415HP from 318ci IS POSSABLE!!

But he has a $2,500.00 limit, and your cost is nearly double what he has to spend. Not saying that your combo wouldn't do it but there are cheaper ways to get the same results. Already been there done that, even if I charged him for a complete engine I personally don't see more than about $3,500.00 for the engine. If he wants I would sell him the engine that I have for that and it makes way more power than what hes looking for. And it's not a stroker it's a 318. But this is my personal opinion.

I didnt mention a longer stroke. I specificaly stayed off that path. I don't see you being able to do what he's asking for that figure, using the parts you've outlined. Not that much flywheel hp. Not using the pistons or heads you suggest. Not with him doing the porting. Not with skimping on the few operations that make or break a build. I said I could do a stock longblock with a cam for that, but there's now way in hell it will make 425hp. 325, sure. Pretty easy. But thats where the cheap stops and better parts have to be used plus more labor costs become mandatory. That was my point. Now as far as machining costs... I'm in CT and I have to pay CT performance shop labor costs too. God knows we aren't called the most expensive state in the Union for nothing. It's nice to hear all these ideas and no disrespect intended. But I dont see the numbers as provided adding up. Not for what he needs, and not with what he has to spend. I would say do it, account for every nut and bolt, and stick it on a dyno to see if it works. I dont think you can do it.
