What Sr20's that on, i have had a few 2530 over the years, back in the late 90's when they where $3G secondhand...lol, but on the old redtops with standard cams they would get 18psi by
3800rpm and 228-230rwkw and be out of puff on 98 octane, I really like them,., i still have one sitting in a box that i have nothing to use it on,, what are they worth now in good condition? . 3500rpm would be feel epic compared to that
cheers
