SB Road Racing/Nascar/Sprint Car/Reving BUDGET BUILD

I have built afew circle track magnums, a 400 hp, 6300-6400 rpm 5.9 can be built pratty cheap. Valve springs are a must and the ones I built would bend pushrods at them rpm’s, Hughes has some that work well.
Could it be turned more In this type of build? I dont know, I was comfortable with these rpm and never hurt anything.
The motors I built that were larger (rpm-hp) had better parts. If you want to finish first you must first finish.
I am really amazed with the 5.9’s I’ve thrown some really cheap **** together and honestly didn’t think it would live 1 night and they always healed up well, good luck !!!!!!
1 more thing, Hughes has some really good articles about installing cams, making sure lifters rotate and such, he has a couple paragraphs about oiling and iirc it is in the stroker section, not his oiling section, kind of hard to find.
I know a lot of people have bad experiences with Dave but he really helped me out a lot on what works and what doesn’t!
