The wedge will be in higher demand since there are a lot less people running hemis. Although, it'd be nice to have another hemi block on the market.

The iron block would probably sell better due to the lower cost. Even though the aluminum block is better down the road as far as fixing a window or resleeving, most people just base their decision on initial cost.

I went w/ an aluminum KB block b/c it's likely the last block I'll have to buy. If it gets worn out, I can resleeve it. If it blows up, I can have it repaired. Not to mention the machine work was quality and I did not need to massage much at all to use it right out the box.
I bought mine before the World blocks were available. I heard so many horror stories about the old MP mega blocks machining that wound up costing as much as a KB block to make them useable. CHIP

All else the same Al blocks make less HP for whatever reasons, enough of a difference that the weight alone will not compensate for the difference. Given the above I would always pic the AL block anyway due to other advantages.

would you say that the biggest problem with the iron
blocks would be the repairablity?

I would choose AL because of the ability to repair. Even at the higher initial cost sometimes they may be the last block you will ever need. Through a rod through a iron block and it scrap metal.

What i'll be looking at is a Alum or Iron block with a 4.840BS option in the future.

There may be a market yet for a cheap, iron, unskirted(less iron and lighter), dowled 2-bolt main (9/16" stud), low-deck big-block, 4.56" bore (cast them larger), even with a GM bellhousing. Simplify the casting e.g. no fuel pump boss, or internal oil pick-up, etc... Put the feelers out in a thread like this. Or read thru the 440Source proposed block thread archieved in here. If the cost were low enough I'd guess you'll win-over the alloy block people 'cause it ain't cheap to properly repair/resleeve an aluminium block.

why not just use a chevy block, fill in the head bold holes and drill and tap new ones, and use a mopar head? Or just get an Arias

deckheight, bore spacing, rocker oiling, lifter positioning. etc...I don't understand. Are you speaking as a MOPAR purist? Does your racecar have to have an 8 3/4 and a 727?

Im speaking as a manufacturer, I'll make what will sell, but I dont think that there is enough money to justify the cause, or could I be wrong?

Limited market for larger B/S unique combinations...However, there are plentiful supplies of top-ends that can push 800-1000HP especially with a power adder. Something these features should tolerate.

Not you Fred, was talking to BB...much love coming from me to you. It almost sounded like a fecesious response to my idea of intergrading a couple of better features into a proposed item.

Just make an aluminum big block dodge for 1500 bucks and I guarantee you'll be laughing all the way to the bank $$ $$ $$

IMO you already market a HIGH-END block with good quality. How is that one selling for you? Even the B1/PSO and Predator heads are currently built around a 4.8" B/S. A larger B/S block is still a smaller market IMO and this is not the time (economically speaking) to build it assuming others will manufacter/engineer parts compatible. It's been nice chatting but, I gotta go...

"read thru the 440Source proposed block thread archieved in here"

The response for a cheap block was overwhelming.
