why not just sell your 383 complete and then buy the 427 or 454?

You're going to spend more in the long run that way. But hey if you want less for more then go right ahead.

Yeah, it takes alot of air to feed a 454, but that F1 can do it

The short block might cost 7000. you could probably sell your motor for 3500 or so. If you were to reuse your stock parts you would be limited to around a 427 or 440. Plus you would still have the price of the block (2100) plus pistons and rings (800) and fasteners (250 or so) plus machining (750 or so).

And if you were to go with a built shortblock you would have a warranty on all the components from the company that sold you the shortblock vs. having warranty from one company for machine work, one for pistons, one for rods, etc etc. See how it all adds up now?

There's only two shops that I know of in this country that will warranty a "forced induction" engine........NRE and LPE. LPE rips people off and charges 2-3 times what the set-up is worth, so in essence you already pay for a couple set-ups. NRE doesn't charge any more than the set-up is worth, but they build solid set-ups so they can offer a warranty on a 1,850 hp TT 427 and a 2,300 hp TT 454 LSX blocked engine.

If 1,000 hp is all you want, a World block is complete waste of cash. Any LSx block will do. If you want to have gobbs of reliablity and longevity, use the GM LSX iron block, its the king. $1,995.00 is cheap for that bad boy.

We finish a procharged LSX block build in a WS6 with a couple weeks ago, everythng bolted up nicely.

What your going to find out using old parts, Unless their Lunati or Oliver rods they may not be worthwhile refurbishing, we had a set of compstar rods rebuilt with new callies spec ARP 2000 bolts and for a couple extra dollars could have had brand new CompStar H beams.

Chinese made, I wouldn't want that in a 1,000 hp set-up. There have been failures of Eagle cranks, I've never heard of the top American made cranks breaking. And, yes, some cranks sold by other American companies are macde in China as well, but not the top of the line cranks.

Katech had a stockpile of Cola cranks they were selling off, see if they still have one. Probably the best crank ever made.

Maybe Eagle is better now????????????

FYI ive made over 1100rwhp with Eagle rods and a stock crank...
The stock crank was starting to flex at those power levels...
There is nothing wrong with using eagle parts to make big power... they have proved they can do it over and over again...

An LSX Block is a waste of cash if your not going to go with 6 Bolt heads.
Thats the whole point of going with it... more clamping force.
Now the $1995 for the LSX block is cheap but around $3500 for the 6 Bolt ETP heads isnt....
The World set-up is $4.5k for the block and $2364 for the heads.

LOTS of misinformation in this post. The eagle stuff is fine at 1000hp.
