Good point.

 

The triple downdrafts look awesome though. Too bad they're going to be covered up.

Ha Ha yes. But in my defence. I got rid of the mikunis because over here it is really hard to get parts and jets. They where originals off a toyota so I would have needed to buy jets and new venturis a new accel pump housing.
Irony is I sold my DCOE to buy 3 new carbs. I COULD have run twin side drafts one sweeping over each rocker cover. Manifold would have been easy and I would have only needed to buy one more carb. Tuning twins in that situation would have been interesting though.

Yeah, those Toyota carbs are crap anyway. Like you said, too hard to get parts for.

I have come across a couple of stuffed '74 620s with the king pin front ends. Does anyone know if the actual chassis is the same through to 78? As long as cab mount and suspension pick up points are the same. Got some crazy ideas for down the track. Save me having this one off the road again while doing the mods. Can just swap everything once done.

Yes I swapped a '73 cab onto my 77 truck and everything is the same.  Its just a bunch of bolt-on suspension changes up front.  Unless there's a change in the upper control arm mount - in my truck that's all modified.  

One change is the fuel tank mount - cab versus frame .

Your sir, are doing a mighty fine job! What alternator bracket and tensioner are you using?

Thanks for the feedback!

Its the alt bracket that came on the pathfinder. I had to cut it up and swap it from rhs to lhs to clear the steer box. 3 bolt holes lined up and the alignment was spot on for the belt. The adjuster is the original cut up and modded to suit. It was a pain in the arse. Ended up working well. Bought a new belt to suit.

Yeah from a quick look it appeared as though thefe was differences in the Top fca mounts. I suppose its only an issue if i leave it standard.

Not quite done. The sealing surface for the carb plate to the bottom of the filter box needs doing. Its on a totally different plane to the carby tops. Need to put some strengthening ribs in the filter box too so it seals better.

Linkage bits arrived from UK. Good kit. Welded new lever arms to the standard ones. Need to make a link to go to the centre carb lever. Going to try use the cable cam that came on the throttle body efi. So the throttle feel is smooth and progressive. Need to spin up a shaft and make up a new lever arm to go on it as well. I want it in 2 seperate pieces so at idle it has no load on the cable and it disconnected then takes up as you push the pedal, that way i know the linkages arent going to effect my tuning. Still thinking on the best way to do that.

Had one last day yesterday before i went back to work, had the engine in and out twice to get the extractors right, they had pulled when i welded them iut and the the "fix" was to much and had to adjust them again.

Drivers side was really tight but ended up being the easiest
20180108_162110.jpg

Passenger side just fought me the whole way.

20180108_162046.jpg

The initial reason for pulling the engine again to adjust the extractors was because it was hitting the UCA and the engine wasnt centered, i couldnt finish the air filter box. I got side tracked looking at the monstrosity of a sump on this pathfinder engine.

Plus it only holds 4lts and i need to cut 3in off the bottom

V1.1 holds 7lts. Need to do some thinking about a windage tray and baffles. Going to build a crank scraper in as well but not sure if it is needed, or will work with the girdle. I have 7 days work now so i have time to think about it.
