TTI 1-3/4" shorty header power potential

[Machineman63]

Its probably come up , cant find it.
Has anyone tried to make power with these as an option to the Schumacher headers?
Street based 440 trying to make 550Hp /550Tq and retain power steering without breaking the bank. I know those numbers are very optimistic on the Schu's 1-5/8" primary....

All feedback will be appreciated.

TTI are good headers. I've run their shorty's on a 273. I would say that they are as good as the Schumacher's .I've run the Shumacher's on 2 big blocks. A 451B and a 500RB.Worked good on the street. Yes you will give up some power compared to long tube 1 7/8''. The 451 Stroker was in my 65 Belvedere It ran 11.90's in full street trim with 4.10 gears.And street slicks.
