Those are pretty solid numbers to the ground stock. What kind of gains are you expecting with the ls9 cam? I am not too familiar with that cam but I was thinking they were mostly being used for boosted applications.

and iīll boost it with a ht3b so that cam is great... but everywhere i looked i never found some numbers with that cam being N/A just for some guy with a 6.2 that gained 40 rwhp aprox. so it is mostly like a guide for some other people that wants to do the same instead of the old ls6 cam swap

and here in El Salvador a stock Ls1 on the same dyno as me trowed 285whp my brotherīs 98 LS1 with boltons and 273hr cam did 354whp 342rwtq so i think im pretty good with that results

tell me if you canīt watch it
