Marks v8 swap kit needs (1 Viewer)

[Skycap17]

Hey all,
I have a 77 Fj40 with the factory 2f and 4 speed transmission. I recently found a marks conversion kit used for the right price (bell housing, shaft, jump shaft and a what appears to be a throw out bearing). It didn’t come with the flywheel or clutch. I’m wondering if anyone has info on what I can get away with running? Can I just use a basic 168 tooth flywheel and standard 11” clutch -pressure plate assembly for the 93 Chevy 1500 I robbed the sbc 350 engine out of? Adv adapts shows their stuff but discription is a little limited likely because they don’t want to do the leg work just to not sell their parts. Any advice?

Why are you converting? Is the stock engine running? Does it run well? If so I suggest leaving it in the Cruiser.
Nothing against V8's as that is what is in my 1970 FJ40 but I did the conversion because the six was scattered along a section of I-10 east of Indio Ca.
The eight has worked well for years but there have been times I wished for the six.

I would contact Marks. They have both 168 and 153 tooth kits.

I’ll make you a heck of a deal on a fully functional needs nothing but a carb overhaul outfitted with California emissions already

I don’t think I have time to wait for marks. I think covid 19 is going to cause our state to shelter in place any day so I’m wanting to just go up to Napa and get what I need to do the job while I’m stuck at home for two weeks

Then just take a shot at it. You can always take it back if it doesn't work.

As far as being quarantined, you can get parts on line still.

Not telling you not to do the change over just think before you leap.
Back in 78 I had a real nice 283 I was going to drop into my FJ40 simply because that was what I read about in the 4X4 magazines but decided to wait until after my wife and I took an almost month long trip.
I drove the Cruiser pulling a 16 foot Breeze travel trailer from Riverside Ca. to Phoenix Az. up to grand Canyon over to Yosemite to the coast at Eureka Ca. down 101 back to Riverside.
We would drop the trailer and explore at just about every camp site.
It was a hot summer and going up that stretch from Phoenix to the Canyon which is a gentle grade all the way we passed a lot over heated cars on the side of the road and that six just kept chugging along and the temp gauge barely getting above 195F.
I got home and sold the 283.
In 84 with 210K the six lost #2 piston and due to expedience, logistics and cash flow I put in a stock 350 from a 75 Belair.
There was a marked difference in top end power and the 40 will go faster than anyone in their right mind would want to go but the rig doesn't crawl like it did with the six.
With 4:11's and 31" tires the eight will go faster but it is really winding out so I still keep the speed at 55 to 60 mph.
Back in 94 I rebuilt the V8 and at the time considered looking for a six and while I had the time and money didn't want to do all the work it would take to chance it back.
Now even if things were going smoother in the world it is too late in life to be doing all that work plus the V8 has now been in the Toy longer than the 6 was.

The 350 has more torque than the 6 cylinder, at an even lower rpm, sooooo don't understand how the 6 cylinder was a better "crawler".

4 inch stroke. Could lug around in high range slower than a lot of other four by's.
With the 350, have to put it in low range.
I can see we might have a debate on this but I have driven my 40 with both engines and there is a difference.
There was things I liked about the six and there are things I like about the eight.

Thanks for the input.

All great info but I’m already committed to the v8. If one of you wants it, I’ll make a deal on a good running 2f aside from an overflowing carb.

Just to reiterate: I’m looking to see if anyone knows if I just need a standard Chevy 5.7 168 tooth flywheel and clutch/pressure plate or if there is something different about the Marks conversion that forces me to use only the Mark’s parts. Would also be interested to know if I have to get a gear reduction starter or if hugger headers will fit around the factory starter

1. Don't use a regular Chevy clutch, they require more travel to fully disengage than your Landcruiser hydraulics provides. Use my custom built Chevota clutch, message me if you need more info on this.
2. If you don't have your motor mounts yet, I have reconditioned Chevota motor mounts (at a savings) in my ebay store, lemme know

I have personal experience here with what Jim is saying above. My previous V8 FJ40 had a VERY poor homemade clutch set up from the previous owner. I drove it until it failed, then spent an embarrassing amount of time trying to source the parts only to find out they were incorrect to begin with. I reached out to Jim, from previous experience I had with his company in the late 80's and had my 40 back on the road in a week.

I used a chevy centerforce clutch and pressure plate

 

[pbgbottle]

Didn’t marks have a couple different setups. One was a fat flywheel to make up the distance and another later setup I think he used regular flywheel and a longer spud shaft setup. I use the low profile Chevy clutch
Lol. Fenco brand #CA5473. It’s a special Chevy low profile pressure plate
