i had a 4.8 with high gears and tune among other shit.
302/305 is CRANK HP...so stock to the wheels it makes roughly 240/240 (after factoring in approx 20% driveline loss). After full bolt ons and a "tune" I'd estimate you're around 280/280 to the WHEELS and 340 CRANK.
I did all the work and purchase decisions myself before i every took it t the dyno, all they suggested was not running the dyno on the 22's and the 17's was the only other tires i had that fit. Thanks for your suggestion, i may try a different tuner
look at that, and at the same time throw some headers on there (long tube), as well as maybe checking into maybe a cam swap, if you are looking to get a decent amount of power being n/a and without swapping heads. lots of possibilities though
Why I stopped posting on gmfs. To much negativity
not negative, just calling him out those are pretty big numbers for what he said he has done. if he said 340 at the crank atleast its more believable.
