Dyno Don headers feel a difference?
I am pretty set on buying Dyno Don's headers, but I want to know who here has had dyno dons headers (or even slp's 1 3/4 headers) in place of the 1 5/8 shorties that is pulling 300 rwhp range and has noticed a difference? Track times/et's/dyno are most welcome

Re: Dyno Don headers feel a difference?
I went from SLP 1 5/8" headers, Corvette heads, and ZZ4 cam to Dyno Don's 1 3/4" headers and LT4 HOT cam and went from 282 RWHP and 380 RWTQ, to 317 RWHP and 419 RWTQ. Some was from the cam, some was from the headers. My ET also dropped from 13.21 @ 107.1 to 12.80 @ 108.50. I still havent beaten that time yet from 5 years ago.

Re: Dyno Don headers feel a difference?
was there any tuning involved between the two mods or was that untuned?
