Genesis block


I am currently considering imorting one of these repro Genesis Aluminium 427 blocks for a -63 Galaxie lightweight project i am about to start working on.

But since the block and parts will cost some serious cash (not to mention the shipping to Denmark and importtax) i would like to know if anyone here has any experience with these blocks??

is it a quality product??, can they take a heavy right foots abuse??
Are there any other manufactures over there??

Any input would be great

Re: Genesis block

Both the Genesis and Pond blocks require some good machine work before assy. There are a few quirks and area's on each that require attention. I have a iron Genesis block and I bought it from Keith Craft. Keith knows his way around these blocks well. It's well worth the extra $500 to have the block work done before it's shipped. This is something you can save a few hundred bucks by using another vendor but can cost you much more in time and money to repair elsewhere also risking the chance of the block not being machined right. On the Genesis blocks here's a quick rundown of things.

Cam tunnel align hone and cam bearings installed.

Head decks slotted to match factory oil holes in heads. On this oil feed holes are not in the factory position and without the slot no oil will get to the heads/rockers.

Finish bore and hone cyls and hone lifter bores

Thrust bearing maincap chamfer. Without this checked and clearanced if needed the thrust bearing can fold into itself and cause the crank to bind.

#1 cam bearing clearanced for distributor. Bearing needs to be notched for the distributor to drop in.

#2 and 4 cam journals opened up to .050" to match oil passages. Factory and aftermarket cams grooves are .025" wide and need to be widened to be sure oil will pass throught to feed the heads.

It's nice to see these aftermarket blocks. But like any block everything needs to be checked well and gone through.

Hope this helps answer a few things....
