Wow, this little thread sure blew up! lol Nothing new in the works currently except that I got some 3.73's instead of the 3.55's I had originally planned on. I need to find a set of wheels to put some drag radials on. I have heard 275/60/16 will fit on the stock pony wheels?

Definately gold is much more better

Alot of good info !!!!!!! Hey darrell , do you think it's possible to achieve 300 whp w/ ported gt40 heads ,ported gt40 intake ,and either a mild cam ,l/t, o/r h???????

Thanks ,I have someone selling this combo for really cheap.I was thinking of running this till I get my 347 finished...........

Yes it is. There are a couple guys on the Corral doing this and I think they are using the stock HO cam. However, buy the time you spend money to have the GT40 stuff ported you might as well buy some real heads and intake because you will have that much money into the stuff. If you are going to run GT40 stuff, don't waste the money on porting them unless you are racing a class that requires those parts.

That's exactly why I asked you the question . So I can get a better grip of whats the best way to get some power to my 5.0 .....

Thanks again Darrell.......

my friend just made exactly 300whp on

afr165s
older performer rpm
e303
boltons

[BEASTstang]

So it should be pretty close with a more aggresive cam,and better intake ???? We shall see .....

[grnstang]

my friend has an 88 LX. ported gt40 irons, comp xe 272 cam, and a cobra intake and made 313 rwhp and 354 rwtq i just saw it dyno again on saturday. it has lost some torque since the initial dyno last spring...we think the rings are bad because it smokes some and uses oil...

im still calling bullshit on the tq

[grnstang]

alright im gonna go get the dyno sheet. i swear to god its crazy

[BEASTstang]

But that would be great numbers for a budget build !!!!! Even if the tq is wrong ...lol

[grnstang]

it was seriously like 370 something about a year and a half ago on the little 15" 10 holes. its been having some issues lately and with turbines w/ 275/60 M/T drag radials it made around 350 tq the other day. i havent been to the shop in a couple days ill get a print out of the dyno sheet and scan it on here

[grnstang]

keep in mind that his dad is an expert tuner & owns the shop so he had plenty of dyno time to get it right...we cant really explain it..just think it was the perfect combination..everything complemented eachother well

Hard to believe.... Joe "Pure Stock" makes 370rwhp out of his 302 and it is putting down 362rwt.

Horsepower = RPM x Torque / 5252

Torque = Horsepower x 5252 / RPM

Those are the formulas always. Torque and horsepower also cross each other at 5252 rpm always.


What rpm was the horsepower and torque at on this engine?

why exactly does this happen?

Because horsepower is a calculation of torque and rpm with 5252 being the constant which is a number derived from a few mathmatical equations. Since 5252 is the constant in both formulas, that is where the horsepower and torque cross on the graph.
