"Blown"

[oledawg]

OK, my boat tech is telling me that I have "holed" my 454 which really doesn't surprise me as I am the 3rd owner and lord knows how it was treated before I got it. All the last owner said was that it had less than a 1,000 hours on it ;-)

So, I am now in the decision process on what I need to do to get it running again over the winter. I don't have a "show" boat, just one that I truly enjoy driving, so I am not looking for mega HP....given the way my engine was built it supposedly had something over 400 hp...would run about 68 to 70 gps. New block, etc. and rebuild "might" be the best option unless someone out there has a Big Block ready to go for a reasonable price.

Thoughts?

Get a crate marine 502. 400hp out of the box plus a great base to build on if you want.

usengines.com offers a long block 454 rated at 420 hp for $2995. Anyone with experience with these folks?

Purchased my short block shown here:

More expensive, but with new 4340 crank and rods, plus other stuff.

It seems like they have every combo you can imagine.

I am happy with the build I received from them.

A lot of options out there.

Good luck.

just a thought, not sure if you are interested, but you can go down to a small block... merc has a 383 Mag @ 350 HP, drop in, turn key, MPI, even comes with exhaust, for under $8k. Performance wise you'd be the same but you would have a 3 year warranty and all new accessories.

by the time you are done buying a long block, paying the mechanic to swap everything over, etc. you may not be far off price wise.

383 on eBay

My ole engine had probably at least a 1,000 HARD hours on it before it gave up the ghost, so I am a believer in Big Blocks, you can run the heck out of them for extended periods without worrying too much. The small blocks can give you as much or more HP but not so sure about life spans at WOT. With a 420 HP 454 at $2,995 and probably no more than 20 hours of tech time to swap out the external parts, etc. I should be in a "new" engine for between $5,000 to $6,000 unless I am missing something. That is why I am asking for input on the forum, I am sure that there are folks that have been right where I am

used engine?? you dont know what you have.... call eagle engines "new'' only.you can get this one for around 6k swap your parts but you will need a bigger carb and if your fuel pump is not on the seapump then you will need to install a electric one then go boating..

I have an Edelbrock intake and an 850 double pumper Holley on it now that should work no matter what engine I come up with I think. My boat guy is trying to put me in a Jasper 420 hp for $7,000 plus labor....seems awfully high to me, but again, I am not the tech

you can buy a BRAND NEW GM crate 454-425 for just over 5k, thats what I have, it's been ridiculously reliable for 6 1/2 years now

Dumb question, but where do you get such a beast and what is included with "crate"? Is it marine?

[mrfixxall]

this guy is asking 9k for the pair,,you could see if he would split them up and they have gil exhaust anf other assories to...

New, not rebuilt. Pretty good deal. Bolt and go.

Check with Harbormaster. He is selling the GM stuff.
