Timing Chain

Hi Everyone,
I'm getting ready to build a non-roller 383. Does anyone knows if my L98 timing cover and Cloyes True Double-Roller timing chain will fit ok on the 383?

Thanks!

The cover will fit, but the chain won't.

Re: Timing Chain

You can get it to fit fairly easily with minor grinding.

Re: Timing Chain

Will the chain itself not fit or will the holes not line up correctly?

What do you have to grind?

Thanks again!

Re: Timing Chain

The chain may not fit.

It may rub on various of the little bolt bosses. They are often larger than in earlier blocks; the edge of the chain rubs on them.

It's really not a big deal, people do it all the time.

Re: Timing Chain

I was thinking that the L98 roller cam timing sprocket wouldn't fit a non roller cam, but I suppose you could get a non roller cam with the right nose on it.

Re: Timing Chain

Well yeah, there is that; a roller timing set won't fit a non-roller cam.

Kind of hard to tell what we're mixing and matching here.
