93 1500 w/ 5.3L & 5 speed swap

[92cheyenne]

I just blew the 4.3 in my 92 1500 and It has a 5spd trans, I've been doing alotta research and some people say the 5.3 wont work with the nv3500 trans but based on what I've just seen i guess it does work. So all i need is a 4.8 flywheel and different pilot and throwout bearings and it will mate up to the 5.3?

Also,Im getting a 5.3 with ecu and harness included, since im using the ecu that came with the 5.3 do I still need to send it off to be reprogrammed?

Can I use 5.3 motor mounts?

Just want to cover everything before I start spending money.

Any help would be greatly appreciated, I'm 19 and I know alot but I still have alot more to learn, this will be my first engine swap.

Yeah you will need the 4.8L flywheel and clutch kit. Also the throwout and pilot bearings listed previously.
You will need to have your PCM tuned or it wont run. You will also need to buy LS to SBC adapter motor mounts. Can be bought cheap on ebay even.
Good luck!

Another question, so once I get everything in and put in the tuned 5.3 pcm and connect the wiring harness to everything, am I done with wiring or is there more to it.

Thanks. Its going to be a DD so gas mileage is a must. Thats why I havent swapped cams yet either. Not a race truck by any means.

yeah, same here


...but the more i think about it, a 212/218 high lift on a 112* sounds really nice right about now.

good thing i've still got tons of crap to do on the vette to keep me busy for a while!

Got some minor things done last night.

Ran the steam line from the heads to the radiator. There was a screw in plug just below the overflow line so I threaded in a hose barb. Should work fine.



Also undercoated the wheel wells and frame.


All I need to do is put on the tensioner and belt and should be able to drive. Maybe I'll get some vids this weekend!
