Aluminum 427 Small Block Gen I

[nitrorocket]

You can buy a used LS1 aluminum block for $200.

Have you thought about LS1-2 motors for your "street" car?? Same power, 1/4 the cost. Just an option??

Where?!
I just bought an iron LS1 block for $75. I would have jumped all over the aluminum one for $200. Lowest I have seen is for $500 and that was for a 5.3.

The best place are

Donovan
Brodix
Dart


I haven't used a Brodix block yet,put I use alot of there heads,and I have never seen any junk.

I have seen boat loads of bare ls1 bare blocks sell for the $200 range in the last couple years. This one below had much more with it. You can buy complete turn key motors with a trans for less then a Dart block, that's not bad for a block good to well beyond 1000 hp!!

World makes an aluminum LS series block called the Warhawk that accepts a 4.125" bore and costs less than the Gen I blocks. About $2K - $2500

Sorry, I confused the World aluminum block w/ GMPP's iron block. The World Block is $4K. Forget I was here.

If World products didn't make that Warlock I think it would be great,but I have seen to much WP junk.


I,m waiting on the new GMPP LSX steel block it will go to 511 inches,

Really an aluminum block on the street isn't needed,It's cool to say it's all aluminum,but a steel block will be useless.

If you were doing a BBC an aluminum block on the street would be worth to drop a 150 pds.

If you go the LSX route,a LS2 is the way to go, the casting are better than the LS1 block

An aluminum block can also be repaired, that is one big advantage!!

Yeah,maybe,many can't be saved,but if it's a street only car it shouldn't be blown up that bad.

LS1 blocks are bad about be junk when they blow up hard.i have only seen one or 2 be fixed when I sent them off

6 of 1, 1/2 dozen of another.

This type of talk doesn't flatter the aluminum block at all.
