Not Ranked
My car came with the R. If I were putting one in, I'd likely go SR because you won't likely miss the last 50hp.
I set my idle around 1000 rpms, it feels best there. Around town it drives fine, no bucking or issues.
The car is light, so you won't really miss the torque loss below 3k, but expect to downshift when passing sometimes. The motor does not like to lug around under 2000 rpms, drive accordingly.
I bought a tuned AED carb from Randall at cobra valley- that's the best motor upgrade you can make, it drives so much better than the holley 4150hp it came with. Much more responsive at thebmiddle/bottom. Just order a carb and run it from the beginning with the aed.
