Horsepower Estimate?

The magazines create unrealistic expectation. An xe268 will likely be a high side of 1.1hp/ci stick in an oem style/stock headed 340-360 with a great tune up.

If I told you Billy Barty was 7 feet tall and had a tape out (dyno) that showed he was 7 feet tall, would that be ok? What if you met him and he was really 3ft 9in. Just because it's the data you see or read doesn't make it valid, nor supportable when other data shows the build is way off base.

That's all the info most people have access to, millions upon millions only knows those numbers, majority becomes the standard, officially or unofficially. If your 7 feet was equal to my 3.9 feet we can convert for that. So if a magazine 390 hp equals your 360 hp we can convert for that. All I'm say most don't have access or knowledge of your dyno numbers better or not they ain't the one most are gonna go by.

I've said it many times, built a couple 360's with a xe268, rpm/ld, 750dp, dougs/tti/5204's and good OEM heads (equivalent to the dyno derby pieces) and NONE of them made more than 360hp. NOT ONE.

I'm not arguing they don't, I would agree that that sounds like an reasonable number for that combo.
I don't think of a xe268h cam as anything more.

I'm not going to engage in this with you, carry on if you like.

Selling parts is job one for them.

Yes magazine and such obviously rely on the aftermarket, there glorified ad's for the most part.
