454worth stroking
 
i have a 79 chris craft excaliber with two 454s. i have the motors out and wanted to stroke them, but my engine builder told me he would only make them 496s. what i was wondering is it worth it for only the little bit of cubes? if anybody else has done this any info would be appreciated. thanks

I guess it depends on how much it'll cost.

You can buy a crate 502 short block for less than 4K.

454s worth stroking
 
he told me around 2300 to 2500 and that was for machining the block and a good forged crank,rods andpistons. i guess iwas just wondering if i would notice a big hp difference? kinda dissipointed i found some nice 540s i was going to buy, but they were tall decks and i only have about a 1/4 inch between my to inner gil manifolds. so they wont fit without a whole lota work.

why not a set or prochargers??? I fthe engeins are in decent shape. freshen them a up a bit for a few hundred bucks and put on a some small blowers. I doubt you wil be able to stroke them for $2500. A decent forged crank alone is at least $600.

excaliber, what hp are your 454's originally. very general increases for stroking a 454 is 50hp and 50 lbs of tourqe. that very roughly figures to be 3-4 mph increase. these are very general quotes and so much depends on cylinder heads, cams, compression ratio. hp generally ranges from 500 to 600 hp.

Excaliber,

Who's got the tall decks for sale? :D

I went through the same thing with my Cigarette. I had 454-440hp cyclones. Not mutch more HP strokeing. Eather way you need crank,rods,pistons. so I sold the 454's and built 540's. If you find the right buyer for your 454's it almost pays for your new blocks and heads. Good Luck :confused: :confused:

Puder,

Where can you buy a "decent" BBC crank for $600???:p

Top of the line BBC cranks cost $1500-1700

Which means "decent" cranks cost around $1000:mad:

well the forged crank that went into my new engine cost about $600 from Bruce Dudley. its a GM 1054 nitrited crank according to the biuld sheet. I sadi i neede d forged crank and to use his best judgement as to wich one. I was expecting the 454 mag crank that was in the engein but due to some hairline cracks it needed to be replaced.

As for other cranks see attached:

both of these are from the Summit Catalog. Perhaps they aren't top of the line but I would be willing to call them decent. And about $600
