is the one that fits best into your particular chassis.

When evaluating drives I always compare power steering pulley belt wrap along with supercharger pulley wrap and number of belt ribs. Quite a few of them come up short and can lead to squealing/slipping belts under load, both supercharger and power steering imho.

Here’s mine with a 10 speed. Tuning is a fun challenge with the gen v.
