4.3 vortec

I run a 4.3TBI w/R150. Do not use NWOR stuff, sucks. Largest rad you can fit. Leave good clearance for the distributor (if it has one). $ander$on headers. Jags That Run speedo convertor. Everything is one-off regardless of how vendors say it will fit together. Be ready to be frustrated and learn loads. IF you planned on 'X' amount of $$ for project you planned too little

Also i did get the VSS from Jags only and im running headers from advanced adapters. My Radiator is from NWOR.

I used an '82 2wd diesel rad, factory 3 row. Howell harness. Chopped up some Astro van tubular headers to make them fit for both sides. Remove the front solid axle torque rod and tower if it's still there. Put the GM computer in the PS kick panel, placed in the Toy location. Would be better up behind the glove box, requires glove box cutting.

I'll try to remember stuff and come back and post about it. It's been over 20 years since I did mine so be patient please.

Did u remove the toy computer?

 

[ferg]

Yes, Toyota computer will be no longer required as it runs the Toyota engine and emissions. Have you talked to a SMOG shop yet?

 

[Bullfrog84]

Nope. I have it registered in valley springs no smog.

I have 86/85 toyota extra cab with 2003 chevy votec 4.3 4l60e its dual case , Howel wireing loom they also reflashed the computer to remove the security crap, custom radiator found on Jegs. I think. and adapters from AA. by the time I was done I could have searched and found a 22re turbo which would give close to the same power. I would never do this conversion again , pain it the ass to smog. Yes its 50 state legal with that little bar label.When you smog they treat it like an 86 truck but to the 2003 standards.Yes your not it a area where you have to smog for now.Last I heard they were going make every smog eventually.
