Depends on who you have do your port, steggie, lfp, d'agostino racing. I would go with steggie though if I were you. They just came out with a new stage 5 and stage 5+ and both are making awesome results. A stage 5 runs $695 plus shipping. Some shop would probably charge $200+ to take off your blower and put it back on.

i had a stage 3 port, they run 495 + shipping from steggie, for all supporting mods and a lower puleey you would be at around 1700 + labor of probably about 500 bucks to do everything.

that price does not include intake exhaust mods though or tuning afterwards.

how long do you all think your motor is gonna last get 600hp out of a 281? I have to say unless it is a track car, why? i put a smaller pully, headers ,cat back, intake and had it dyno 456 rwhp. Have upgraded the tires and brakes. And I have to say
It will not stick to the ground, It doesnt do to bad but if you arent going to a coil over suspension why? At this point gut the inside and what ever else will take weight off and put it on a trailer and race it.

I think the first think that should be done is brakes and suspension, the exhaust on the car is a joke stock, I had to laugh when I saw the manifolds

I raced a corvette the other day 125 mph in a long turn and the car sways badly, the down fall of these cars is not the drive train as much as what I said above.

I did smoke him!
