I need to borrowyalls knowledge for a minute if you dont mind. I just bought a motor out of an 86 mustang. It was originally in a bronce they saidbut they then put it in the stang. but it does have the mustang intake on it. It is not an HO i am guessing due to the firing order. So my questions are what is the difference between my HO engine in my stang and this motor and what all can I do to it performance wise because I heard I can't even change the cam due to the pistons. True? I would really appreciate it!

What's a Bronce?

i dont think the pistons were any diff in the ho's rather than the non ho's.

I think he means bronco??[&:][&:]

it may not have a roller cam either but best way to see what you got is open it up ftw!!!

Ya i mean bronco. So the pistons are the same and I can just put a different cam And valve clearence should be good? or should I just tear into it?

im pretty sure the pistons are the same so all you have to do is swap the cam out and it will make it a h.o. this might be a great time to rip her down and rebuild her nice

YA I might do that. But why is there always confusion when it comes to the 86 engines and some say flat tops and some don't... Also do you guys know anything about those BBK intakes i think ther the SI or somthing. they come with the fuel rails and TB. Good or no good?

You said something about the firing order. What is it exactly. You will find out what you want to know about the pistons when you pull the heads off anyway. You have to remember that the pre82 302's have a different firing order.

just pull it apart so you know what you got
