Where would you shift my combo?
My combo is a 10.6:1 355, hotcam(218/228 .525 I/E), aluminum L98s, HSR, 700r4, 3.27.....
Where you you shift this combo? I currently shift 1-2 at 6000rpm and 2-3 6400 but would like to hear your input.

I would think the HSR can rev higher than that. As a rule of thumb you are suppose to shift about 10% RPMs past your peak HP.
If there is a dyno in your area I would suggest taking your car there.

You should shift so that your avg. hp #s are your highest over the range which your engine drops its rpm. I think that cam will peak in the 5800-6200 range. I know of that the LT1 guys are shifting in that range on stock heads and bolt ons.
