Early 71 340 - Cam Trust Plate

[Yellow71Cuda]

I just want to be sure, as I've seen many different pics online (and it's been years since I disassembled my 340).  Which way does the plate get installed?  It appears to have been with the "SP" toward the inside, based on the residual bolt marks.  My setup has four bolts, no oil tab, and I assume the bolt with the hole in it goes in the upper left.

Thanks!

It has been 25 years since I worked on a 340 but if all the holes line up either way and there are no special machine surface on either side then I would would say it doesn't matter. I could be wrong ?

SP toward the block.. The "witness mark" of the bolt head is clearly visible so it should be apparent...

Thank you!

Chrysler now makes a tensioner that fits under the stock timing cover and that prevents the classic "swish" that roller chain 340's were known for. Tightens up the timing a wee bit, too. I'd get the drip tab if not. Just my

Any other opinions on using this tensioner vs. stock setup?

I'll let others weigh in on their opinions, but Chrysler came up with this on their own to cure a known issue. It doesn't do anything except keep tension on the roller timing chain. We put one in my sons' 239 V6 and there's one going in my (God I hope I live so long) stroker 360.

The tensioner definitely seems like a good idea, other manufacturers have used similar parts with good results, the only issue I've seen is allot of aftermarket ones fail prematurely... And I've seen photos of the Mopar ones failing but I don't know if the ones that failed are OE or aftermarket....
