I have friend that has a 1400 flywheel hp mustang. It is a 345in motor. Before the boost from the blower he made over 520hp to the wheels. Granted he has a $10,000 Motech computer and has spent over $85,000 in the motor but that is very nice N/A hp. <hr></blockquote>

85,000!!!! <img src="gr_eek2.gif" border="0"> <img src="gr_eek2.gif" border="0"> <img src="gr_eek2.gif" border="0"> pro5.0 motor??

Yes it is. He made 520+ hp before he decided to build the big motor. He is racing in the street outlaw class with 10in. tires. we built a nice set of headers and a 4" x-pipe for it. They wont last long...... his car is gardrail bate.

Bottomline, most 5.0 guys are not thinkers, they are followers, who still count their wins over 305 IROCS from racing in the 80's. Well the 80's are over and so are the days of Mustang street supremacy, LONG LIVE LS1! <img src="gr_grin.gif" border="0">

Wow, I was searching for something else and came across this thread from 2002. There are some truly uninformed people who have no clue about the 5.0

in 2002, I ran a 302 with a stock bottom end, unported gt40P heads, an unported edelbrock intake with a 500 lift cam and it put out 425hp to the tires. I ran 11.50's at 3200lbs and I drove the car everyday.
It was an Explorer engine that I changed the cam and intakeand rockers and that was it. Everything else was from the factory

Before I get flamed, keep in mind, I am putting an LS2 in my Mustang.

I couldn't care less if it's a sbf or sbc, as long as I am racing again.

Doesn't weigh less than a Corvette... When I was in the Marines and my car was stock I routinely put a hurting on my buddy with a H/C mustang. After the 60' foot mark it was a foot race and a mustang will not do well in a foot race against a C5 corvette with similar mods anyways.

the 302 CI engine is an old platform, but a low ten second car can be had for not much based on it, but really it's been done so much it's kind of boring at this point. IMO.

so you follow that with . . .

come on man, I know this is ls1tech so you have a pretty good chance of everyone's knowledge based on hearsay but seriously.

Even today's factory stock classes don't run that fast and you claim to have little more than what that class runs.

Your combo maybe maybe did 425 at the flywheel and even that would be with some serious "tweaking" of what is hidden under cast iron.

425 on a stock short block.....maybe on a 150 shot...lol...ive owned too many 5 liters to even think of believing that BS......maybe 325 with a very strong combo

haha i just looked at his combo.....looks like a sub 300rwhp setup to me....my bro inlaws 95 cobra gt40 heads cobra intake b 303 cam and all the supporting bolt ons only made 254 motor and 390 on a wet 150 shot....my buddies tfs headed cars one made 265 and the other with a lil more compression made 275.......all dynojet #s...

same here....I came from the other side.
Was there for about 12 years.

I'd bet his listed combo made 260-280rwhp at the very most. The milestone in naturally aspirated 5.0's has always been 300rwhp. Much more than that and the car slowly but surely becomes a dragstrip only car that is pretty ignorant on the street regardless of who tunes it. NA 425rwhp comes with ported aluminum heads, big custom cams, high rpm intakes, 331 or higher cubic inches. OR....tons of HIGH DOLLAR Factory Stock tricks and parts, but even they weren't running 11.50's in 2002...

425rwhp with what you listed above???

Qwiknotch

Believe all you want, guys...

I ran Pure Street in the NMRA back in 2000, not 2002 and we could not port anything, if you had a carb. and at 3200lbs, it ran 11.50@116 with a 1.35 60ft on 26/10 slicks.

you do the math....


I can reproduce that combination, if you like...

here is exactly what it is...

1989 factory block, factory rods with arp rod bolts and pistons
gt40P heads unported with a valve job and custom valve springs (factory valves were backcut)
custom grind hydraulic roller cam with .499 lift
unported edelbrock performer rpm "air gap" manifold
Holley 650 carb reworked by The Carb Shop
1 inch tapered spacer.
1 5/8 headers, 2.5 inch exhaust
I will give you this... it did have a race set of bearings and a custom ring gap.
this power was to the tires through a McLoed clutch in a t5, 26/10 slicks and 488 gears.
I shifted this engine at 7400rpm

oh dam!
there it is!
had to be the the top secret ring gap and the race bearings
j/k

that's pretty sad because I had my Saleen dynoed at Granatelli's last year for the dyno day with www.socal-racing.com and it made 260hp to the wheels with a completely stock engine. It has a factory long block with a factory cam and I converted it to a carb. It had a Performer RPM air gap and a 650 carb with 1 5/8 headers..

Here is a pic of it on the dyno.. they have a video of it somewhere

here is a pic of me, pointing to all the blow by that pos 160k engine had

here is a pic of the engine in the saleen that made 260hp

and here is pic of the car that had ran 11.50

Qwiknotch

honestly, it was probably the ring gap and the cam...

I went through 6 cams and picked up 75hp messing around with cam profiles and valve spring rates and ring gap

tylercrawford

Do you have a degree in sandbagging?

This is like corral with the pros saying they made 330rwhp with the stock intake and untouched gt40 heads.

We had a factory stock car on the dyno 2-3 years ago and it made right at 312rwhp ("untouched" e7 heads, limited intake choice, "factory" cam)

The guy had $8,000-9,000 in the motor.

[QUOTE=Damian;441982]So no n/a 302 can make 420 to the wheels? ha.

[QUOTE=b00sted;9703011]it's pushing it. My friends 302 with 8 lbs made around 440 with a fully built motor

Qwiknotch

Ok, now add gt40p heads, a custom cam, a dual plane intake and a 650 carb

All I am defending is the fact that 400+hp can be acheived with a 302 and basic heads
you do not need some sick *** non streetable 302 to make 400+

Bill Glidden did an engine for a guy... 308 inches, victor jr heads (ported), victor jr intake, custom hydraulic roller cam and 10:1 compression. That engine made 609hp at the flywheel

well lets see.. i had a 92 lx with a built 306 w/ old school tfs iron heads fully ported,wolverine 5105 cam, gt-40 lower, w/bread box upper, 30 #'s, BBK LT"s,tremec tko t-5, 4.30 gears and with the rest of the bolt on's mass air, throttle body.. blah blah.. and all she had was 390 to the wheels..n/a..

[QUOTE=stevied916;9703024]Than he needs to up the boost.

A stock 5.0 with a small blower/turbo can make more than that FYI.
