Even the 5.0 had an awesome sound. I've been told it was the exhaust setup, firing order, and OHC. Maybe it's a mix between all of that.

i asked john for you. here is HIS quote to me today. i dont know who george is, but he isnt john mehovitz, but this is:

i have read that you use a teksid for your pro engines, is that true? i figure i need to deburr the block for safety at the level.

The Teksid block is the only ones we use. Theres plenty of other stuff we do to it to make it survive. Just keep the bores as small as possible

BTW a cobra aluminum block IS a teksid block. A 99-01 cobra WAP block is notoriously weak. teksid blocks were manufactured from 92-98. 05+ aluminum lock are as strong as TEKSID's for the most part.

my guess is john knows better than enyone else what HE races. i build turbo modulars. im going to start building 1000+ rwhp modulars from here out. which isnt really that much hp for a 4v modular.

where are those 4cyl 6 second GASOLINE NHRA pro-mod/street class cars? surely they would be running and winning in pro classes.

it takes 2300-2500hp to run 6.30's in nhra pro classes. these are 2500-2600 lb cars. i seriously doubt a GASOLINE POWERED 2.7liter toyota can handle 2300hp.

these is a 4000hp V8 arias cut on half nitro car out there. 4.8liters. nitromethane. 1/2 of a topfuel engine. i dont seriously count that.

Are you talking about the older HO 5.0s, as in the '82-'95 (or more specifically the '87-'95) versions?
I do agree that their awesome sound might be due to a combination of both the true dual exhaust set up and their firing order but I don't think OHCs had anything to do with it considering that they were OHV motors.

JD_AMG

Exactly, so who cares if the fully built drag car is using some stock parts or not?

Not sure but if that is from John it is straight from the horses mouth but strange theres a discrepancy. George works at Accufab and is an extremely knowledgeable guy(that quote was from a thread about the new 5.0 and how they were hoping to pick up a lot with the cougar due to the fact that the cam timing can be changed on the fly as they were having problems spooling turbos any larger).

I'll try and shoot him a PM, he's not a shop bitch either

You guys are going in circles with retarded logic.

camaro98z28

Do a search yourself.. I found it on Youtube and Google. Yes 4 cyl 6 second cars. Thats the way it is.

assasinator

tell your friend to ask john if i emailed him directly about this.

88blackgt

I believe you did, I just find it strange that theres a discrepancy.

assasinator

there's no discrepency, if your contact said he used something else he's mistaken. not a big deal really, so no calling out. but it is important to realize just how strong stock stuff is and what it can do without having to purchase aftermarket parts. stock ford parts are extremely strong. for exmaple.

a 5.4 nvh block can handle 1250 hp before it distrorts. a GT supercar block can handle 2000hp, a navi generation 4v block can handle 1400hp. The stock cast 4.6 crank can handle 650rwhp. all late model 5.4's have a kellogg forged crank.

the new 5.0 block will be no different, but possibly be even stronger than a teksid. BIG hp chevy LS guys use an iron block from what i've read. With ford there's no need. the stocker is good. if ford uses a kellogg forged crank with the 5.0, a simple change of the rods and pistons and you have a bullet proof piece. we know for sure the 5.0 rods are DESIGNED for a 7000 rpm redline, not the 6500 of earlier rods. they will be stronger than earlier mods by a small margin. Keep in mind this is 4v. we are talking pentaroof detonation resistance. 2V limits are mainly because of detonation resistance that 2v doesnt have. we wont know until people start throwing rods how much they can take, but my suggestion would be to reduce the rpms to 6000 and take advantage of 350+ cfm@.475 lift these heads have. i know that a 10:1 4v with stock rods can stand 500-530 rwhp, with 500even being pretty safe. Of course Tim Barth or Eric Brooks need to tune it. 500 rwhp is only 8-9 psi with a turbo on ealier 4v. they flow 233. these flow 350+. you get the idea.

All this tech talk, but any news how fast the new 5.0l is going to be?? updated info? This might be the return of the faster N/A mustang GT over the Camaro...nice; GM will have to step up into the game!!

holy crap, this thread turned into a ***** measuring contest, but everyone is measuring someone else's, saying it's the biggest.

Ya I've ran into a couple just tonight and its really getting old. I'm not about to start a fuss but he knows what he's doing, he just acts dumb. Sucks there's no dyno numbers

I should have re-worded that. The last part as meant for Mustangs in general, adding recent ones to the list. I know the 5.0 didn't have OHC.

Ke^in

Talking about me? I am not doing anything. You guys are freaking noided. Seriously. If ANYONE talking about Mustangs bothers you, you should be instead asking yourself why. Instead of projecting thoughts and motives onto people that simply don't share them. There is no conspiracy here.

I think it could be a close race, especially when comparing the automatic V8 versions of each car.
Among the manual V8s the SS does have a slight power advantage but the Mustang will have a weight advantage as well...it could even come down to gearing and which comes with stickier tires.
I do think that the V6 Mustang might just have the edge over the V6 Camaro.




Yes I'd kind of figured that.

I dont know if the 5.0l will have to get beefier drivetrain to support the new power. That could mean an heavier car. And it has to pass gov safety too..

We'll see what will happen, but I have a feeling that this new 5.0l Mustang will be faster than the new LS3 Camaro. One thing that is nice about the LS is that they react really good to mod and are easier to mod for the DIYers, so the LSx is still a win for plp like me, but not the 'general car enthousiast' I'd say.

The mustang is already ahead of the Camaro in some rag-mags with 100hp less, so if its on par powerplant wise, its going to be the new world wonder for the automobile press...They're still talking about hp/liter math, what better could we expect :S

LS1LT1

iTrader: (16)

Good points, the new transmissions and bigger brakes alone will add at least some weight to it over the 2010 car so it's likely that the weight gap between the Mustang and Camaro will close a little bit, though the Mustang will still be at least 150 (probably closer to 200) pounds lighter than the SS when similarly optioned.



True.



Also true.

Can't wait to see what this 5.0L will do, bout time Ford stepped up to the plate....13 yrs later...sorry 14....
