Ok now I know I have read this post before on here, but I forget where. What I want to know is what do i have to do to my 5.0 to make sure it want blow up anytime soon. It's in great condition now and I want to keep it that way. What parts will help make it withstand the increase in horsepower as I add new parts and and what HP ranges do I have to make the next leap in stronger parts?

any info is appreciated!!!

What increase in hp do you have? There are lots of factors that cause engine failure so it varies from car to car and from person to person.

well right now i just have

cobra intake
full exhaust
f cam

everything else is stock

but im looking to:
jump to about 300-350hp by the means of supercharger and all the other needed parts.

what I want to know is as far as pistons, engine block, heads, crank and all the other parts of the lower engine block, will they hold up?

also i have a newly rebuilt manual out of a 94 stang.

keep the timing right. If you hear any knocking or pinging, make sure the timing isnt out of normal or too high. When you are dealing with power adders, you might want to get forged internals. You can run stock internals with low levels of boost. As with any safe way of handling power adders, get a good PROFESSIONAL tune.

forged. as in forged pistons? and is there any other specific parts i can swap out? Lastly is there any warning signals I can look for to see my enigne isnt capable of handleing the power?

[Stangzilla]

A 1987 already has forged pistons just make sure you have a good tune and you will be more than good to go at 300-350hp

[Stangzilla]

Well it might be a good idea to have a compression test and a leak down test done to make sure your engine compression is still within spec and your heads are still keeping in that compression when the valves are closed. When you install a supercharger your manifold, head and cylinder pressures rise greatly and if your motor is not able to contain those increased pressures well I dont think I have to tell you what could happen!!!

Would just forged pistons be enough, or would he need a forged crank and rods, the whole assembly forged?

[Stangzilla]

No a forged crank is not needed unless you plan on making over 600hp. Forged rods are a good idea but for under 400 hp he should be ok as long as his current motor is up to snuff..

A stock 5 liter rotating assembly (with either forged or hyperutectic 1993 pistons) will outlast the block.

This is good to know. I'm about to crank up the amount of power, just b/c I feel the need. Not many fast cars around here. (None of them really test me)

I am still learning guys! But thanks for clearing that up.

[TT86]

If i were you, I wouldn't worry about the internals of your motor until you get past the 400+ hp range. And even so, when you get up there over 400, as long as you are running a moderate tune, the bottom end will be ok. To put things in perspective, I am running a stock bottom end on my TT 86, which is producing a little over 500 with a very safe tune

[Tony_90fox]

I have been lied to my entire mustang modding career then. I am glad you boys cleared this up for me.

a stock block can handle up to about 400 hp with out it cracking down the middle

[GTXRacing]

I thought the stock blocks could last up to 500hp hmm. Well just a quicky question. Does the 88 GT stangs have the forged pissins?

I know plenty of people running 500hp on a stock block 5.0

500hp at a reasonable RPM is common. I know people that are making in excess of 550hp at the wheels with stock short blocks.


87-92 has forged pistons.

wow this info really opens up a lot more doors, and will def. make me worry a lot less when I drive the car from now on.

Since im getting good responses' on this post I got another question.

Im getting the Jacobs FC 5.0 ignition kit for the price of $399.99. I have heard a lot of good things about it and it is in my price range. What are some of your guys opinions about this purchase, and what can i expect to see from the mod?

Thanks again guys!!!
