I'm assuming flywheel HP as well, no way does that car make over 420RWHP. I'd do it, I've had 3 T/A's, the first 2 heads and cam and daily drivers, one made 400RWHP, the other made 440RWHP. They are just fine as a daily, under part throttle and at daily driving RPM's they BARELY make more power than they do stock, when you get into WOT and higher RPM's is where the power gains are, not what you see daily driving.
Thats why manufacturers rate their vehicles at the flywheel? To regular Joe, engine numbers are what they think when they hear a HP figure.

Yeah, 490 might be close to the fwhp but NO WAY it makes that to the wheels. Regardless, I wouldn't make that switch unless you were able to buy another daily driver. I know for a fact that big cam autos suck in city traffic. MPG is greatly reduced, bucking and surging issues, extra risks for being pulled over by cops for loud exhaust, ect.
Also I would be very skeptical of this guys car. Why is he trading a car he put so much time and money into for a stock car? Most people go forward in mods, not backwards. It's possible he knows of expensive issues that he wants to pass onto another.
I would pass on this.

I agree. There's GOT to be a reason why he wants to get back into a stock car, and I'm sure it's not just for the challenge of building one up again.

I guess the deal might be good if both of your cars have some hidden issues.

2.MPG does decrease in town traffic,but my car got 17mpg on the highway.Now he didnt say about highway or town driving,so not sure there.
3.Loud exhaust problem? YES, but I have a factory SLP muff and it keeps it somewhat quiet.No where near as loud as dumps.
4.I have the same cam and auto with only a 2500 stall and 3.23 gears and I have no problems.Except for the y-pipe bang until I fixed it.

I do agree with most, PASS! Do the work yourself unless you helped build that car.

Not true. You have two problems. The stall is WAY under sized for that cam and the gears are killing your performance as well. Your car would be a LOT faster with 3.73's and a 4000 stall.
