1. I just recently bought a 94. And it is said to have this and that but my question is from a stock 5.0 how much would need to be spent to get it to around 350-400 hp all motor.

It is said to have GT40 Heads
180 Thermostat
King Cobra Clutch
4:10 Gears
FLowmaster
H Pipe
Shorty Headers
Steeda Short Throw shifter
Cold Air Intake
MSD Ignition
30 over
Cobra Intake
And the top and bottom has been rebuilt.

But im curious what it would take from stock and around the price range.

Or would it be easier to swap engines?

so right now its a 306

youre you have the right bore for a 347 stroker kit

347 FTMFW

[Iownastang]

yes but how many miles does the 306 have on it/?

I would not build a 347 on a block that is not fresh.

So those are the mods that your car has right now and you would like to make 350 to 400 hp.

how much money do you have?

Is this just a street cruiser?

I would keep the cobra intake, but a set of trick flow twisted wedge heads, roller rockers, hit up a custom cam grinding company for a cam. I would also upgrade the Fuel pump to a 255 lph pump, put a 75 shot of nitrous on it. 24 or 30 lb injectors depends on it you want the nitrous or not, adjustable fuel pressure regulator, 70 mm tb, 70 mm egr spacer, and whatever other little goodies you might want but with the nitrous it would put you above 400 hp at the flywheel.

i agree with everything but the trick flow heads. personally id go afr 165s. or 185s if he wants to buy new pistons or have his current pistons milled

Why dont you like trick flow heads? They leave the 165's in the dust. And are closely compared to the 185's.

If you went with the 185's you would haft to notch you pistons b/c the stock valve reliefs are only cut to a 1.94 1.54 exhaust valve.

With the trick flow heads there is no need to notch your pistons.

Piston notching can be done very easily with a notching tool or a dremel tool if you have some big balls. It has been done by jbig on here but i would not recommend it if you dont know what you are doing or you dont want to screw up.

The engine is said to have around 20,000 miles on it. And as far as a street cruiser, I want to take it to the track every so often, and definately pull up beside others on the street and go at it. What I really want advice on is how much this adds to the HP for each part, well an estimate. Like i said im very uneducated when it comes to cars but the feel of speed gives me the happiness I need in my life. haha. I have put a picture of the engine on my pictures. But im not a rich boy but try to stay under 3-4000 unless it just requires that much more.

[83fox]

a few people at the local track had them on their 5.0 powered cars and the heads failed causing the motors to fail, whether it being the valve guides wearing out or the actual valves dropping into the combustion chamber

Everything could be had in that price range.

Its probably around 260-280 right now.

Like I said a good set of heads a few supporting mods and nitrous, you could have a 400+hp car for under 4000

Any head can do that, not saying they will or wont anything can happen.

If trick flow heads were junk their wouldnt be so many people out their in the world running them.

[Jezadiah]

I hope its wround that, I am hoping to get it dynoed in a couple weeks, that way I know where i stand on my goals. What type of heads would you prefer? Also the most gain for the cheepest buck as far as short term and money goes what would you recommend?

[83fox]

if you want to go FI a turbo kit is always a great solution too

Trick Flow tw heads

220-230 at the wheels more than likely.

i never said they was junk. i was just saying i prefer the afr heads over them just because of what i seen happen at our 1/8 mile track here. im sure its purley coincidence but still.

but what is the c/r of the motor and what type of pistons does it have in it? We probably know as much as that as he does seeing he did not build the motor and the guy he bought it from did not give him much information.

I know you did not say they were junk I was just making a statement.

We all prefer different things it natural.

[JBIGBOOTSY]

200 hp N20. it'll put you right there.

Trickflow have been around alot longer than AFR. AFR are growing rapidly in popularity because they simply work and make alot of torque. Trickflow did have some problems when they first came out. I personally will not buy another set of Trickflow heads cause I have had them let a valve go on my engine. I have seen other ppl have great luck with them but I wont buy them again. These heads have been debated again and again. But I personally would rather have AFR's from what I have seen them do for 2 of my friends cars.

[83fox]

i understand man, im set in my ways and im sure you are too

and for once i completly forgot about the c/r. i have a feeling there isnt dished pistons in that motor haha

[Iownastang]

Even if it was stock with the hyper pistons he would still be fine with 6-8lbs

More than likely they are flatops but that still dont help us with the c/r its probably somewhere btw 10 and 10.5.1
