Loosened all the head bolts tonight just as it got dark, so I'm saving the surprise of discovering what'* inside until tomorrow........I can hardly wait....the anticipation is killing me.

I'm still debating how far to go with rebuilding/modding this engine. The old saying, "in for a penny, in for a pound" certainly applies.
I'm afraid to add up all the bills so far.

Suppose I still have a good 15 years to play with it before Hydrogen fueled autos take over.
any plans for forced induction?

The heads are off and the cylinder bores look pretty good. No ridges or scratches.
Heads are in good shape too although the valve stem seals are toast.





Aluminum dual plane intake manifold with 750 CFM Q-Jet ready to go.
Note that I have blocked off the EGR like I always do. :P



I plan on setting it up similar to my Formula. Going for torque instead of mega hp.

Forced induction is not in the plans.
I'll leave that with my Bonne.
This engine will make as much torque as the 3800 with 15 psi of boost.

is that the deepest you will go, or are you gonna take the whole thing apart and clean it? IMO a turbo would be fun, something different with the lower GR, but its your car. Just keep the pics and progress coming.

I still plan on dropping the pan and clean up the bottom end. Maybe the rear main seal.
Won't pop out the pistons. Will probably break open a cap or two just to check the bearing clearances. Maybe freshen up the oil pump.....no...probably will.
Front cover will come off and a new timing chain will be installed with a hi torque cam.
Heads will be shaved for a little more compression.

If I go all the way with the pistons and bore, I will just have to blueprint and balance and the cost will become excessive.
I would only do that with my other Firebird that is in immaculate condition and far more worthy of such treatment.
Next year I am considering installing aluminum heads with roller rockers on it.

I already bought the Hooker headers and this will probably be taken over by my son in a couple of years. Have to save the Turbo project for him.
Besides this Olds engine can only support about 500 crank hp.
NA 400 hp will be plenty.

No pics of progress today.
Cleaning duties only.
Re-tapped all the head bolt holes and chased the threads in all the bolts.
Cleaned off the tops of all the pistons. There was about 20 thou of carbon build up.
Painted up all the pulley'*, water pump and accessory brackets.

On closer inspection, the cylinders in a couple of places show about a 3 thou ridge, so some minor wear but not enough to warrant a rebore. No scores in any of the cylinder walls.

I am going to bring the heads into the performance shop tomorrow to be hot tanked, magnafluxed, new heavier springs, valve grind, bushed, new frost plugs, valve stem height equalized, and shave about 20 thou for a half point of compression.

I brought the old radiator into the rad shop last week. Should be freshened up with a new full row core in a week or two.

Oil pan is next to come off. Wonder what I'll find in there.

Got some Comp Springs for the heads. 105 lbs with a damper spring. Good for 6500 rpm. Ya right, like it will only be turning 5500 max but the original springs a single units rated at 80 lbs.

Crane cam (extreme energy) on the way. It'* mild and makes peak hp at a low 5000 rpm....that'* 160 mph in 3rd gear (no overdrive in this trani).
This cam is only $150. plus $100 for lifters Timing chain and gears are about $150.
I priced a roller cam and with the lifters it is $1300. No way I'm spending that

Took the pan off after work today. Had to jack up the engine to clear the crossmember but it came off no problem. Nasty contents but at least there were no surprises inside.


Starting to remove the lifters now. Got three of 16 out. Wow they are tight. A bit of varnish making it very difficult job. Taking a break for the evening while I drool over my new limited slip for the Bonne.



Got a new oil pump to install tomorrow too.

Hey, surprised I just managed to find this now...

Oh well, good to see another Firebird/Trans Am lover on here. My first car (which I sold 2 years ago to go to school ) was a 1979 Formula 6.6L (Olds) WS6. It was mildly tuned with an Edelbrock carb, intake, hooker headers, exhuast. Not a barn burner, but a good fun car.

Here'* a pic:

Keep it up with the updates on your 'bird!
