I changed to the short ram tubes on my Hilborn EFI, now I can see whats in front of me, those long sweeper turns were pretty sketchy on the streets LOL

Does the car perform any different with the short stacks ?

That is one wild-looking unit. I can hear it by just looking at it.

Either way, it looks bad ass.
Weren't the other ones gold?

It still makes about the same HP. it just changes the RPM torque curve. since our Hometown drag strip is closing, I decided to put the short stacks on for more street driving, I dont know WHY it took me so long to do this LOL, it only takes 5min to change them out, it makes it much easier to drive on the street & then if I go to the track I can then change them to the longer ones, sometimes my BRAIN DAMAGE is glaring

Looks great  :cheers:

Might trade midrange for more high rpm power.

Did you need to remove any fuel from the mid rpm and add to the top?   

If you have a loose enough converter for it to still 60ft well I would give them a try at the track (with higher shift point if your valvetrain is still stable)

I have run these at the track, have not been able to make a good full pass without some kind of a fuel delivery issue, wrong fuel filter, bad fuel pump relay ECT,ECT, with the Long stacks it flashes the converter 5100,ran 11.04 @ 123 around 2000ft laying down relay crapped out on & off ,, short ones flashes 4700 . 11.07 @121 500ft DA, to small of a fuel pump, will have to do some data logging for the fuel map
