I just gotten done installing New Poly Busking kit in my 86.

Not bad just takes time the hardest part for me beside getting out of bed to get it done.
Was the aft upper A arm Bushing The Kit I Purchased this bushing is 1 piece you had to press it in I found using a hose clamp to help compress the flanged end to make it a smaller OD help get it going in to the A arm.

The rest of the kit everything was a 2 piece type replacement bushings very easy to replace.

For removing the old Rubber bushing a 12 ton Harbor freight Hdy press on sale and a propane torch used some sockets to help press out the old bushings.

Oh ya very messy the grim of the 1500000 mile of road grim on it.

I Love my Air tools a Air Impact to remove just everything put eveything back by hand and Tourqed everything to specs.

It took me 2 full days to do the job + I had to remove the batwing to reseal the rear end cover due to it was leaking oil.

On a scale of 1 to 10 I give it a 7.

For me pulling and reinstalling the 700r4 trans was easyer LOL.

Went for a 100 mile cruise I can say WOW.

Much nicer ride feels much tighter I am Happy with it.

I think the red Koni Shocks help out also.

I still think it the Idel Air Contorl Valve (IACV).

New dont mean it good.

I took it out and cleaned it, it was covered in carbon on the tip... but would an IACV cause a misfire throughout the entire rpm range and cause sluggish performance? I am talking super sluggish, it has that "tired" motor sound.

Yep I had that issue after I put the new motor in my car.

I think it was $40.00 at Napa.

My car ran fine when I first put the motor in i was cruising around the block then out of no where it stated acting up.

I chased it for a while put a new AICV in it fixed.

youve got me scratching my head, why would you go with smaller port heads and a longer duration cam?

now I can see the smaller heads IF your goal was more low rpm torque or the larger cam if the goal was more peak hp, but going for longer duration cam and smaller port heads potentially hurts both ends of the power curve, with zero gains
