not if you get the advanced adapters flywheel. the spacer is already built in. and i bet you had to move your trans didnt you?

 

no, i havnt moved the trans. a conversion flywheel with a spacer would probably do the same thing as a flywheel with the built in spacer. they both reach out from the motor to seat the convertor. im talking about a spacer that pushes into the back of the crankshaft. its the same diameter as the inner diameter of the flywheel.

 

About how much would it be for a swap? Sorry dont mean to thread jake.

 

I'm currently gathering parts to do a 5.3 swap in a 75' K-5 with a 4l60e.
With 43k on a stock engine, rebuilt trans, computor and wiring harness from Howell, gear change,rebuit 241 transfer case, and all other fittings and adapters, I'll be around $5000.
I plan on tearing into it soon.

Of course, there's always the unexpected.

 

I'm putting an LQ4 6.0L 4L60E from a 2003 Yukon Denali in a 79 Sierra 2wd and it has been the easies swap. I have about 2400.00 in everything including reworking harness and ECM.

 

Ditch the TBI and 700R4, get a pull out from a LS 4x4 truck and get your self a NP241 from a 90 or 91 burb or blazer with VSS.
I know that the linkage on a 208 or 241 are the same, but you have to be careful to not set the engine back to far, the linkage is not adjustable.
As for a TBI 87 350 having more torque than a 5.3, you need to drive more LS powered trucks man.

 

shet it be sweet to do the 5.3 and 4l60e with the electric transfercase..and just have push button 4x4...

 

I thought about the push button 4x4 and still thinking about it. I wonder what would need to be done to make it work... sorry to the OP didn't mean to Thread Jack either

BUT you would definitely make more power from the 5.3 or a 6.0 than the 350 by far!!!

 

you want a 5.3? pm me for more info. i have a very nice one.

 

To do an electronic T-case you need to get a ford front axle because the t-case is set up for the pumpkin on the passenger side or vise verse. i don't remember witch side the 80's pumpkins were on
