Who builds reliable race/street engines?

That kind of power should be well under 7k. I have no experience with blueprint so I’m not going to talk about them but you shouldn’t need a crate motor to make that kind of power.

I may have underrated the horsepower I was looking for. More like 350-420. Crate motors seem to cost less in the mong run, than building what I have. Even the ex-owner of my car recommended not opening that can of worms, since that 318 I have now, he dropped in stock from a 72 Demon with 60K miles. And that was 10 years ago. The ex owner and current mechanic recommend a crate motor for less issues in the long run, not to mention continued dump of money in a possible crap motor that doesnt sound so healthy.
