Bit of extra capacity for the 2 but I think it's got a weaker block, inferior water pump, poorer internal cooling and GM have been saving a few pennies with the LS2.

Personally I prefer the 1 or 6.

I dont think there's much odds between the 2.

The LS1/6 has extremely thin liners, whereas I think the LS2's have thicker ones. Overall block may be stronger, but unless you intend pushing 8/900+ I dont think its an issue to worry about.
It seems to be easier to take the LS2 to a 4" bore than it is an LS1/6, which would be a big advantage if you want extra capacity.

What I would like to do is run an Holden Crewman SS8 on LPG.
I'm going to do 500m+ a week so I believe it would be a good investment

take a look on LS1-tech.com. some really good advise and info!

a engine shop recently took apart a LS7. they also had a LS2 in their shop. they said that apart from the thinner (and weaker!!!!!) liners of the 7,the two blocks looked identical!!!!!

as for strength og the block, i dont think you will have any problems! i have only heard good stuff about the LS2. APS is pushing over 650bhp from a bone stock engine (not even opened yet!!!). and if you want big power, then W2W can build you a forged short ot long block that can handle upto 1250bhp!!!

personal i think for road use the is little diffrence between the two! the LS2 is a little more pricy, but you can get similar power from the LS1 with a cam and some headers!

thanks Chris.

PS, builder how much is one of your 427 ci LS1 short blocks?????
