As per title. There are obviously unknowns with regards to cost of parts and Libor. But generally speaking which option is cheaper to get done ? Thanks

Or contact Sick Stinger and buy one already complete.
I would go for option # 3.

i modded my 330 to around that hp. if i was to do it again i would have just bought a 502 block and done the same build but been at 540 instead of 489". it also took about a year longer than expected because i was stuck in machine shop jail.

Isn't the 330 454 a 2 bolt block? with a cast crank.

The only thing a 454/330 is good for today is an anchor.
