this weekend [sm=icon_rock.gif] I'm tearing down my motor to swap the following... Plenum gasket (APS precision aluminum plenum plate), timing chain (double roller), most likely the water pump, and both heads (R/T 1.92's non-ported). I'll also be having my intake modded to shift the powerband up to 4500~5000 rpm at it's max (not sure if I'm gonna do it or send it out since I only have a few of the tools needed).

I'm planning on taking a bunch of pics [sm=Flahssssss.gif] as I go and if there is enough interest post a "how to" on the swaps being done (water pump, plenum, timing etc).

Snafu... do you still want the gap measured on the TB plate to TB bore? and is there anything else you need? nows the time... I'll take a bunch of pics of the TB if you need them.

Hey Steve-post away im always interested in watching something being done..especially the head and plenum

 

OK,... i'm gonna put my kids to work... (yeah, mean dad lol). my daughter's got the digital camera (age 16) so she can be the photographer and my son is gonna help do the wrenching (age 14), he needs to know this stuff and now is a great time to toss it at him.

 

If it's not a huge deal, could you mic the OD and thickness of the butterflies on the TB? I'm also interested in the geometry of the main shaft, but that's not a huge deal. I don't expect you do disassemble the damn thing just for measurements.

I also ordered my APS billet plenum plate the other day. Should be here the end of the week, begining of next week. I MIGHT get to it next weekend, unless we need the truck to help my brother move. I've been working on my '55 Jeep CJ5 after work instead, that's much more fun.

Good luck on the projects Steve! I'll be interested in the pics.

 

I should be able to measure the bore and the valve thickness but I'm not sure about the OD on the valve, I'd probably have to pull the TB apart to do that but I'll see what I can do.

my APS kit took 3 weeks to arrive, I think they were in the middle of a new run of the plates and that's what the delay was.

 

I got a shipping notice right after I ordered it. Hope it shows up pretty soon.

As far as measuring the butterfly, it should just be 2 screws to remove the butterfly from the main shaft, they're on the underside of the butterfly (I have a stock TB on my desk right in front of me ). Then just mic the OD and thickness, and stick it back together with the 2 screws. Don't forget the loctite though. If you don't get the chance to, or don't want to take it off, I completely understand.

 

are you going to install your roller rockers too>?

 

Oh yeah!!! good memeory, i forgot to add that to the list, but it's on there for sure. Makes the most sense to swap the studs while the head is on the bench.

 

Well, started taring appart the truck last night and did a comp check on all the cylinders.... sure enough, the same head that I fixed the exhaust seat last year has a problem. the #4 cylinder is not building compression consistently and the delta for all the cylinders on that side is too great.

The compression on the other side was excellent, all around 160~165 psi so it looks like that head is probably still good.
