a MILD 347 would be 300hp at the wheel. theres plenty of guys with 350-375horse at the tire with nothing to crazy in there set up.
He might have just been playing with you, or just had his car set up like crap.
Im sure it was fun, and i guess you beat him if you call playing around a "race" but as stated it don't make sence.
First of all agreed. Doesn't make much sense. But I'm curious where you got those numbers from? In theory you could stroke a 1975 302cid motor to 347 and not even be making 300 crank HP, let alone at the wheels. Or a 5.0 liter from the late 80s GT will still only put out about 180 to 190 to the wheels stock. I think it'll take a bit more than just a bore & stroke and a 3 angle valve job to the heads to get near 300whp. I'm not breaking your balls just wondering what you mean by Mild 347?

I've never actually raced but according to my dyno numbers. I should run 8s on street tires.

I base most my 347 knowledge of Primetime5.0 in the 5.0 section. His last set up wasent anything TO extreme and it was a high 11 second car. His new set up which is pretty wild has him walking away from pretty modded 03 cobra's and head/cam LS1's.
Im talking about 205-225cc heads, pretty high lift/duration cam's, not real street frendly, and such.
not really "mild" but nothing nutty ether.

A kid in town and his father built a 347 for his 66 coupe. He used a FRPP e-cam, stock mildly ported heads and a small 600-650 cfm carb. His car had a hard time out running stockish 5.0 foxes. People really do build ass backwards engines, so you never know.

While what your saying is true, people do not invest $x,xxx's on their bottom end and then slap stock top end parts back on. That would be absolutely stupid.

You haven't met my brother in law. lol. He'll cobble a motor together out of anything he can find. Your right, people dont intentionally set out to build their motor, paintjob, suspension, etc. wrong but it happens all the time. Sometimes it's just a matter of "oh sh!t" the machine shop work was more expensive than I expected. Guess I'll have to put the old heads on and skimp on the carb & intake.

Yes they do, I've seen people do it. There really are people out there that think that aftermarket aluminum heads don't work right on the street, or that stock heads are so great, or they think that it's nothing but cubes that make power and never take into account everything else. I've absolutely POUNDED guys with 400+ inch big blocks and strokers with my 302, simply because they run a stock headed, no cammed boat anchor. There's no replacement for displacement is mostly true(rpm replaces it but cubes run better and make power more easily) but it's not JUST cubes that make power. Stock 302 heads on a 408 is still gonna make stock 302 power, the only thing stroking does with a stock engine is move the power curve lower into the rpm range, that's all.

That's right! it's more about how much fuel and air you can stuff in the motor instead of just how many cubes you have.

Exactly. Formula 1 cars are a perfect example, 145 cubic inches and they make almost 800hp n/a, they just have to turn 18,000rpm to do it. But it gets the air and fuel in there regardless.
