probably about as much as the t5 will handle. i would guess around 300 at the rear wheels. there was a guy there who probably had something similiar to your 351 and comparing it to my 351 which is rated at 385 he put down 330 range at the wheels, and my car is pleasant to drive. it's all dyno magic btw, only good for tuning or comparing two cars on the same dyno or under same conditions with similiar dyno setup.
