Estimated hp gain for this combo?

[Code Red]

How much horsepower do you estimate this combo will add to 302 with an E303 cam and basic bolt ons:

Victor Jr. Heads,
Performer RPM intake
JBA Headers
Magnaflow X-pipe with Cats

 

[bimmertech]

298.6hp/316.7tq

 

[Matt94GT]

Id say around 300HP as well, depending on tuning and other bolt ons more or less.

damn should run ok, those heads are pretty big for stock cubic inches, and throw that e cam away and get a tfs stage one id say with that combo would make 275 hp, this is all depending on tb size, header size? cats or no cats, please state these things!

Yeah, I keep hearing that about the e-cam.  how is the tfs stage one for idling and smog test?   My car is basically my daily driver.  I have long commute (75miles one way), so the Stang make the travel bearable.

My TB is 70MM, the headers are shorties, 2 1/2, the x-pipe has cats.

Also, do you think I will need to notch my stock piston for valve clearance with the Victor Jr.?

on my 91GT I had Edelbrock RPM heads (1.90) Edelbrock RPM intake (the old one) E303 cam, full exhaust, 70tb, 76 massair, bbk coldair, and the other small stuff- pulleys ect............and on the dyno 289hp and 303tq. It was a great combo it made good tq at low rpm and ran like a bitch above 3500 all the way to around 6300. My best time on BFG DR'S was a 12.39 at 114. Your combo is just like the one I ran other than your Victor heads, I think they are more for larger displacement motors rather than 302's.

Sweet! I hope get those kinda numbers.
As for the Victor Jr. Heads, I may have shot myself in the foot...I bought 'em because someday I want to go Turbo and possiblly even a 351. Trying to save money and not buy heads twice, I went Victor Jrs. Now I hear that may have to notch my stock pistons for valve clearance. :-[

Well you got a killer set of heads, so even if you have to make changes to your pistons I think it will be worth it. As far as the 351 goes with your heads :dancing6: :banana: no replacement for displacement.
