input please

[swammi]

im getting ready to install my new engine this weekend , i need input on which intake to use! the engine is a 327 stroker and am running gt40 heads with 1.94 160 valves . i have a tubular upper and lower gt40, a cobra upper and lower and a trick flow track heat upper and lower. my cam is custom lunati 542/554 286/294 ! any input would be great. also witch injectors 24's or 32's i the mass air for both and which throttle body. 65mm,70mm,0r 75mm .thanks folks!

I think I would do the GT40, 24# injectors, and 65 or 70 t/body.

I second that motion. If you plan to drive it around town.

I third that, and I would go with the 70mm TB as the GT-40 series uppers (Cobra,Tubular, and Explorer) have 70mm TB openings.

...I would go with the 70mm TB as the GT-40 series uppers (Cobra,Tubular, and Explorer) have 70mm TB openings.:think: I swear I had to "clearance" my Cobra Intake for a 70mm Throttlebody? Maybe I imagined it. :shrug:

Either way, there probably won't be a noticable difference in 65 and 70mm TB. Sell one and fund some other go-fast goodies! :nice:

Nope. I only had to clearance mine just a little for my Accufab 75

I agree. that is why i suggested either one. There will be no difference. If the 65 is a factory ford piece (like from a 93 cobra) I would use it over the 70mm

FWIW... I had a BBK 65mm on my car... then swapped to a 70mm Holley billet. Didn't like the "feel" of the pedal vs. throttle so I went back to BBK 65mm. Felt quicker off the tip-in with the BBK...but I think it's in the design. :nice:

I dunno, but it seems to me that with a cam with that much lift & duration, I would want the trick flow intake with a 70mm throttle body. Those GT40's would be the only real bottle-neck. :shrug: Either way, the 24#'s should be adequate enough.

well back to cam talk i have that lunati, also an e,f, and x do yall think i should go a different route with the cam. what about an e with 1.7s:popcorn:

[EHardy1971]

What valve springs are you running? The GT-40's will flow up to .600" lift in stock form.

[swammi]

ford motorsports a50 spring good to either 560 or 580 lift

[EHardy1971]

Yeah, I'm familiar with those. Honestly, I'd go with the Lunati, as Fords really need more lift and duration on the exhaust side to breathe better.

Keep the cam and use the GT40 intake and the 30# injectors.

Whats the compression of this motor
