Man...Did the lobes of my cam go flat


What I thought was a lumpy cam in my goat, turned out to be a cam that ground itself down. Some farmer that likes Fords put this car together. I got rid of the ford wiper washer bottle,Ford speakers,rubber from a converyer belt to hold the rad in and now 1/2 of the blue Ford paint on the engine. Here's a few pic's of putting in a new Comp cam and making it look like a Pontiac again.

Looking better and will likely sound much better too!

Changing a Pontiac cam sure isn't the simple thing like changing a cam on a small block Chev, is it?

I love that Pontiac blue. 
 When a new cam is installed there is a break in procedure that some people neglect to do. Result: cam lobes wear off.

you must use the proper oil(with zinc) or EOS also.

Did you check the screen for the oil pump pick up.Wiped cam lobe could mean metal floating around.Use lots of zinc.

I thought the cam went flat,because the car sat for so long and being dry the lifters just caught the cam lobes and that's all she wrote.

I never thought of adding Zinc. Thanks guys for the advice and maybe saving a new cam. I oiled the cam instead of putting that cam lube on it and did an oil change and put a sleeve on the balancer, but never thought about checking the oil pump screenweirdface

Carl 1 you Chevy engine guys have it easy and alot cheaper on parts and gaskets too.

I've only built one US Pontiac engine in my life (455) and I sold the car (64 GTO convert clone) running but not finished. So far, it runs fine but the car has not been totally restored yet so hasn't hit the road.

It was very foreign building an engine that had #2 cylinder as the front journal on the crank, a bolt on fuel pump eccentric, and that whole front timing cover etc was SO unusual to me.

Here is a link to Pontiac engine colours over the years. COLOURS Our 70 Tempest was close to the new colour in this thread but our 76 Frebird was a blue not that far from the original picture in this thread.

I have e-mailed Horst many times with green Pontiac small blocks 55-57 as well as the green and aqua 261 but he has not updated the page. In my opinion it is incorrect for Canadian cars since the tri 5 years had the dark geen small block. 1958 was the first year for the orange paint I believe.

biggrin No worries, I'm in therapy and soon will likely be able to spell Ch**y with only one star in it instead of two if I continue to progress as well as I am. Heck, I used to spell it like this  C***y so it's already better!

Dave's a great counsellor!
