Just looking to see if anyone has dyno numbers with an X303 cam, also if you could include the rest of the setup.



Before it turns into a "buy this cam" thread, the X wasn't my first choice but it's tough to be FREE :D

No dyno #'s but with a 650 double and a torquer2 intake on a stock long block with 4.30's its real fun!



I'll be running some ported/polished 351W heads with 1.90/1.60 valves, a Wieand Stealth intake and a 650 double pumper, with 4.10s for now but i may be switching to 3.73s. It should make for a fun/reliable engine, i'm just curious what kind of numbers to expect. My buddy put out around 260hp with GT40P heads and this cam with a cheap Chinese EFI intake...i'm thinking (hoping) around 260-270hp since my heads are a bit wilder than stock GT40Ps. It's a decent cam but certainly not the first i would pick, but this is gonna be the ultra budget engine build so i'm taking what i can get.
