Lookin' good Dennis!

crazyhorse, i saw a post the other day about a rollmater double row timing cain for this application. you have to do a little grinding on the back side of the timing cover but other than that its a drop in upgrade. it's gotta be a stronger timing set up the a single row. wouldn;t you agree. ratman

In the event of a valvetrain failure, the screens prevent debris from making their way down into the rotating assembly area.

Dave at Wesco Engines has always had a good reason for using the parts he puts in his customers' engines. I don't have any doubt that there are other good parts available for those applications. I'll stick with the parts that Dave recommends.

I spoke with Dave before about the single row timing chain set. He said that in all the years he has been building marine engines that he has not had one timing chain failure yet. He had mentioned something to the effect that about after 500 hours on a marine engine he has always found them to look fine after disassembling an engine for a re-fresh.

I remember back in the 1980's we used to hear of guys who raced circle track cars that used what I remember as a Speed-Pro "truck" timing chain set with great success. I can't remember if they were a single or double row timing chain set, but my friends would still use them in their offshore boat engines----lots of hours, and no problems.

It's nice to be able to use decent, well built parts that you know will work well, but I have learned, and been told by a few builders over the years that when it comes to using "trick" engine parts, that sometimes there is no "trick".

The truck set was a double-row chain and sprocket setup and it was a vast improvement over the plastic-coated aluminum gear/single link chain setup used in passenger car engines.
The Cloyes Tru-Roller was the top-shelf setup that the big boys used but it was expensive back then, around $120.
Of course, the two cams everyone had to have were the "3/4 race" and "full race" cams,,,,Lunati, Crane, Cam Dynamics were the big names then.

Dave has the carbs apart and ready to rebuild. New gaskets etc and paint.

Blower pullies and belts are on.

What name valve covers are those??

Talked to Dave today, nice guy

Dave ordered them, I will have to ask.
