Truthful?

Saw this add on ebay and in my opinion the mods he's listed just don't add up to the horsepower he's claiming. Especially on only 10lbs of boost. What do you guys think?

And 42lb injectors. I can't imagine any scenario where 42's would support 750hp. Aren't they usually tapped out around 600?

I think it"could" be legitimate. The engine alone with those heads make 450-500 flywheel hp by itself.

For example I have a 331 with those heads and Im hoping to make 550-600rwhp at 8-10lbsof boost. I have 60lb injectors though. The only thing fishy is the injectors IMO.

Which is why I just can't seem to believe his claim

Your right about the injectors but a 347 with afr 185's and 10lbs would be around 600 I think but he would need 60 lb injectors for sure.

Exactly what I was thinking. Not trying to call the guy a liar but I doubt he's ever run it on a dyno. Seems like he's throwing around wishful numbers in trying to sell the car

I'm pretty sure that is generic and filled in by eBay with use of a template.

Not me, a buddy of mine was gonna shoot him a low ball offer and see what he came back with. I told him to hold off because I thought the numbers were sketchy so I wanted to see what you guys thought.

Probably around 9:1 with 10lbs of boost. I didn't see meth injection listed as a feature.
