No stack injector will make the power of a tunnel ram. BTDT long ago. Tuned by you maybe  I've seen more than one Comp Eliminators car go faster with stack injection that it did with a tunnel ram with two big 4 barrel carbs. tuned by the same racers that were fast  Or maybe, just maybe (and it’s highly likely because over the last FOURTY YEARS I’ve seen very few actual carb tuners or ignition guys) they couldn’t tune a carb. I know Kinsler says their stack injectors give “each cylinder a precisely measured volume of air to each cylinder” and that’s not only wrong, it doesn’t matter. There is a reason why you don’t see nearly as many stack injected cars out there as you did in the 60’s through the 80’s. I stand by my post. Stack injectors are for nostalgia, not making power. You dont see many 8stack EFI set ups because people are afraid of them, and EFI 8Stack has not been around for very long.

Getting the closed throttle 8 blades open the same amount is a [censored], i use a small flow meter on each runner to get them balanced [video:youtube] https://youtube.com/shorts/Vn8igQFrOis?feature=share[/video]

I had a little bit of experience on the Roush crate motors with 8 stack injection. Wasn't that engine in the white stick shift Mustang you brought over to my folks' place, that we buzzed around in? That was a fun car, I remember it running great, made an impression on me.

Blusmbl I don't plan to run an IAC, I will drill all the runners for a vacuum line in order to make a small chamber for a common map signal. I'll turn on timing control to help maintain an idle speed. I will only miss it on cold starts most likely. Right on- you should be ok. I think Roush only did it because they sold the 402/427 8 stack crate motors as turn key solutions that usually went in Cobra kit cars, so they wanted the best drivability possible when it was cold just to be safe. Also, depending on your cam, you might have to blend between alpha n and speed density off idle. Edit: Rich, yep, that was one of them. The white SN95 had an 8 stack 427 with a TKO 5 speed. We also had a red fox GT hatchback, it had an 8 stack 402. The red car eventually got a 350 Chevy crate motor, then an ex-Nascar motor, then a milder carbureted Windsor. An old coworker finally bought it and now uses it as a track car.
