BUILD THREAD 1987 Olds 442 Project Build

[oldsofb]

Got the Oil Pump mounted to check the screen height. All good by Moroso specs. Their tech line guy says it designed for 1/4 - 1/2 inch clearance. You also have to measure both sides and take an average because of the tilt of the screen. I got an average of 5/16.

With that checked, I moved on to the Camshaft. It's a Howards Cams Hydraulic Roller 4/7 swap. 0.560/0.555 Lift 224/228 Duration @.050

I use the front Oil Galley Plugs from the 307 (since they were longer to fit the Thrust Plate.

I used this custom Thrust Plate made by Clark455 over at ClassicOldsmobile.com. He used a bronze bearing material.

Install the Double Roller Timing Chain and put the spring and Cam Button on (also from the 307)

All for now. Happy Memorial Day!! Remember and Thank those who served!!

I put 1 and 2 piston in to check TDC and check for the correct Intake Centerline on the camshaft. The piston rings are not file to fit, but I still match every ring set up with a specific cylinder and bag them for installation.

I use the piston stop method to find true TDC.

Back the piston off of what is the assumed TDC and install the stop. Run the piston up to the stop and then rotate the degree wheel to 0 TDC and lock it down. Rotate backwards until it hits the stop again and observe the number. Take that number and divide by 2. Rotate the degree wheel to that new number and lock it down. Check your work by rotating the crank back until the piston hits the stop and it should be the same number on the other side of TDC.

With that I checked to make sure the timing chain marks are the same as when installed.

I use a lifter bore dial indicator in the Intake Lifter bore to check the cam.

I rotate until I get the highest reading (top of lobe) and "0" the dial. I rotate counter clockwise about .060 and then clockwise until I'm .020 off of 0 (this is to eliminate any chain slack in the reading). I record that number. I then rotate clockwise to 0 and then keep going until I'm back at .020 and record that number. Take the 2 numbers and divide by 2 and you have the Intake Centerline of the cam. Mine is 106.

All for now.

See I wish I knew how to do that stuff. I think cam timing is my problem in my Cutlass

I literally watched three different vids on youtube over and over again until it sunk in. 🤔

Hutch the video on your channel was outstanding, tons of info. once again great to watch your progress and learn at the same time. I even went and got a cold beer and relaxed in the lazy boy to enjoy it.
