Hey guys i was surfing the net just looking at mustang things and i found this article on the CarCraft website.

From what i have read on different threads on this forum this seems too good to be true, but im not really sure. Any feedback is appreciated. Also say i wanted to do this combo, but keep EFI (instead of go carburated like in the article) and get a different cam but keep the bottom end stock, what would you guys suggest?

thats nuts! wow, i hope that is possible if it is i may lean towards putting my stocker back in. i am interested to hear what all the guys say. mike

I made 321hp to the tires with a hot motor

lose my cam, put in the stock one, would probably make 290-300rwhp

with 15% driveline loss thats 345hp.


even with GREAT heads, I dont think its possible to hit 400hp at the motor.



now, build a 408w with high compression, 225cc heads, use 1.7 rockers, advance the cam, and you could probably hit 400hp at the tires. lol.


so the answer is no, in my opinion, there just making up numbers for people to buy parts.

engine dyo results..lol rwhp is what matters, plus I'm sure they didn't have any parasitic hp loss for accessories bolted on to the motor, so after all that, you have a 320 rwhp ride

i never realized that could be achieved with the stock cam and displacment

320rwhp that is

people are under the impression that you NEED a cam to make power. Little do they know, the stock cam in a 5.0HO is actually quite healthy as is.

Infact, the HO cam is an upgrade to the cobra cam...

yeah you can do it just spray it with a 250 shot of the juice

Yeah, cheating dyno numbers, that may even be corrected for all you know. And while you CAN make 400hp at the crank at 6,000rpm in a 302, it would take a pretty well developed engine to do so, and it would require light valvetrain components and a light rotating assembly. But it's not likely to happen with the stock cam. For the cost of building a 400hp 302 you could build a 450-500hp 347.

In the article the AFR 165 heads they use are the "smog-legal" version. Whats the difference between the smog-legal and the non-smog legal? Im wanting to install these heads and eliminate the smog pump at the same time so would i be better off getting the "non smog-legal" heads?
