300 auto. Street truck. Just for tooling around. 9.5:1 CNC promaxx head. Aussie 4 bl. intake. Headers. 2.72 gear Dana 44. (I know pretty weak gear).

What manufacturer do you like for the cams. I want something that will last. No hatchet lobes. Thinking power band range 1500-4800 roughly. Noticed the Crower 202/210 443/448 112. Probably using the Scorpion bolt down pedestal rockers.
Thanks.

You cannot use any of the advertised compression ratios or RPM specs in the cam catalogs. They are way off. Crower admitted the specs are in error
A 9.5 compression ratio is way to high for the Crower 202/210 443/448 112 and you need a bigger cam if you want to work to 4800 rpm.

What happened to the Crower 266HDP (19213) .456”/.461” 210/213 266/274 112deg that we discussed back in February?
What octane pump gas do you want to use?

Schneider 140H will work with 9.5 CR. I run it with a 9.75 CR. It runs decent on 87, but better on 91. Puts my DCR at 7.47:1
