Hey...that looks like Moparfest showground! Nice Plymouth you got there...
Re: HPT, I thought about it, the Moparfest haul was a looonnnnggg drive back (or so it seemed, home is Windsor, ON), but might be worth it to maybe just catch a little bit???
Sorry, I of course meant 'per inch of bore size' given that folks can have varying bore sizes.
For me that ended up being 0.018" for top ring, and 0.020" for the second ring.
Don't get me wrong, I'm not passing any judgment, rather looking to learn about the considerations that folks who are building engines are taking into account.
I tossed Mahle piston & ring set into my stroker build. Their recommendation was 0.0045" for top and 0.005" for the 2nd.
This is...
Someone should grab the bumpers...i am guessing just light pitting, so easy to re-finish and a genuine 'gold find' for the mid-west folks where it's all been eaten away by good old O2.
I know it's a tight fit in there, but could you get at it with even a Dremel cut-off wheel just enough to cust through that blob? Heck, enough so that you could then put a little beating on it with a cold chisel to completely split it?
Reggie is, as always, spot on.
I will say this: for my liking I would prefer to use some nice thick washers to give that mating area a larger surface 'connection'. There is something about that thin little spacer in this installation that just doesn't put my mind at ease! lol
OK, so given your model year and I'm guessing a 4 bolt MC setup, check out this Cardone "bad boy", literally the equivalent setup to what I have in my Coupe, but a 4 bolt MC config (Vacuum Power Brake Booster - 54-73309)
uggghhhhh...I LIKE!!!
So here is the thing, when I re-did the brakes on my Coupe I installed Cardone 54-73370, but even than (which is a dual-chamber booster, 10.75" 9.0" diameter) I still have just a tiny amount of room between the booster body and the valve covers.
Therefore....while I dread...
