It’s been a while since I’ve posted anything on here. In fact, the last thread I had going was very similar, but life took over (baby) and so I had to put it off. Now I’m getting the itch again after having saved up some money. My coworker has a 400 from a truck sitting in his backyard he’d be willing to sell. He also has a 327, and I’m tempted to build a 8000+ rpm motor out of it.
Last time, I had my mind set on just going with a Blueprint 400 sec and calling it good. Now, in late 2022, they seem to cost a couple thousand more than they did a few years ago. This also makes me believe machining costs have gone way up, so finding my own 400 and building it myself, like I want to do, will be just as, if not more expensive. Both of these factors make the higher cost of doing a complete LS3 swap seem not so high any more.
Anyone have any sage advice? Take these points into consideration (I want, at least, 2 out of the 3):
1.) I’ve never built and engine, and I REALLY want to take this opportunity to make that happen.
2.) I’m saving up to buy a home… in 2022… in California, so budget-friendly is a huge factor.
3.) I want to reliably make 450-550 hp, capable of 7000 rpm, and plan to use it mostly for autocross, but still want streetability.
