Rebuild or crate???
The block is a late 89 truck 454 with a vette 396/427 steel crank and original 427 worn cam. Internal components put it at 427 ci.
After pulling the original iron 427 heads I see that the pistons were bored .060 thousands over putting the displacement over 427. I need to replace all internals...crank, cam, lifters, pistons ect. Will need to replace valves, valve job, springs ect. Will need new intake, waterpump, oil pump, distributor and all bolts and gaskets.
Would it be cheaper and more benneficial to just get a crate engine?? and leave this block for my slow forged twin turbo project to be ready in 20 yrs and have fun with the crate??
Any good deals out there on a big block crate? Would like over 400hp.
D&J Machine & Performance Engines on ebay seem like they make a good deal 454 with 500hp for a decent price. Any feedback from you guys?
I can take a decent hit on my bank but would like to keep the budget under 5k if I can.
Any opinions? rebuild or crate?
Any good deals, need to make a decision very soon before I send my current block to the machine shop.
Thanks

I also live in NJ and had previously purchased a "crate" engine on ebay from a builder in arizona. I thought I was getting a good deal. My car has spent more time in the shop than on the road. The motor was NFG. I had a hard time resolving the issue because of the distances involved. Stay close to home. If you want a local ebay seller, look up Victory engines, they are in the NJ - PA. area and their long blocks start $$$ below anything else on ebay. I have no personal experience with them, but if something should go wrong, they are nearby and you would be able to follow up more easily.

Suggestion...get a 502 bare block and use your 3.76" stroke crank, big bore, short stroke, will make a hell of a screamer. That said, you can use your existing rods and JE makes pistons for this stroke, bore combo.
It's like buying shoes in a catalogue. The picture was really nice but when I got them they didnt fit....

I am happy with my crate motor. I have put over 15,000 miles on it so far.
Just looking for the best bang for my buck...
Where's the best place to look for bare blocks, engine parts, cranks, cams ect? Looking for a company that stands behind their product and doesn't make me sell my body to pay for parts. Although that could be fun.
Any brands worth recommending? Scat? Summit brand any good?
Any engine shops worth looking into around Jersey that you can personally vouch for? looking for advice in planning the rebuild and machining.
Appreciate the advice. This is my first engine rebuild on my own.
I'll buy you all some beers the first time it gets on the road...gotta get'r done...I'm thirsty





i agree how can you go wrong with GM crate motor....all the engineering is done by people who actually have to stand by the product and offer a warranty.....and its designed by engineers

GM built and warrantied.
Guaranteed reliability. Not a shady eBay'er or possibly crooked machine shop.

I'm located in northern jersey near Montclair and Newark.
Those Motown blocks are really nice, especially the 454 with the improved cooling flow...but I don't have the funds for that type of build-up at the moment.
Still inbetween build-up or crate.
Even though my heads are original 68 427 heads with todays technology they're probably going to be my weekest link if I do a build up and will be the most expensive parts. Just trying to figure out if parting it together will be more expesive then just a crate.
Anyone know what those zz454 GM crates go for? no listing on the GM website. They're all forged which is perfect with low compression but I'm afraid to see the price.
$25 would be nice.
