Guess my numbers.

Anybody wanna guess what it will make? Car has 9.5-1 compression. Its set up for a blower which I'm gonna do later on. Its an auto with low compression so I don't expect real big numbers from it. 450 would be nice. A few people have said they think between 430-450. Mods are in my sig. We shall see.

If the Brute Speed blower cam is 232/240 .595/.608 lift and made 865 rwhp on a Mustang dyno on an 402 LS2 with AFR heads at 12.4 pounds of boost, i would guesst that 402 LS2 would make about 472 rwhp without boost...between the heads, cubes & the bore size 402 LS2/AFR vs 383LS1/ported 243 I would guess there is 35 to 45 hp difference..so 432 with the auto & 9 inch claiming another 15 to 25 hp so 412 to 422...

420 hp + or - 5 hp is my clueless guess, if the converter is locked 430 + or - 5 hp on a Mustang Dyno with same test standard/calibration.

420 Mustang Dyno and 435 DynoJet my final guess.

Be lucky if it breaks 410 on a DJ.
