if you dont mind id like a pic of the passenger side. just going off the pics ive seen i feel like they would work but if not im sure i can make some mounts to work. is that the holley midmount kit? did you paint it or that the black it comes? im waiting on mine to come in and its the black kit.

bruuuuce

Yes, its the mid mount. After reading a few things, I painted the black mid mount housing black. It came flat/satin black. I painted it gloss black high temp paint I had sitting around.



Drivers side pics



Passenger side



lines on the frame rails comparing the stock engine placement to the LS. Well approximate front of engine placement


One thing I am still figuring out is the clearance for the high pinion 60 front axle and the mounts and headers. It's going to be close, but I am also looking for as much up travel as possible, or more. Since I don't have the transmission yet, I can only approximate the driveshaft. To be fair, it was close with the I6 as well.

Also since no transmission I have not done a final fitment of the mounts. There are gaps between the frame and the mounts in the pics that look bigger in the pics than I noticed. Once the transmission is in and I can finalize placement, I'll work on the final fitment of the mounts.

I didn't do an install/build thread here, not totally sure it warrants one...

appreciate that. do you happen to know the distance between the frame and the closest part of the header on the driver side? from what i understand the novak is more set to the driver side and the holley to the passenger. if theres atleast 2-1/4" it may work with the novak mounts.

Ill take some measurements in the morning. Thinking 2-1/4 is easy

DuckHunter5.7

yeah it looks like it has plenty of clearance to the frame rail. im prolly gonna give em a shot if i can wait long enough for em to get back in stock. i appreciate all the pics they help.

Tried to get some pics of the tape measure. Again, I am not fully welded in and no transmission to make sure of everything. Body is off, bla Black bla

The engine appears to be about 1/2 off set
The back of the engine to the frame on each side appears to be about 8-3/4. Not sure if the block is symmetrical where I put the tape...
Front of the block is about 8" DS and 6-1/2 passenger side.
pics for reference





I still need to change from the truck pan to the Holley pan. It appears after I do that the oil pan will be about even with the frame. This should make the skid plate easier.

Measure from the crank bolt to the frame as close as possible.
Symmetry issues alleviated.

bruuuuce

the front is about an inch to the passenger side, measured as above. but again, noting is in place yet.

I was just following up to see if anyone has used the headers with Novak mounts. Mine was just thrown together and stupid restrictive, dual 2” to single 2.25” and just ready to get a better system after 2 years.

bruuuuce

a couple recent pics, got delayed with other projects, for those that are interested. for reference, LJ chassis and Tub, no body lift, 6.0 and 4l65E.


ill probably massage this area a bit


view of the headers with fenders on and hood mocked up.


the exhaust, with no body lift and a UCF virtually flat belly pan. I may drop the tranny mount down 1/2 inch or so transfer case clearance, so this could change.

XCRN

Ill respond to my self. I decided to buy the headers and full exhaust and they do work with the Novak mounts and no body or suspension lift. They do take up more room in certain areas and free up in other compared to other header configurations I have ran.

Toddoky, sorry to bump an old thread but I was trying to find and order the headers that match the engine mount, and cant find them anywhere, seems they are out of production.
is this true?

user 4737373

Yes, they were obsoleted by Holley along with the majority of all their other engine swap headers.

LS1 TJ

Don't know if this helps but on my 98 Wrangler LS6 swap I used 1 3/4" block hugger headers.
