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.

Probaly buy one already done up. x2 on Sick Stinger, he always has parts and motors etc for sale so i would go with him. Thats what I will be doing.

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

I believe there 4 bolt, but do have cast crank and small rod bolts.

from what i understand its just luck of the draw. my 88 330 was a four bolt main, "high perf" block.

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

Had one myself. Sold it and bought a 502 for the last boat.
