Coyote shortblock build

[Mystickeith50]

Lol yeah I was aware of possible piston issues and sure didn't want to go back with stockers. Turning up the boost probably didn't help things. From
the looks of it I'm glad the pistons didn't completely blow and hurt the heads. It actually still ran ok. It just idled a little rough and smoked bad. Goal is now a solid 650rwhp pump gas daily driver or more if I can get it.

What did u up the boost to before it blew.

I still run 5w20

Should've been 10+ lbs of boost. Never got the boost gauge working right. I went from 3.75 stock pulley to 3" pulley. Also did BAP, Edelbrock CAI, colder plugs, and tune. Was an animal and can't wait to get it back going.

For what's it's worth I can get mobil one 5-50 syn at walmart for 27 bucks for 5 quarts.

Damn I'll check into that. Always liked their oil and that's a lot cheaper than through Ford.

Good to know. Did you install the piston squirters? I left them out.

 

[Twinscrewgt]

I kept them.

 

[Nastystang06]

I kept mine too

Just assembled my Boss short block last night..

Working on a write-up. I have all of the part numbers and everything - however the 2011-2012 block is no longer available, as they are replacing it with the no-squirter block

No machining required. I did use a bore gauge though, to move the pistons around an average out the clearance. You don't want to put the smallest piston in the biggest hole.

FYI - the production Boss oil pan is cheap and it has better baffles.
It's the 302R pan from the race car that's insanely priced.

doesnt that pan hold like 12 qts or something or is that the 302r pan?

I went with the production pan, call me cheap

$1300 oil pan! Wow and no thanks. I think my stock coyote oil pan is just fine.

 

[bestmustangparts]

Well the $139 one isn't out of reach and it's an improvement.

That's not being cheap man, that's called being smart. Put that $1000 towards something else.

Not sure it would be worth it to me, but yes that's not too bad of a price. I did upgrade the oil pump gears to billet units and the valve springs to the Boss units. I just didn't see the need for the oil pan myself. I'll be drag racing the car more than anything and just a daily driver. No other types of racing for me.

 

[Nastystang06]

So did you keep the squirters?
Im thinking about eliminating mine now lol.

 

[VET-KLR]

I bought the Boss shortblock complete with the blockoff plates. I left it alone and don't plan on putting them in.

 

[Nastystang06]

Yea I almost see no point lol

 

[VET-KLR]

Maybe if I was autocrossing or road racing. Something holding higher RPM for extended times I could see the value. I'd rather have less windage and gain a few HP up high. Plus they just make me nervous. Not sure what happens if you get some clogged and only a few pistons are being cooled or hit with the oil. Plus they don't run them in the Boss motors or the new motors.

It's alive! Got it running today. I've put about 20 miles on it and runs great. That is not something I hope to do again anytime soon. What a PIA these cars are to work on.
