This guy wants to sell me a 454, bored 30 over, and something about racing pistions is all i heard him say, i dont know much more than that, he said it makes 450hp, and alot of torque lol.........it was on an Airboat is any of you know what that is.......he wants to sell it to me for $5,000, do u think its a good deal?

in my opinion...no. Without more details, definitely no.

From what I read, and I'm sure most Rat-lovers will agree...making 450 from a BBC is not a difficult task.

With the mildest of upgrades you should be able to get 450 from a BBC easy. Dump a few dollars into a big chevy and you can get 600 ponies or better.

Too much money for a motor you know nothing about... I'll have about half of that into my 454 build...

Get casting numbers & any other ID info from the engine, then post here or run them at www.mortec.com , otherwise you may end up with a tall-deck 366 that was being used for an anchor.

ya, when i get home......ill see what kinda stuff is on it, im at work now hehe, ummm so u think a 454 isent worth $5,000.....or do u think i could get a better motor for that

a semi-built 454 might be worth $5000...but then you still need to ask yourself what kind of condition is it in...better yet, why is the guy selling it?

I bought a running truck w/ 454, good body (even though I didn't buy it for the body) for $1200. I didn't know when I purchased it, but the head castings are good 353049/113CC open. The block was manufactured for Marine useage...from the factory the thing made 310 HP, not too shabby.

With a minimal investment, maybe $2000 I hope to push it up around 400-450 range.

For $5000, you could probably buy an old beat up camaro with a mean big block in it.

its Brand New everything on it is new, he bought it to go on his airboat and then drove it id say for about 30-40 hours and then stopped, hes building a 572 engine to go on his airboat now and doesent need the 454 anymore, but im going to findout today what all is on it

I just bought an engine out of a 1980 gmc truck for $300. I have to do the work myself, but after $600 at the machine shop I have a hotdipped magnafluxed block bored to my specs. I dropped off the cast heads complete and picked 'em up ported with 205 valves ready to bolt on. I bought a set of slightly used forged pistons with connecting rods on ebay for $100, a rebuilt holley dbl pumper 750 (polished) for $70. An extra $1500 on assorted crap from jegs and I should have an equivalant engine for half the price. oh yeah the machine shop also balanced the stock crank and my new pistons.
Good Luck, Robert
PS for referance a new stock 454 from gm produces 425HP @ 5250 RPM W/500 ft. lbs @3250 Rpm
sticker price from jegs $4899 (you need a carb)
