In the pics posted they all appear natural, that or the paint has flaked off over the years. My former chall 340 they were missing so I guessed when I did it and painted them. I know big blocks were in fact engine color . and I know later years small blocks are engine color

I don't have a newer parts book here at the house to say for sure about 72 and newer. But I've seen some newer 360's with what appears to be the exact same bracket on it

Speaking on painted parts, I have yet to see an original dip stick painted engine color, so far all have been black and the tube engine color. The rubber valve cover grommets, PCV valve, and oil fill cap have all been engine color. I'm speaking on 71 engines painted orange, there may have been variations with different era small blocks.

One thing is for sure, no one is 100% on 340's Maybe i can get a hold of Rhinodart to see if Bill's car is in chicagoland area, and spend an hour taking pic's and verifying bolt , kickdown, brackets, ect...

There are still some minor details that get debated, just as on other Mopar engines. *Bills Demon (and Jim Rhineheart) are in Scotsdale AZ right now, just spoke with him today

And you have the 340 six packs that are an animal in thier own. Because of TA/AAR values those engines are more researched out. And didn't the the 340 TQ's in 71 have a recall or some issue? And most were swapped to a 72 TQ. Making a survivor with the OE carb even harder to find. When someone back in the day does a carb swap stuff gets disturbed at the same time. That's got to make it tough to find 71 info. Is they why the orange Demon has it's carb switched?

The Demon had some kind of problem back in the day, small carb fire or something, as a result it is also wearing some touch up engine paint on the intake and drivers VC

Looks nice to me Just having the original carb and what looks to be the original master cyl puts you way ahead of the game !!
