Great info. I could not find any cam specs on the 1990 360 cam. Leaving the original cam in will save me some time. I do know it would have really woken up the 318 I bought the cam for. That cam is damn near flat.

Thnx for the replies. I really just wanted to know if they were mechanically compatible. My understanding is that since the same block casting used roller and non-roller lifters I could. If were keeping the truck I would buy a roller cam not use the cam I bought to replace the broom handle...

Thnx for confirming what I was thinking.

I just picked up a 1990 360 to put in my 87 d150. I'm putting this motor in to sell the truck. I bought the summit 6900 cam to put into the 87 318 that I was going to freshen up but bought this 360 for cheap. From what I've read the 1990 360 motor it's pretty good for horsepower and torque...

I understand I will get it checked out by my machine shop. I will most likely replace it. If I gonna rebalance I may as well go with kb107s to bump up compression with the 974 heads. We will see when I decide to start on it. I picked up since it was a good deal and I figured the machined...

I appreciate all the info. I agree about the mixing pistons. Heck I've seen guys use 460 pistons in stroker mopars. I was less concerned about that fact that it was a ford piston I was more concerned about wanting to know what piston I had so I could find out the specs. It's more than just...

Thanks for the info dukeboy. I called Federal Mogul and they confirmed that they are an obsolete mopar 360 forged piston. They have -11cc dish. So they appear to be forged stock replacements. Mystery solved. With these pistons it looks like the 974 are gonna give me a low compression ratio...

I think I'm more confused, but hey if I have the piston valve clearance then I will go with it. I will check the piston depth. I have done this with flat tops but not a piston with the raised ring. Do I measure the out edge which is lower or the top of the ridge?

ok so I got a closer look at the bottom end. The rods are stock 360 rods. These pistons look like forged to me. The machined bottom and the lack of waffle pattern behind the wrist pin . what do you guys think?

Yep it was not done the way I have normally seen. This is going in my d150 once the 318 gives up the ghost or I get other projects done, whichever comes first. So it will be a low RPM application. I have rebuilt 974 heads that came with the motor but I've heard the small valve 302 heads off...

Thanks for helping me figure this out guys. I wish I could ask whoever built this motor. The guy I bought it from had no info since he got when his uncle passed. Who knows the real story. I'll take it to a machinist before I assemble it. It will be while but will update this thread when I...

So I had time to pull the pan really quick and check out the crank. Should I be concerned? Also the damper that cam with it was for a 318 which is internally balanced. Maybe it was a mistake? Or is it possible and / or probable that some one would internally balance a 360?

That makes sense. I guess I got confused because they look so much like these forged trw 360 pistons.

I'll dig in more once I get it out of the back of the truck. I need to drop the pan and check the rods. I did notice that it looked like a lot of balancing work was done to the crank. Can anyone confirm if these in fact to appear to be TRW forged pistons. I basing that on how the center...

so I picked up a rebuild 360 shortblock. The pistons look like trw forged pistons. But the part number matches up to a 351 Windsor, which also has a 4.00 bore. See the pic below. I'm really confused. Was this some old school trick? The pin sizes are different, compression height are...
