5.0 HO vs. 5.0 NON HO motor

hey all so im in the process of building my car up to do a little bit (well actually quiet a lot of) AutoX/road racing and I am in the process of getting ready to set the motor now the motor that I will be putting in to just get the car moving is that out of 1988 Lincoln Town Car which is the NON HO 5.0l motor now many questions follow such as
are there different pistons in these two motors
what are basic differences
and are there any pros an cons to one over another
the HO motor is 9.1:1 i believe while the NON HO is 8.9:1
or if anyone has any other info about these motors that they think could be useful to me please go ahead and post up
thanks in advance
Shelby.

I don't know a lot about these motors, but I can share some knowledge. If you didnt already know, HO means High Output. The higher compression engine 9 times out of 10 is the better to have. Your best bet for an autox car would have the matching year engine dropped into her, that way you know it will bolt right in. Second, the modular 4.6 4v engine would be a much better platform. It's a dohc engine with an an aluminum block so its lighter/better for corner cutting.

Well the pushrod 5.0 is lighter than the 4.6 by around 50lbs.

The H.O. Is a roller motor with a different firing order than the non H.O. Also the heads lift and intake play a part in the Hp difference as well.

The HO motors just have the 351 firing order. If its from a 88 Lincoln it should be a roller block. As far as getting a motor from the same year vehicle to make sure it'll drop right in.....ANY 302 will bolt right it. The year does not matter.

HO = 5.8 firing order. Compression on the engine has more to do with the year of production as the same pistons were not used in all stock 302's.

ProjectTurbov6. The 4.6 4v motor even though it is aluminum is heavyier than the iron block 5.0 motor even with iron heads. The 4v is not even close to being lighter than the 5.0 OHV engine as even the aluminum 2v motors are heavier.

Furthermore the Windsor OHV engines are a better corner caver mustang option than the Modular engine. Take a look at american iron for instance, the most competitive racers are running Windsors.

Well I plan on running gt40 heads so wouldn't that mean I could use a stock 5.0 cam which would also be the stock firing order or no?

What firing order your engine will have depends on which stock 5.0 cam you speak of. Either cam you use both will work fine with GT40 heads. Note that the HO cam with the 5.8 firing order is a little better at making power.

The cam does not dictate the firing order. With any cam you use other than the explorer cam will require you to upgrade the springs. Gt40 or gt40p heads have springs that are inadequate for performance cams

Yes a cam does dictate firing order. If you put an HO cam in a non HO block you must use the HO firing order for it to run.

The cam opens the valves, change the cam to a different firing order and they open on a different stroke meaning you have to change the firing order. You can pretty much make an engine have any firing order you choose ( obviously with certain limitations), look up custom firing order cams. Apparently you need to go to a real class....

Yes they'll work fine with the stock cam. I would look at the b303, e303, trickflow stage 1, or steeda #18 if your looking for decent mild lift cams. Prepare to put better valve springs on those heads if you do put an aftermarket can in.

3stangs: The cam and change in firing order is indeed what makes the 5.0 "High Output." Anyone whose been around a 5.0 HO motor for 30 seconds knows that.
