3500 swap questions

[PCGUY112887]

Not to be a smartass but thats not what you said. You said "My wheel is a mm or 2 out further from the engine block and doesn't line up perfectly like Superdaves... however I can not get my crank pulley to go in any further to make the alignment perfect. I am afraid to try to use a breaker bar to really turn the bolt to bring it in more, afraid the bolt may break off or something since a bar a few feet long is required to move it well."

Done

Sorry for the misunderstanding, thank you however.

I will snap a picture when I get home.

Also thanks superdave and bszopi.

A little late, but....

Custom 3 pin coolant sensor FTW!

I just had my machine shop take a stock sensor, turn off the threads, and then re-thread it for 12x1.5 so I could use the stock head hole... I realized I only had the 2 pin one after the motor was together so I wasnt gonna drill and send metal into the cooling jacket.







Oh that was really close clearance on the heater core pipe too... I had to put a dent in it to clear the plug

OK, I baked the paint onto my headers today in the oven... damn it was smelly.

Anyways, I went to put the 3.4 DOHC injectors into my fuel rail, but the little clips that hold the fuel injector in do not fit with the new injectors. Basically the new injectors, on the little edge that the clips go into... the edge is all the way around the injector on the old ones, but it is only 3/4 of the way around on the new ones, and the spot that has no groove is exactly where I need one of the clip "legs" to be.

I had no idea the 3.4 DOHC used different clips... I looked them up on Autozone but they are $5/each and I don't quite see how the clip they show could go on my fuel rail.

Also will this effect me?

Ha, for my CTS all I'm going to do is get a thread adaptor for the 3 wire gen III sensor. But I like that idea though with maching the threads down.

[PCGUY112887]

Em wasas, that is what I was looking for. A 1/4" SPT male to 3/8" NPT female adapter is just about impossible to find.

[wasas9]

hmm that blows. Hopefully my local rinky dink parts house will have it in stock. I still need couplers for my fuel lines because i have way too much extra hose floating around with my setup.

[PCGUY112887]

Anyone with any ideas on the injector clips?

If I can just get ahold of the DOHC clips, will they go onto the 3100 fuel rail?

EDIT - ?

You don't really need clips on there as the fuel rail being bolted down gives them nowhere to go anyway.

[PCGUY112887]

Ya know I thought that... I thought maybe they could be pushed "out" of the fuel rail due to pressure and go into the LIM further than they were meant to, causing a leak at the fuel rail.

Anyone run theirs with no clips? There has to be a good reason GM put them there.

[IsaacHayes]

Scott9999 had leaky injectors until he put the clips on. Of course he was boosted and I think had a FMU.

[PCGUY112887]

Well I don't mind the $12 to put them on there the right way... I just gotta know if the clips are compatible since they gotta be ordered

[PCGUY112887]

I made a post in the DOHC section about the injectors.

So the 3500 started to go into today... ran into a small issue lol. Friend of mine was trying to put in the front bolt on the bottom motor mount, and managed to F up the threads that it attaches to (their in the oil pan actually I believe). The other 2 bolts are in... think it will be fine with just those 2?

Also the bracket that goes between the engine and the tranny on the pass side... yeah it doesn't fit. Doesn't line up to the holes on the 3500. On the 3100, there is 1 bolt way down low on the engine, then a set of 4 up towards the top of the block more. The 1 bolt down low and 1 side of the group of 4 lined up, and the bracket went in there. Well now on the 3500, they don't line up.

[IsaacHayes]

Egads. Get a tap and chase the threads, then hand thread it in and see if it's good. Harbor freight has cheap tap sets. Not sure what that braket on the trans does, just adds more strength? I don't know if my car has something like that...

[3400-95-Modified]

I thought you knew of the rear bolt bosses being different... That has been posted in many other places, and is one of the main reasons I didn't do a full 3500 swap. Too many custom brackets needed...

Yes Isaac your car has that bracket, It connects the transmission snout to the back of the block so it doesn't break off under high torque load.

As far as the stripped hole, yes chase it and pray that it will work... two of the 3 bolts wont work, the bracket willl bend too easily. Someone on bstuff was dumb enough to continue replacing lower dog bone mounts because it would bend the bracket and rip up the mount, untill I told him he was missing the lower bolt in the oil pan.
