Boost and Stock 302 block ?

Just wondering how much Boost will a 94-95 Gt with a stock block is going to be able take ?>
The car has the basic bolt-ons and some rocker arms with a full DFI set-up for tunning,.
I will be putting a T-76 Garret turbo in there sometime soon .

There is no certain level of boost that will break the block. Just push it until it does. If you don’t plan to run a lot of boost through that T76 you will make more power with a smaller turbo by keeping it in its efficiency range.

I was told with the DFI I can safely turn roughly 15-20 pounds?
MY upper Intake is stock but has been por matched to match the lower for the best flow ...
So you dont think that the bloch will blow ?

No tune, or program (DFI, PMS, FAST) will hold that block together. You could run 15-20 psi on a stock block, but the question is for how long, and you will be on borrowed time. I would not push a stock block past 500 rwhp.

Try not to think of it in terms of boost pressure, it's just a reading.

When you start reaching 450rwhp+, things are going to break. Keep the rpms and detonation in check and it should last for a while, but at the same time, you'd better save up for a decent block (SVO, Dart, B50).

That makes alot sense.
I know in time I will have to get a new block , maybe one with stronger rods,pistons etc.Hopefully this will last me at least 6 months untill I can do the math on how much money I really wanna spend on this car ..


Mustang greg,
The SVO block is good for how much pressure or actuall hp it can take ...?
BTW my I just figured LS1.com name is not welcome here ..LOL

To answer your question, you probably couldn't make enough power to break that block as long as all machine work, parts, tune is correct.

Pro 5.0 and SSO guys make 2,000hp using them.

I thought the same thing goin' over to LS1.com.

I'm an enthusiast, with a little ford bias , so it wouldn't bother me at all.

BOOST!! Means nothing

Horsepower means everything!!


When you get up to 450-500RWHP Things are getting pretty scary it will go there just not very often before splitting in half.

whats boost? Oh you mean that thing that tells you how restrictive your intake is?

If you are going to do a large turbo install do yourself a favor and get a R302 or similar block. Get the bottom end buttoned up FIRST so you can still sell or do somthing with your stock 5.0L block.

A split block is worth nothing, a running 5.0L engine is worth a few hundred bucks.

Good point but What does the R302 have that I cant do to the block thats in my 5.0 right now ???
Your point makes alot of sense but Iam on a tight budget right now , thats why the new block hasent been bought yet and I am hoping that this block will hold up for a little while ...

It has 4 bolt mains and weighs about 40 extra pounds (160) which strengthens the main webbing and the lifter valley. It also has Siamese cylinder design. It can be bored/stroked to produce 360 cu. in. Just compare a 2 bolt main cap to a 4 bolt main cap and you will see why. Here are some pics of my Dart block:

01 ls1,

I know the horsepower bug is biting at you right now, but your best bet would be to hold off and get a quality block with quality parts.

Putting good parts in a stock block with a turbo behind isn't going to be pretty, and you might just lose the entire reciprocating assembly when it goes boom.

Do it once. Do it right.

Or you could just be building a real motor while running the stock shortblock....may be surprised how long it holds together. once it goes then put the real motor in the car with the good block and internals

well, so far I'm just under a year (10 months) and at 530rwhp on pump gas and still kicking so we'll see how long i can keep it going...only difference is I don't have another motor to put in it when this one breaks
i'll face that problem when the time comes
