Could be, the previous owner said he replaced the shortblock w/ one that had forged rods and pistons. He didn't say anything about it being a stroker though....

How much would you pay for the car....honestly.....if it had only 17K miles??

Think about it, at 17k miles, the motor is just getting worn in. Imagine how hard it had to be run to have to "replace the shortblock"

Thats exactly what I paid - 20K. Rims and all. I thought it was a fair deal considering the rims. I get alot of coments on them.
The new motor has 7k miles on it. As you pointed out, may have been run hard though, so only 7k miles doesn't mean much.

This thread has gone a bit far, so in summary I am going to answer the original question 500whp is ABOUT the realistic ceiling for a street car with stock cubes, 93 octane, hydraulic roller less than .625 lift, no power adders, no dope and no quantam drive. I think I covered it all.

The torque curve also looks a bit odd because the scaling is different for hp vs. tq.
I love all the smack this guy is talking and he doesn't even know squat about his own car.

The original post asks about maximum n/a 347 rwhp, but does not limit it to street cars. This question came up a few months ago and a number of people felt like a 347 could make over 600 rwhp with high compression and leaded gas. I agree.

It looks like a stroker dyno graph if it's N/A like you claimed. Again, you are either clueless or full of it because a month ago you posted:

What's the whole point of building an all out pump gas 346 that isn't drivable anyway?
Hell, F1 cars are making >900hp on 3 liters of V8. That is N/A with pump gas. So they idle at 5k and redline at 20k.
You can make probably 700whp with a n/a 11:1 346. It wouldn't be at all driveable and have a 1k rpm powerband that starts at 6k but with enough money (READ 10s of thousands maybe more) Anything is possible.
If you're out to make power...why limit yourself to the hard way?

This board has a wealth of knowledge but we don't like to put up with attitudes to much.
