Thoughts on doing some 454, 330 upgrades?

I can spend about $1500 per engine and don’t mind used parts. Please understand that 1500 is the number I want to stay below and going 100mph is not what I am looking for and yes I understand these are not performance engines. I am talking good Chevy stock heads, cam, intake and carb or something like that.

Please be considerate and understand that 1500 per side and 3000 total is a lot of money to me and I would appreciate not being trashed for not spending more.
Thank you!

Here is a great example of a budget 454/330 build........ but at a $1500 a side budget...... Set that money aside for normal maintenance. On a twin engine boat 3k in maintenance in one year would still be a win in my book.

I would save the $$ until a year or 2 from now and you can make it $6,000 and upgrade power. The 330's are really nothing to bother with. They can handle 400 hp but why bother spending a lot of money on that? Please understand $3,000 is a good chunk of change to me as well. Save the money, sell 2 stock 330's and buy 2 420's or hp500's.

i agree 100%.

What year 330's and what boat are they in.

Thank you, I actually take that as a compliment!

+1 on that....... even a set of used 502 mags would really wake things up and be a great foundation for later upgrades

the problem with the 330s is they have cast cranks and pistons and the small 3/8 rod bolts and the peanut port heads.if you sold them and bought some 365 mag engines you would have a solid setup to build on,forged crank&rods and the better rods with the 7/16 bolts and the rectangle port heads.500 hp is easily gotten without spending a lot of money and you dont need to wonder if it will break the crank every time you run it hard.

1+ To everyone that posted already. Run the boat for a few more seasons and save up some more money for better engines.

your welcome,it looks to me like you and i are on the same page.
