Identify Roller Motor

[Lester]

Can anyone help me identify the roller cam H.O. 302 from a non H.O.

Of course the heads H.O's using the roller rockers, I think the Intake manifold is a little bigger along with the throttle body and injectors and a 351 firing order. I'm sure there's more info but I'm all out lol...

I am trying to find a used motor and I just don't want to get taken.

Do you have a motor in mind? If not I'd look for a Lincoln mark 7 LSC those had the 225hp H.O's stock.

I was thinking of a 1987-2003 mustang motor,what year is the mark 7 motor your talking about

I cant find the Thanks button but thanks for replying

I had a 87 with the H.O. If you check the firing order to make sure it's a 351 order you should be fine. 1-3-7-2-6-5-4-8
