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

I say you start with a magnum 360 instead of an LA318 and choke it down with terrible flowing 273 heads. You said you wanted to go cheap then, instead of building a bottom end you could mill the heads to get more compression and throw a cam in it and go!! CHEAP!!
Correct, I did say this. Also, looking for something that will have a good high RPM limit in the end. So whatever engine I start with, it would be good for it to have a good ending point without having to switch blocks in order to make the power or RPM's.
