i went holley high ram, sorry hadnt had any runs yet since im replacing the trans, im ok with sacrificing torque for rpm, reason being ill be launching on a T brake at 4500-5000 rpms

Well i lost about 35 hp and tq when i dynod before i swapped to the holley but that was on my 5.3 same heads smaller cam dynod around 417 with stock intake and 383 on the holley. I want to change the stall to a 4k atleast but i like driveability with the one i have now

You should move to the Holley Mid-Rise, the look of the Hi-Ram but bring your much needed lowend/midrange TQ back. You don't have the converter to run that Hi-Ram without it really hurting you.

Thats what i was thinking i can use mi hi ram for my boosted coupe mustang project i have going on and try out the mod rise i should dyno before and after though. I am gonna change the cam since this was specd for my l92 6.2 gxp
