Re: 6.0 LS2 swap in 67 Chevelle

So I did the driveline angles on my 67 with a magnetic digital angle finder. I have 5.5 degrees down on the trans, 1 up on the pinion. The trans is not forward at all and is touching the tunnel, even at this angle. I bought new UMI adjustable upper and lower rear control arms and dirty dingo engine plates. Going to likely go with Holley 302-2 pan and the Holley mounts? What do you guys recommend considering that the guy who did this early swap used a energy suspension kit, but welded on new frame mounts??? Just want some opinions before I buy parts that donít work well together.

Thx

Re: 6.0 LS2 swap in 67 Chevelle

If you are going to start swapping mounts/pans Iíd just go with all Holley stuff. Itís a proven system and top notch stuff.

Tighten it till it strips and back it off a quarter turn.

Obviously you need to move the engine toward the front. I would take some measurements to see how far the engine is from the firewall.

I think the Holley mounts will move it forward and fix your problem. I used their mounts, oil pan and headers on my Camaro. I didn't have to cut the tunnel for a 4L80e trans.

Re: 6.0 LS2 swap in 67 Chevelle

Definitely go with the Holley mounts and oil pan. This solves driveline angle problems, floor pan clearance problems and possible steering arm problems at the front of the oil pan . . . at least on an A-body.

I measured and have about 2.5Ē from the back of the drivers side head to the firewall.

You can’t go wrong with the model specific Holley/Hooker parts. It might seem like unnecessary spending since your swap is “done” but everything will fit better and actually work right. This is coming from a guy with a ‘67 and iron block 6.0L as well. I opted for the rearward brackets but I knew going into it I would need to cut the trans tunnel for the manual trans anyways. Depending on what trans you’re running, the forward brackets may require little to no tunnel mods and still get good driveline angles. Take a close look at the 302-3 oil pan though. It will provide more tie rod clearance on our cars than the -1 or -2 pans. Oh and welcome to the site (pics are always welcome!!

My research has lead me to go with the forward Holley mounts and the 302-2 pan. Iím running the 4l60e trans that came with my 2006 ls2 create package. I want to avoid cutting the tunnel up and if a forward mount and only slight clearancing of the servo will do the trick so be it.

I think you’re on the right path. And I may have been mistaken earlier on the oil pans. I think it’s the 302-1 that the A body cars should avoid due to tie rod interference. You should be good to go.

Re: 6.0 LS2 swap in 67 Chevelle

Yes the 302-1 was their first run, won't work on a-body. The 302-2 is the one to go with although pricey. The 302-3 has added drain bungs if you're going to run turbos.

Make sure you have room between engine and fan/radiator before you move the engine forward. Check exhaust routing, wiring, and transmission linkages. You will have to either get an extended yoke or have a new driveshaft made to cover the length.

Before you go swapping in $$ parts, look at what you have. Is there any way to slot the engine mounts to bring the front the engine down? Turn your steering wheel full lock and look to see how much room you have between your inner tie rod end and oil pan. That's the room you have to work with.

I had to shim my trans crossmember to clear exhaust and also to try and correct my working driveline angle. I used stainless spacers I picked up from the local home depot. Not perfect, but they're working fine. Just like these:

Re: 6.0 LS2 swap in 67 Chevelle

Agreed but unfortunately I just do not have enough oil pan clearance to go forward and with the aftermarket welded frame mounts, sits just too high. I could re-fabricate the welded frame mounts amd lower the engine. It think that would fix half the problem, going forward that 1-2 inches will help greatly as the motor is pretty tight to the firewall currently. Going to go with the Holley stuff and with the UMI rear control arms I installed today should be able to dial in the driveline angles.

Re: 6.0 LS2 swap in 67 Chevelle

I used all Holley stuff except for the crossmwmber, since I boxed the frame, on my 67, and it all worked out fine....

Re: 6.0 LS2 swap in 67 Chevelle

Awsome! Just need to save up some cash and get my parts. The question will now become if I do headers while Iím at it, plan on going to a 2.9 whipper in the near future and might as well get ahead of the curve.

Just be sure they all play nice together. The mounts I have did not with the hedman headers I'm running. Had to push the engine almost back to the firewall to make everything work.

Thatís why Iíve decided to go with all the holiday stuff. That way the headers will work verses mixing and matching manufacturers. It seems their stuff allows the engine to sit lower in the frame allowing clearance for the Whipple down the road.
