i agree 100% alot of people claim the 500 hp mark and had the dyno sheet but it was on a dyno jet not a mustang dyno but just because they only run low 12 and dont get over 120 does not mean it didnt make it means they cant drive lol.500 it can be done but its not that easy not if you want it N/A

I don't see how a 351 is easier, with a heavier rotating assembly, bigger mains, and also the added weight of the block.

To the OP, if you keep it N/A do an early model block, keep the ratating assembly fairly light. Put the heads you have in the hands of the right person, an off the shelf hydraulic roller, change the intake. Keep it out of detonation, don't spin it to the moon and it will live and make 500whp.

are you looking just for the Hp number or a certain track time. my old 289 maverick ran 11:30's NA and that was before aftermarket any type head (mid 80's) and I know I was lucky enough to just have lil over 300 hp

Tiffiny

yes you are correct i never said you cant make 500 with a 302 but


you will never have the torque of a big windsor and you can make an honest 600 + hp on pump gas for about the same money and more reliability.....

The replies, thoughts, and prior experiences here are priceless. I know a few of you really have quite a lot of experience with 351's, 408's, 427's, etc.

I've had quite a few 302's, Turbocharged 306's Proturbokits (on TurboMustangs), Superchargers, Vortech S-trims, Nitrous, etc-

The closest on a Stang to 500 Rear Wheel Horses, was with the Turbocharged Setup I had on the 306. However it was around 440 horsepower at 12 lbs boost with a 64mm turbo.

I had an 03 Cobra, and it put a little over 400 to the rear wheels, but I didn't have the same love for the 03 as I do my Foxbody's.

I went with 87 Buick Grand Nationals, for a few years and they are a blast. I had Champion Aluminum heads, TE-45a turbo, Front Mount Intercooler, and Alcohol setup with 18lbs of boost, and Chip. It put over 530 to the rear wheels and with only a 3.8 liter V6!! That car was amazing and had pulled really strong.

I'm since back in Mustangs which my 91 LX 5.0 Coupe is just beautiful. It has a 306, with Ported Stock heads, Intake, and Vortech S-trim. Had it at Ramseys and it put around 340 to the rear wheels with the Stock Vortech 9lb pulley.

I'd like to do something different now. Accomplish, 500 to the rear wheel or very close Between 450-500 and use a 351 converted to a 408 or 427 to accomplish this.
It would be nice to be able to have a little less compression so it can in the future have the Vortech S-trim put on, and use a little boost to put it well over 500 ponies, and then some..

If any of you have recommendations as to what shop, and group of guys can help me get this done as conservatively as possible ($$$), please let me know.

I'm considering Fordspeed, and Realspeedparts, Rob or Walt to try and help me put this together. I'd like to use Fordspeed, because he has the dyno there, and can just do it all at his one location.

Any other advice or recommendations is highly appreciated. Oh, I'm also wanting to try and use my Twisted Wedge Heads on this setup. I'm going to need a new intake. Any advice on the intake, and probably going to need more than 42lb injectors as well, right? wasn't sure... you all know more than me.

Thanks in advance guys/gals- ( I know there's a few ladies on here with some killer Mustangs)

I think YamahaGuy(username?) is tweaking a combo that sounds like what you want.

Whoever built those engines should find a new profession.

A friend of mine has a basic 67 Camaro with a 390 small block. Naturally aspirated, and runs consistent low 11's- her best, (yes she) was a straight 11.01 run against the new Camaro SS's and it was just a naturally aspirated all engine car. Nothing else. A turbo 350 automatic trans, and the basics. Really sweet. She lives over in Safety Harbor area.

If she can run a 390 C.I. small block engine in a 67 Camaro body- and run low 11's like that- without any power adder, or nitrous, or anything like that- then I'd like to see what I can have installed in my coupe to be very simlilar like that with a 91 Coupe

Im sure you all know better than me- All I want is to see what ya'lls thoughts were on creating a powerful Naturally Apirated setup without power adders for now.. and the 2nd thought I had is, without having to spend way too much money to do it as well. That's the challenge, I guess..

I guess too, it comes down to how much money i'm willing to spend... I know that.

HP to cubic dollar, how much money is what it comes to. Fordspeed or Realspeed either is quite and both race, so they know what it takes to run the times and not guess at a combination.

...were you saying that that 408/427 setups you referred that to, should of been putting out more power?
