Pistons for a 360

[driveamerican]

 does anybody make a set with a 4.080 bore and 1.88 compression height? has anyone used dodge pistons they show 1.84 compression height 4.080 bore but a 0.984 pin size can the small end of the rod be made to fit safely? oh I guess I should tell you it is for a galaxie with a c6 stock and a 3.00 gear not a racer just a cruiser. also I am sorry I did search but didn't find anything about this hell i don't even know if i am posting in the right place so anyway thanks for reading.

Thanks for the info

361 FT pistons. With the stock 6.54 rod, it comes out to exactly 10.17, which is cool if your block is square at that height. Guys, what are the downsides of this piston? How do you figure compression with a dish like that? What is the lack of a valve relief going to do? Anybody here use this before?

[driveamerican]

That piston will actually protrude from the deck if you are anything but uncut won't it? so all of the questions you gave me lead me to ask if one of the people on this forum dosnt have a solution I am going to need a crank and set of rods witch is ok but it would be nice to use this stuff up especially when your giving the parts and labor away. If I did use pistons for a 390 I am afraid it would just be another dent in the fe reputation. Thank you much for your knowledge and your time

If you knew what the dish cc is you can use the link below to figure compression. Assuming your rods are exactly 6.54 your gasket would compensate for the .002 piston height. What the piston to head limits are for this particular warmed up running engine would be better answered by Jay or anyone who has actually built one that close.

Surprised no one has experience with a 360. The catalog pistons I ordered in 1991 did come out of the hole but disappeared with the head gasket. I beat on it till spring when it broke a rod. $650 worth of pistons wasted. I was young when I sunk that boat and didn't pay attention to the particulars. If your going to beat on it I can say for sure buy new rods or find a set of 352 360 HP rods that don't snap the top off.

Head gaskets are available in many many thickness .

[chris401]

Yes, you are correct. He would be helped more by knowing the minimum head to piston tolerances. That would help him select the correct gaskets.

Of you need a crank get a 390 crank and
Use 390 Pistons since a 360 is just a
Destroked 390 with 390 Pistons that give
It to big squish height

OK, here's my rant. Everybody's solution is always the easy way out. Where the heck is the challenge? Doesn't it bother anyone that 350 Chevy trucks get the glory while 360 Fords are dogs? Can't we for once put down the status quo 445 with alloy heads and an RPM intake and do something out of the ordinary?

I had hope that Brent's 352 was going to be a good street/strip build. Instead it got to overly tecchy (rhymes with yecchy) and, as far as I know, is dead in the water. Damn, I wish there was a Grassroots subforum in here. Billions of short stroke FE's out there and nobody cares.

Somebody pick up the ball here and analyze this piston for street/strip use.

Looks like myself and the original poster are destined to become outlanders. I didn't get a PM from Jay begging me to admin a Grassroots forum for those DIY guys who want to tweak with factory parts, as well as refurbing all other parts on the car. Maybe he lost my email. Maybe he's just disgusted that I continue to hip check the Stepford-esque formula. Difficult to say.

Sorry, I'm still processing "350 Chevy truck" and "glory" in the same sentence.  What???  The words "turd" and "load" come to mind.  Doesn't seem like much of a competition. 

[chris401]

What is the acceptable clearance when building any engine out of the hole? I am not talking dome but the top outer edges. With .002 out and .021 steel shims seems plenty. Is there a buffer for rod and piston stretch when one is hot and running?

Gee, LOTS more people over the years have built up 360's than 350's. {guffaws} Have you noticed that there are old 350 trucks running in Stock Eliminator? Even a couple Dodges. Know how many old FE trucks there? Zee Row. You're right; not much of a competition.
