Has anyone bought a World 427 street alum head crate engine and installed into 1st gen camaro-firebird? Im thinking abought it. (cost is $9,000.00 ) Not bad for 530hp + dyno tested.

I thought it would be really cool to do one of those too and had considered it for a long time, but i dunno... the cylinder wall is pretty thin at that point and that might cause issues with wall flex.

I have one in my '69. I bought it as a shortblock and built the rest to my preference. They do make good n/a power.

My friend ordered a catalog from them, was interested in that engine. The pages with that engine were torn out of the catalog!
I don't know why...

They also have a 2yr/24,000mi warranty with them. I too considered one, but they won't customize their turn-key engines.

I had looked at them too, but the price seems kind of high to me. Granted it has a warranty and dyno proven etc, but it seems to me that I could piece it together for alot cheaper than that....

Block $2000
Heads $1800
Rotating assembly $1800

That leaves in the neighborhood of $5000 for misc.....

Who is the Mailman & is he happy with it. I will have a 427 mouse from B.M. or do it up here in New Zealand (the shipping is a killer).
clinz28 you got picks? dyno tested?

Scott Sharioff is building some bad Hombre's also. The throw between the 5000 and 10000 looks long until you get pencil screwed to death on all the little things it takes to make a motor run. Not to mention weather or not one really has the ability to build such a thing.

The 427's have a 4.125" bore--the same bore that was offered on OE 400 blocks for years. The Motown block is a much more substantial design. Plenty of meat left since the Motown blocks will actually go to 4.250" (They stopped publishing that fact). In fact, you may have that engine forever since you can keep cleaning up the cylinders in .030" increments if and when you do wear it out. They claim .250" wall thickness at 4.200"

At 4.250" things are getting a little "thin in the skin". Looks like they stopped offering 454's.

The warranty is the real deal, too. Blow the sucker up and the insurance company covers the loss.

And unlike the GM crate engines, these engines are filled with brand name parts, dyno tested and warranteed. It's not impossible, but you'd be hard pressed to duplicate the results for the money.

here's a copy of the dyno sheet
