Default 396 lt4 rwhp guess?

anyone wanna take a swing at this?

untouched 195cc afrs, unported gm lt4 intake with the exception of a 58mm tb, 236/244 .585/.580 112, 11.5 compression. pacesetter lts, no cats, magnaflow catback, lingenfelter cai

6 speed, moser 12 w/ 4.10s

im hoping for 450 rwhp but im starting to think its a little high.

my 396 which is nearly the same as your motor, except i have a ported LT1 intake and ported TFS 195 heads, made only 390 RWHP on a mustang style dyno, through a bottleneck 2.5 - 3 inch catback exhaust, loose 3000 stall, and 4.10 gears. The SOTP tells me ALOT different.

id guess around 430 RWHP on a mustang dyno.

i love how quiet my custom magnaflow catback is, but its clearly a weak point. duals FTW before any y pipe setup even a 4 inch cutout. i have a 3 inch cutout and it doesnt feel like i pickup anything but attention when i floor it lol.
