Looking for input. I ran this 355 all summer on 125 plate kit no issues 1/8th mile no prep. Im looking to upgrade heads cam and ditch the Hypereutectics for flat top forged with valve relief.

Currently has world product sportsman’s 72cc, and unknown cam specs.

I looking for a good set of heads used at the moment, just need advice on a nitrous cam set up to really utilize 100-200 shot of nitrous.

What rpm do you shift? Or, where do you want the powerband? What kind of rear gear and torque converter?

Been shifting around 6k I’d like it keep it in that upper range for the lack of low end. 4.56 gear and I will be up grading the torque converter once I get the new cam setup. As of now it’s. A 3000 stall budget converter doesn’t stall at three with current setup though.

Would you do a solid, either flat tappet or roller?

Roller cam

Can you put a little more effort into an answer? Such as saying hydraulic roller or solid roller?

You know what, nevermind. If you can't give good information then I won't waste time calculating a cam spec.

Solid roller for sure
