LS headers (1 Viewer)

[matzell]

I posted in a thread in the 40 section, but getting little traction. Is there another option besides the Sanderson block hugger headers that work in a FJ40? WOD sells some raw ones with a v-band collector but I have been quoted $350 to have them coated. I do not want $900 headers. I looked at there stock flange coated headers and they are in the $600 range.

Any other options? What is everyone using these days? Makes the old 350 rams horn manifolds look pretty good right now. lol!

camaro driver side & c5 pass side is the best I've seen thats easily found and less dollars. thats for a framed 40, a tube chassis would have more options.

These are what you want. I used these on 40, 60 and 80 series and they fit like the best out of anything.

They sell them uncoated (linked) for $221 shipped, or coated in black or silver for around $350/pair. They also sell them with ball/socket instead of bolted flange but I prefer the bolted flange.

If you are using a Cruiser clutch slave they will point right at the hose but what I have done is convert to internal hydraulic throwout or basically relocate the soft hose by running a hardline from the slave cylinder up the back of the engine and run a soft hose over the manifold.

On an LS the rear dump makes the starter and slave( if manual) a real PITA for packaging in a 40.

Do you have any pictures of these installed in a 40? They look a lot like truck manifolds

I dealt with this on a 60 (same thing) by bending up a hard line coming out of the slave cylinder and ran it up the back of the motor and mounted one of my stainless brake tabs to the back of the cylinder head.

On @Toler 40 with an H55 I had him run an internal throwout bearing.

Saving this post so I can remember to ask you about it later.

Interested in how this was achieved

yeah, I went with the camaro on driver side to give more room for the collector too. I used the rear dump pass side and the exh pipe has to curl raround and it just barley blocks 1 starter bolt.

Got any pics?

Won't work on a 40 with Mark's adapter. It shifts the whole drivetrain toward the p.s. I tried those and had to return them. There's zero clearance with the p.s. framerail

I did the Advance Adapters headers - Vortec Gen 3 Universal Headers /Ceramic Coated - https://advanceadapters.com/10703. They're nothing special, but they work. They fit inside the frame rails.


Best pics I have handy right now.

how does the adapter shift the drivetrain left or right? that sounds like a you problem, I have two 40's here right now with these manifolds installed and they fit better then anything else I have tried (which has been just about every option)

Maybe it's a you reading problem? Any of those 40 conversions use Mark's adapter? The kit has spacers that go between the adapter bellhousing mount and the factory bellhousing mount on the drivers side and a shorter bellhousing mount for the passenger side.

I'm just out here trying to help a dude in case he's using this adapter, no need to be an ass. Weird, you were so nice the one time I met you in person but so aggressive on the keyboard.

is Rob actually using that adapter? I've use the Marks adapter a handful of times into 60's but not a 40, however if I don't get why that should need those spacers unless it's to clear a factory steering box, but is anyone actually running a 40 steering box in this discussion? Rob has a Saginaw I believe.
I like to keep the engine and drivetrain in the original latitude if at all possible

Anyways. I'm sorry you took it that way. I will post up some pictures on Monday but they work great for me

I'm really not sure which adapter, tbh. I just know the Marks kit that comes from AA uses the flywheel housing adapter, factory bellhousing, and spaces it over. That gave (barely) enough room for me to sneak the steering shaft beside the d.s. manifold to the Saginaw box. I imagine if it wasn't shifted over with those spacers, it'd been even trickier, but I guess choose your poison.

I used that kit so I could keep the transmission and tcase in the same location front to rear and not have to scrap the trick skid plate and rear crossmember I already had. I know others choose to go a different route for a myriad of reasons. Trust me, I liked those manifolds and had them in hand trying to make them work, but there's just no way to sneak a ps dump rearward with this configuration, unless you hang it lower than the frame rail and I know nobody wants that. That's why I wound up with the modified C5 manifold and jogging the ps under the oil pan and then back to a collector on the d.s.

I am running a regular AA bellhousing to a H55f. I have not played with it much but have looked at the mesurements of the Hooker manifolds and they will not clear. I am still up in the air on what I want to do. I need to drop the 350 in my 77 and get that running first. Those Ramhorn manifolds on that are the cats meow! I would love to have something like those for the LS. Sanderson is looking better and better.

The summit manifolds fit great on @Toler's 40 with an H55f and AA bellhousing, positioned so the 60 H55f shifter came out of original 40 tunnel hole. Maybe he can post some pictures.

I am half tempted to buy these off Amazon and give them a try. If they do not work I can return them. Anyone ever try them?
