Hey everybody. I just picked up a DSS 306 with trick flow heads (stage two porting). I will be running a edelbrock rpm intake 70 mm tb. I was wondering what size injectors should I go with, also what mass air? Thanks in advance.

i would say 24 lb injectors, but what kind of advertised horsepower does this thing make?

as for mass air go with a 75mm.

76 c&l and i would go with 30lb injectors.I don't think they make a 75mm mass air.

fordguy17

pro-m does.

It is estimated at 360hp. So with my intake setup I am hoping for 320 to 330. I tried to download pics but it wouldnt let me change the file size.

is that to the wheels? if thats flywheel hp, i still say 24lb'ers are your best bet. 30 lb injectors can sometimes cause hardstarting and other drivabilty issues.

true, true, stangpower.

Everyone i know runs 30lbs with the h/c/i cars with no problems at all even my freind with a ported cobra,custom grind and p/p stock heads has no problems,and plus you have enough injector if you want to go farther with your setup.

fordguy17

do they have custom tunes or use a tweecer or what?

cammedlx

Nope just alittle owner tuning,other than that stock computers and everything so that's why i say 30's,The only problem they do have is a little rich condition at idle but nothing major so soon i will invest in a set of them.
