"Correctness" is very important to me, with this car. I am not after hp at high rpm. I want my useable power to be in the 3000 - 6000 rpm range. He suggested I go with the Stage one heads, to get the hp at a lower rpm.

If you can find an aluminum Genesis block... you'll find them closer to the "factory look" than the Pond. The big difference is the Pond has slightly "enlarged" external water jackets ( I like the thought of extra cooling capabilities), more so then Genesis and factory 427s. I went with the Pond 482" for several reasons.. Their aluminum blocks are tried n' true, Keith's built many a one and I've yet to hear any negative about the Pond blocks. There have been a lot of rumors about the problems halting production of the Genesis aluminum blocks, enough to instill doubt and convince me to look elsewhere.. The Shelby aluminum is available and somewhat pricier than the other offerings.. It's a personal thing with me; I don't trust Carol or his blocks.. His heads are somewhat contrary when it comes to working in conjunction with other MFR's products too.. I've also heard that Genesis got their aluminum block poop in a group but as far as I'm concerned that jury's still out... time will tell. Which ever block you go with get a reputable, aftermarket FE block knowledgeable, machine shop to prep it properly, i.e. Keith Craft, Precision Pumps, Gess Ford or Barry R.. The one thing they all have in common, none are ready to build out of the box...

I was down to visit Keith and talk about the build for me, last fall. He told me the same about the blocks. He has to machine them after he gets them. I am not going with the aluminum block, though. I want to keep to the "correct" cast block. Does the same things hold true with the cast block? ie. the enlarged water jackets. In reference to the Genesis block, I had heard that Ford discontinued carrying them, because of problems.

So far I have no issues with my personal pair of Genesis blocks - - both have been beaten relentlessly as part of the Engine Masters project. I believe that the Genesis remains your only choice in aftermarket iron at this time - I do not think the iron Pond is available. That noted - the Genesis is the more original appearing of the two from a cosmetic perspective.

Ford Motorsport lists both the iron and aluminum Genesis FE blocks on page
67 of their 2006 catalog. As Barry mentioned, Genesis is the only choice for
iron blocks and as far as I know, the only aftermarket FE blocks that are NHRA
approved for Stock and Super Stock competition.

Okay, good to know. I have to admit the info I had about Ford not carrying the block anymore is kinda dated. I think I heard that last year, someone went to Ford to order a Genesis block and was told they no longer carried it. So you are telling me that the Pond blocks are no longer available now? I had talked to a few people last year and was told that the Genesis block was closer to the original than the Pond block.

Akuminum blocks are available from Pond. I understand he is going to offer an
iron block eventually but I don't believe they're available at the present. Same
thing for SOHC heads although Robert was reported to say that he had no
immediate plans to produce those.
