No disrespect intended but it sounds like you want someone else to do your google searching for you.

"I need to get all the specs below of a stock 302 motor...."

That is like asking...

"I need the dimensions of a Nike Shoe...."

The size of a Nike shoe depends on the shoe size, and the design of the shoe.

The Ford 302 is the most popular Ford motor ever produced. It rivals the Chevrolet 350 as the most produced engine ever. They have been produced for 30 years and have many different options.

For example; an 87 Ford LTD with a 302 will have different specifications than an 87 Ford Mustang with a 302. Not only are they different from car to car, but from year to year. An 87 LTD may have a different CAM than an 89 LTD with the same engine package. A different cam will change the specs.

We need to know the exact year, and model of the vehicle you are talking about. If not that, we need he engine code; something to differentiate it from the hundreds of thousands of 302 motors that have been produced.

It would also help to know what year motor it is like stated above, for example comp. ratio was any where from 8.3:1, 8.4:1, 9.2:1 & 9.0:1. most of the HO cam specs are the same running .278 lift intake & exhaust with a 276 duration intake & 266 exhaust. The GT40 motor had a .282 lift intake/exhaust with a 270 duration intake/exhaust. more info needed....

Jeez... Ease up, guys. It seemed like a legitimate question to me, I assume he's asking for a typical 87-93 HO motor, which changed very little anyway.

Except for

RPM (Min):

... What does that even mean? Min RPM=0

To the OP- If someone hasn't done it by then, I'll get back on tonight and read the exact values from one of my books.

Until then, off the top of my head-

87-93 HO 302:

Compression ratio: 9.0:1
RPM (Max): Computer limited to 6250 (IIRC)
Cam Type: Hydraulic Roller

Ok, guys...yeah I need the above specs for a 1992 bone stock 302 motor (from an LX 5.0 hatch). I was pretty sure this particular sub-forum was intended for Fox body 5.0 302. Sorry for not being more specific but...that's what I need...I tried googling but wasn't really able to find this info.

Thanks again!

NikwoaC, thanks a bunch for those specs...much appreciated. Yeah, I'm not sure what they mean by the min rpm...I guess maybe they mean idle rpm.

I am getting this info because I am having a new carb built and they want these specific specs
