LOL! Pretty good April Fools joke. Anything that says "ford" is replaced with "chevy". Nice.


BTW, my buddy had a chip made, even sent it back twice and they finally gave up and told him that they COULDN'T get the rev limiter removed/moved up. Don't know what the deal was? We call it "the little motor that could", as it was still completely stock bottom end(never out of car), until just a few yrs ago. He finally bought a fresh shortblock(stock parts, std bore, but balanced and fresh), little bigger cam, carb and gone 11-teens with it. He does wind it up there. Everyone looks for either supercharger, nitrous or think it's a 347. Nope, I know so, I helped build it. He's spent the last 22 yrs tuning it and working on it.

I took my 88 to mustang specialties they got a guy there named Scott..Does all the dyno tuning..He just reset it..I had him do my truck & came out great..He tunes it on the dyno then burns a chip for it..Its expensive like 600 bucks. A lot of dyno time..But he sets the timing curve & fuel air ratio & idle for cam & what he calls cruise efect.Sets all the up & down shift points & adjusts the torque converter..Gets rid of all rev limiter & speed limiter..egr...Thermastat so we can run what ever we want..Yeah i never had my 88 stang to the track at that time there wasnt any tracks around..I think i might have run a high 13...Had a 93 coupe that ran low 13s...But yeah those 302 stangs are fast they can run 11s with just motor & no stroken it i have seen them do it..A lot of motor work...

Get a diesel!

After having a 460 in a 93 F250, diesel is the way to go... my trailer with it loaded is roughly 10000 pounds, and I have no issues going the speed limit...

Also we had a motor home with a MAF 460 in it, and that would go, but the engine just did not allow us to go the speed limit up some hills...


Diesel Is the only way to go when towing IMO. Not to mention 18 MPG versus the 7-8 i was getting in my Turd aka my 93 460 F250.

thing is finding a cheap diesel truck isnt nearly as easy. i dont really tow 10,000 pounds on a regular basis if at all (i havent yet but im not saying it wont happen). heaviest towing ive done is my 25 ft camper trailer or a one car trailer with car. an f250 or 350 is alot lighter than a motorhome and shouldnt have issues keeping speed up. and yea granted diesels get better mpg at the expense of higher price per gallon. I know my way around diesels and you can take a 460 to alot higher hp cheaper than a diesel IMO.

Right now and always will be, diesel is cheaper to produce than a normal gasoline. I am paying on average .20 cents cheaper for a gallon of diesel than I am for a gallon of 85 octane gas... for the last two months.

My 460 F250 93 did not have much of a problem doing the speed limit by its self even with a 4 icnh lift and 35 inch tires... but that was with the pedal mashed...

My diesel will gett better gas mileage, has more miles, has about twice the power, and can put another 100-150 hp and foot pounds for less than 1000 bucks...

only disadvantage to the diesel is the smell, which I cant smell, my mom cannot stand it.

After my dad only ever owning a Gas motor truck/ car/ motorhome, this diesel has impressed him on how it will pull anything and runs so strong.


and another thing to consider...

i got my PSD 97 by trading my 93 460 for it, i had 2200 bucks into my 93 after having it loose oil pressure and have to put new lifters and pushrods in it... 200K+ on the diesel when traded and 187K on the 460. straight across. The deals are out there. Just dont get an IDI non turbod diesel.

where i live diesel is about an extra dollar per gallon over premium gas.. i dont need crazy towing power, this is more of a truck to screw around with and have fun. people have told me if i want to have fun to get a stang or something but ya cant take one of those into a mud pit or climb over rocks can you? lol

Mustang matt sounds like your 93 460 wasn't running right at all

We have a 99 7.3 psd 250 2001 psd excursion and 06 350 6.0 psd I drove the ex for a year before getting mine I was unsure about going to gas but since getting used to the 460 it would be hard to go back

what 460s really like is about 12:1 compression and the kasse p-51 heads with a victor and a dominator, that is a pretty basic 460 build that will net you a bunch of power and it's not too expensive either maybe 5-6k depending on where you get your parts, it goes without saying you'll need roller rockers, forged pistons, good valve springs, light weight valves and retainers if you want it to rev and at least a hydrolic roller cam

but i think that would be a really fun build and you'd be making more power than you knew what to do with even with the heads unported, get the cam a size too big so that if you want more power you can just port your heads and you've got it

or you could just stick with stock heads put on headers and a wimpy computer controled cam and an intake

im not saying anything bad about carbs they are cheaper and easier to build as my dads drag car is kickass to me (70 dodge dart) but efi can get to the same power level just costing more money which is really the only downside to me. 12:1 compression doesnt sound very streetable to me either. 5k would get a nice vortech supercharger for a 460 efi as well.

i've built a bunch of aluminum headed motors that run 12:1 compression with pump gas (premium) just have to get good quench my t-bird has 12:1 with iron heads and it runs on 96 octane race fuel

and i think you would make more power with a p-51 headed hydro roller cam victor intake and a dominator than a stock vortech supercharged 460 with efi- they really cost 5k? that's a ton of money per h/p you get

i agree its a lot of money per hp. just checked and approximate cost is 4200 bucks for the whole kit. it runs at 6psi and advertises a gain of 81hp and about 75 ft lbs (no not alot for the money) but i havent found any other supercharger kit other than the vortech for the efi 460.

i was going to say a 6-71 blower but...you gota use carbs or some exotic fuel injection kit, but just think how nasty that would look with a 6-71 or 8-71 poking it's way out of your hood!! they can be had for closer to 2k for the whole setup carbs and all if you find one on ebay and you can put tons of boost into the motor till you pop your stock pistons
