Saw it at PRI. That product would have been cool 10 years ago. I don't get the point now.

i know, considering i sold everything SBC related just to afford my LS engine. it would have been nice to use my MSD billet dist, 6al box, and march billet serpentine pulleys!

oh well. wonder if the block is going to cost a couple grand.

i take it headers will still be a pain in the ass to fit in any chassis with that set up!

An I wonder if LSx swap headers will even work with this combination.

nice tech....

What is the benefit of using an old school block? Just being able to keep all your current serpentine and ignition stuff?

V8Rumble · 12-17-2008, 09:40 AM

Maybe that, & the fact that I could "upgrade" from my current 6-bolt main block to one with 4-, or even 2-bolt mains - man, that's weight saved from the front of the car!!

OK, being serious now, I'm with Andrew - I really don't see the point, except for some very limited/specific applications...

But it's a mildly-cool engineering exercise, I guess.

I'm w/ you guys also (Andrew, TK, and Lucky).

Why would you want to bolt modern heads to an old school block?

I see the whole keeping accessory drive and everything, but I gotta think the cost of this custom block would ruin the practicality of that idea.

It is time to let the SBC rest. Lets face it... it is now what the flathead was when the SBC came out.

Can't you just buy some AFR's for your SBC? Cool, but mostly useless in this market. You can prob buy a full LSx pullout for the price of the block.

v8bug · 12-17-2008, 10:59 AM

my bet is the only people who will buy these are serious roundy round racers who are pigeonholed in using old style blocks

luckyhenriksen · 12-17-2008, 12:59 PM

Or somehow limited to what type of block they use by the sanctioning body they race in?

DCx · 12-17-2008, 01:05 PM

I would rather build a nascar SB2. those heads flow!

Qwiknotch · 12-17-2008, 03:39 PM

I see the point. No more factory style shitty LS oil pumps that self destruct over 7800rpm. Now you can build a 9000rpm LS engine without a dry sump or external oil pump. The 4 bolt splayed caps are far superior to any factory ls block, except for the LSX block.
Even with the 6 bolt mains, they are notorious for walking unlesss you get them pinned or put the billet caps and main girdle.

I know I am seriously worried about my oil pump coming apart, but I can't run a dry sump or external oil pump in the class I am running.

Thank you. You guys should read the article in this months hotrod. It works like this, it is a specific block that is designed to use the lower end from the SBC. You can use the crank, the rods, oil pump, pan, frot cover/accessories.

Mowtown used the combo and actually had it push more power than the SBC or the mohawk LS engine from the same company.

BillMitchell actually sell it as a crate motor 427 cubes, 800 hp N/A.

luckyhenriksen · 12-17-2008, 04:56 PM

Well that makes it cool

Oh geez... Generally speaking, magazines are NOT a good source of information - they're in business to sell advertisements, and being critical of an advertiser's/vendor's new product isn't exactly a great way to sell more ad space. Publishing articles is just the way that they get us to pick up (& hopefully buy) the magazine so that we can run our eyeballs over the vendors' ads (preferably more than once)...

And just for the record, I glanced over the article the other day, when my copy arrived in the mail. I'm still not particularly impressed - (IMO) the benefit provided for the probable cost just isn't there.

(This is the same magazine that had the feature article about the Mustang that some idiot spent $1,300,000.00 on, & yet it still wouldn't make one full-speed lap around the track, right?)

Just my 2c...

I think it's a good idea, but it is a little late to the game. Definitely opens up a lot of options when putting together an engine. Someone with a SBC in say 3rd gen could easily swap parts and buy a set of LSx heads used and see substantial gains.

Qwiknotch · 12-17-2008, 08:09 PM

I know it will combat my problem of having to machine the crap out of my LS2 or LSX block to put a belt drive on it.

luckyhenriksen · 12-17-2008, 09:18 PM

Do Gen III heads/intake really flow that much better than a nice set of alum. heads for an original SBC? If your going to lay down the coin to buy a new block, wouldn't you just keep going and buy a nice set of ported heads for a Gen I?
