.it just sounds like a 400hp build, not a 500hp build.

now that's more believable

"500HP" is a very common number people grab out of the air to simply mean a really powerful engine. It could be that's what he was doing.

I would be quite ticked off if the engine fell short and I got an explanation that it was a figure of speech. But yes, that is a common figure of speech. It's easy to tell the guys who are making it up too. Very few builds make exactly 500hp! So the guy who tells you my engine makes 508hp is more likely telling the truth.

With good machining and assembly, enough rpm, and the right cam it can make that figure with 250cfm heads. It's not "head limited". But you still have to Stage III port them and match the intake, buy good valvetrain parts, and fully machine the block, etc etc etc. That's why I say if he's earning a living doing this I find it hard to believe for that money. 400hp is easy for $4500. 500hp is another $1500-$2K and I still think that's getting out cheap.

And good luck with the stage III porting. I had a set of 906's done using the MPP templates. They leaked in 5/8 cylinders and cost me about 1200 total when it was all sadi and done.... For a stock set of iron heaads. Awsome. Lesson learned.
