Nice mod list, but I dont think 300 horses with stock cam and heads...

Until that nitrous....lol.

You seriously never know though. My old motor had 155,000 miles, ran 14.5 at 95 with FULL exhaust, smog pump eliminated, electric fan, Cobra intake...... It was slow for what it had but it seemed to run ok...til we opened it up. Sludge so bad I dont know how it had oil pressure......fried piston compression rings....bent connecting rod cyl. 8...

On a used motor, its VERY hard to estimate horsepower.... Just saying, be careful. You never know.

you wont really be close to 300 hp. maybe 230-240 at the wheels, kinda pushing it though. whats with the 36lb injectors??? way too big. to get around 300hp you really need good heads and cam.

Need to do something with those stock heads... the intake setup you have sounds WAY too big for those stock heads..

I agree there, I'm still running stock 19's on mine and I'm doing ok. 36 is more suited to supercharging IMO. I wouldnt really go bigger than 24 on a streetable N/A motor

I can't beleave I wasted my time reading your weak list.

Don't be a douche....

Got the BBK ssi intake from Brothers Performance about week n half ago.. Looks alot different than the regs...

 

[NightStalkersSO]

Holy fuel! You don't need a 255lph and 36 lb injectors for what you're running at all....and 41 psi on your fuel is too much too...tune that down to like 36-38, save yourself some mpg that way. If I were you I'd get some gt40s, 1.7 rockers and an aftermarket intake, that'll give you closer to what you're looking at getting for good budget

 

[stang2841]

you got the BBK SSI intake arready?

what do you mean it looks alot differnet in the regs?

perform good or what?

thought that was coming in fall?

hows the hood clearance ?


id kill for that intake

 

[ucanbeatme]

Like the holly systemax and the stock and go into 1 big plenum but the way that the bbk is it goes into 2 different smaller ones.. I have notice a difference in the performance over stock.. Its only a little taller than the stock but i have a 4" cowl so i dont know if it would fit with the stock hood. i pretty sure that i will.. It was real easy to instal and i like the performance

 

[ucanbeatme]

The reason why i have the 36lb injectors because i am getting nitrous and soon to a turbo.. And since i had the intank off and new rails i just thought that i should just throw them in so didn;t have to take everything off..

I'd say you're about 80 hp shy of 300 at the wheels, if not more. That intake on stock heads is probably robbing power, along with the bigger injectors.
But, throw on a set of good heads and a cam with the other items in your list and you'll be at 300 rwhp.
