Ahh, come on, it's been pretty warm this christmas (although I have got out the the garage- feeling bad that i've ignored her), you could have had this done and over before end of the year.Yea I figured...maybe I'll wait till Spring, kinda chilly in the ol garage now.
If I'm off from work next week I'll jump on it. I'd rather do it outside (more room) then in a small single bay garage. :crazyAhh, come on, it's been pretty warm this christmas (although I have got out the the garage- feeling bad that i've ignored her), you could have had this done and over before end of the year.
I did mine with a double rocker when I replaced the cam. The worst CAM i've ever seen, several lobes were gone - I can't believe the engine even operated.
Good luck in the Spring.
The sure and accurate way to check is to pull the water pump, harmonic balancer, timing chain cover, and look at the dots on the sprockets. They should be aligned facing each other at Top Dead center
If there's an easier way, I am not aware of it.
The "dots" facing each other is an aftermarket feature.
"... look at the dots on the sprockets. They should be aligned facing each other at Top Dead center..."
Nope - the factory crank and cam sprockets also have the "dots". When the sprockets are "dot-to-dot" (crank dot at 12 o'clock and cam dot at 6 o'clock), the convenient feature for alignment, the engine will be at #6 TDC on the compression stroke. Turn the crank one revolution, and both dots will be at 12 o'clock, and the engine will be at #1 TDC on the compression stroke.

Can I be sure a true double roller will fit under the OE timing cover?
Looking in the Summit website now for parts.
PS here's the real stupid part by me:eyerole ...few years back maybe 4-5 and 12,000 milws ago (I) pulled both heads, had them totally rebuilt, valves, guides, springs, even studs. New Cam and lifters. Comp roller rockers...new water pump and hoses.
BUT... I PUT THE OE CHAIN BACK IN...IT LOOKED LIKE NEW.
Now I have that uneasy feeling.
Whether at #6 or #1 TDC, the dots will not line up if the timing chain has jumped a tooth, and it will be noticable.Are you sure? When putting mine back together again, I believe the dot on each sprocket was at the top position (i.e., 12:00) for Top Dead Center, compression stroke. I'll have to check out my pics again, but I'm pretty certain.
Thanks for the feedback...I'll be into it tomorrow.I put a Cloyes double roller in my 82 with no fit problems.
My engine shop ordered all of my parts from Summit when they did my valves and bored my cylinders for me. The shipping time was fast. Everything was ready for me to pick up when the block and heads were finished.Thanks for the feedback...I'll be into it tomorrow.
Probably going with Summits true roller set...
I know someone makes them for Summit, maybe Comp?
That is a nifty way to do it for stock cam sprockets. I have always done it the hard way, apparently.
However, I believe that aftermarket cam/sprocket manufacturers state in their instructions to place dot-over-dot while the #1 cylinder is at top-dead-center. GerryLP:cool
