new intake and carb

[Mongo316]

Hello all, I would like to know if anyone has ever done a 2 bar to 4 bar swap on thier stang.

i have a 67 stang with a 351w mild build 4 speed toploader, it has a 2 bar carb so its ok off the line but runs out of steam quick and yes I am bored lol.

I just purchased a edlerbroke intake 351 rpm and a holley 670 street avanger.

i am wondering will this combo wake the motor up? will i notice a big difference? What should i expect from this upgrade?

any thoughts are welcome

Thanks
Mario

You will notice a difference, but you should also get a bigger cam to match.

What edelbrock intake did you purchase? You should notice a differance just from that swap as it will be more air and fuel into your 351.

Hey Guys thanks for the quick response! The cam in the motor is has a nice lope to it so i know its not stock. As for the intake its a RPM Performer.
Cheers. Mar

The only problem about your cam is you don't know the specs of it. Do you have stock heads? Just for referance I have a 670 street avenger and love it so far. If your heads have any work done to them it might not be enough carb for you.

I see your points regarding the cam! As for the heads they are stock for sure. I figure my car is only driven on weekends and in the summer (it stored for the winter) and a better intake and carb will wake her up a little. It seems right now around 3800-4000 rpm the motor wants more but the small 2 bar carb can't do it. SO ithought stick with the basics more fuel air. I do have full lenght hedders and flows (love them), so the exhust is perfect.

You made a good choice, but that cam is a wildcard at this point. No matter, I wouldnt be surprised to see 25hp at the crank as a moderate guess.
