Olds 358 build

[olds307 and 403]

Well the cam and lifters arrived. In a white box with Edelbrock on the outside, Olds Performer 350-403. I opened it up, Torco assembly lube, Edelbrock lifters and the cam suprised me. Under the Edelbrock part number sticker are the correct cam specs. I will try get it back apart, install the cam and lifters. Degreeing may be the next couple of weekends. If I can get the cam and rings broke in before the weather turns, it will be a big bonus. Then I can get in the garage for the Winter EFI install.

I got it installed in the motor, dot to dot on the timing set. I used Comp's lube on the the cam, Risoline ZDDP 5000 ppm additive in the feed holes and sides, Torco lube on the lifter bottoms. I'm going to pull the heads and put the degree wheel on it.

One thing I noticed was wetness on the Canton oil pan drain plug. It was tight. No amount of oil in the pan, just assembly lube.

. I pulled the heads, I know this timing set is accurate, already checked it. Now to remember how to degree a cam, Comp includes instructions gor degreeing. Here are the cards and my set up.

The intake centerline with it dot to dot is 105, according to Comp's method, 106 is the spec.

Its perfect. Leave it alone!!!

 

[olds307 and 403]

Yeah, it is. I'm not sure if I should even bother with checking the rest of the cam timing events.

Honestly if it’s that close to dead on I wouldn’t bother. Like I did the last custom cam I bought for my race 565 I did check. But that was because if I remember it was say a 108 Icl cam and when I degreed it I got 104. And I checked it through every technique I could. Even had the comp cams book out going step by step. Changed the timing chain and no difference. So I had to retard it 4 degrees to get there. Now I’m wondering how this custom cam could be that far off? Did I even get the right one? So I started measuring everything else and degreeing it to other cylinders to make sure it all still matched. It did come up right other than not liking being straight up with the timing chain. It wound up making 980 hp at 7200 and 800 ftlbs of torque at 5600.

Motor together in the car, on the mounts. I just need to install the intake. I just stuck the Performer on loosely, didn't want to risk damaging the RPM SEFI rails. Snow on Monday, just in time. Will get the intake on, the Lucas 30W break in oil in the pan and primed with a drill and get it ready to fire and break in the cam.

Just in time for snow? Canada is a dick.
