6.0 into 98 OBS

[capricefrk013]

Anyone try to use the OBS throttle body on a GEN 3 motor? I see it fits pretty good. The opening is slightly smaller then the gen 3. I was trying to mount the DBW pedal to the firewall and it is too tight in that area so I am now thinking of using my old throttle body and wire in the TPS and IAC to the PCM and stick to DBC.

I'd be interested to see the result of this because I am getting ready to pretty much do the same swap. 6.0 LQ9 DBW going into my '98 ECSB. I was a little worried initially about the fitment of the pedal assembly but I've got a friend with a welder and a torch, so I'm sure we can make magic happen!

It's really not hard at all to get the pedal to fit. I think I was even was able to use the factory holes and bolts. I did cut and weld mine but several others have just bent it to where they wanted it.

Took a ride down to Summit Racing today and picked up the flex plate adapter and bolts. While I was there I walked through the clearance section and found a cold air intake for a Gen IV 6.0 Silverado for less than half the cost of a new one. I will make it work for my setup.

Computer is wired and mounted.


Cold air kit on. Had to move the battery over to the driver side. Good thing I already had a battery tray over there. Removed the battery tray from passenger side as well to hopefully tuck the filter in the corner.

That's a nice CAI

Ya I like that it is all black. It is their black hawk edition. The only difference I have found is it isn't CARB approved.

Well I spent the day working on getting the trans out to put the adapter on the flexplate and I may have inadvertently busted the front pump while bolting the motor and trans back together. I wasn't able to move the converter to line up to the flexplate. It would just rock back and forth about 3/4".

So it looks like I will be blowing apart the 65E and converting it to 2wd via the output shaft of my current 60E and replacing the clutches and steels as well as doing the vette servo and a shift kit.
