That might be a bit much for stock head gaskets and a stock lower end..you could give it a try...if I were you I would stay around 10lbs and see if the motor handles it...if you dont care about blowing a head gasket or hurting the lower end then go for it.....

My old notch I ran 8-9lbs on the stock motor and the head gaskets were hurting after about 5k miles...

Ok well Im definitly gonna take adder's advice and get some cometic headgaskets, doing some of my own research they seem really amazing, as far as 13# of boost being too much for the bottom end hmmmm, Idk r.barn says it seems ok, but maybe a little more input from anyone else would be great, and NO im not saying that you guys dont know what your talking about I just want to be sure before I do it haha. And as far as turbo hmm could be a possibility I never really thought about it tho, always assumed the price tag was much higher, although ill do some research and look into them more now.

it was either MM&FF or 5.0 that did an article about 3 years ago about crazy boosting a stock 5.0... they ended up putting right around 14psi on a stock block, and after blowing head gaskets twice in a day, they got this kit to carve o-ring grooves in the head and block and put oring gaskets on and didnt have an issue with it after that. It made almost 500hp on an otherwise all stock block, just a big a$$ turbo on it. It was an article about making a 10 sec car for under 10k, and they did it with cash to spare.

Why 13 pounds?
Whats with the weird number?
Why not aim for something easier.
Lets say...8.
Then if your not satisfied, bump it up.
You have NO BOOST at all right now, why jump the gun all the way to 13?

r.barn

I've seen tons of people post up running 15 lbs of boost on
stock bottom ends for years with out problems.

You're definitely pushing things, but as long your not out
there doing 3-4k launches and 6,500rpm shifts everyday it should last fine.


Trust me for what you are going to spend on a Procharger kit
you can get a nice turbo kit for same and make 10-20% more hp for same boost.
Turbos are back!!!!!

Honestly r.barn, I just talked to the guy from quick time turbo, and they seem nice as hell, top quality kits too, and thats actually what im gonna go for, Not to mention it will be a little more unique than a procharger. Thanks for the heads up

BEWARE of the Cometic Head Gaskets.....I had to retorque the heads twice becaues my Cometics were seeping oil and coolant!!!!!!

Even now they still seep a slight bit of coolant, but not enough to worry about....even Cometic will tell you this occurs often....Good news is they are supposed to be able to handle boost well...I am stuffing 11 pounds in mine now with Methanol and so far so good.....

I would look at the Fel Pro MLS Gaskets..supposed to be as good as Cometic, but seal easier...(Do an internet search of Cometic leaking or seeping head gaskets and you will see what I mean)

Go to corral .net (without the spaces), go into the forums and type in "cometic problems" into the search box. You'll see what I mean about very clean and straight surfaces and the problems associated with them. They are GREAT headgaskets though if you spend the money to do it right.
