Ok, twin turbo big block.......:thumbsup:

I almost started wavering back to the Old School SBC after see the new short block DART is selling with thier SHP blocks. Then I ran the numbers again and I am back to the LS. Which really stinks cause I like the underdog..

The Dart SHP block is a great foundation. But as good as it is, the newer technology behind the LS series with thier efficiency, durability and ease of making more HP is really hard to beat. If I was not going BBC I'd be doing an LS motor. I have always wanted a big block and now is my chance to do one right. Next project will be an LS for sure though. The prices just keep falling too, bonus!
I say to each his own. Any one of the three can make good power and be a ton of fun. They all have thier place in the hobby.:cheers:

X2 well said. Additioannly I am seeing more and more Alum block avail for GEN big and small block. Even on the used market. If the Super mods and other classes move to LS platforms we could see the market fall out of Gen1 stuff.
Like Alum SBC 18 Degree.. on the cheap.. I am all over it]
I constantly troll RacingJunk.com for deals

I agree. There is alot of good stuff getting cheaper by the day for the old platforms. It was not too long ago that you could not touch a set of BBC aluminum aftermarket heads for under 3k. Now they are everywhere. But the LS stuff is following suit. It is all coming down with time. By the time I am ready to do another project the LS engines will be very affordable. They are not too bad now.

Good thing for us huh Eric???:cheers:
lol:thumbsup:

Yes it is. If the clock were turned back 5-10 years on BBC pricing for cool aftermarket stuff there is no way I could build this the way I am now.
But then again, naturally aspirated small blocks pumping out 550 plus hp were REALLY rare and VERY expensive. It's like anything else, time and competition in the market place bring prices down. Look what a new microwave cost when they first came out in the '70's to the mass market. VCRs, DVD players, CD players for our cars. Can you imagine paying close to $100.00 for a Sony Walkman? (That's with a TAPE player inside LOL). I am old enough to remember asking my parents for one and them saying something along the lines of "when hell freezes over" !:lol:
So now we have top quality parts available at prices that allow guys like me (on a budget) to go play with the big boys. To come to the party with a respectable level of power and reliability and on pump gas to boot!
I do believe the small and big blocks will always be around, but the LS is going to take full charge of the Chevy power end of the hobby. It is just a better mouse trap (no pun intended).:thumbsup:

I will stick with my set of GMPP 18 degree head set up, massaged over and flowing more than 325 cfm. Mated to a nice SHP block or little M 427-454. Just have to crunch the numbers on everything to make the best selection. Lookin at about 671 hp with current cam and 11:1 compression. But I'm gonna go with a smaller more tame cam and about the same comp. so in the ballpark of 600hp.

Do what makes you happy. and a mean muscle car idle makes me happy :hail:

If you include the possibility of an aluminum version of the LSx (probably NA only and possibly in restricted displacement), I would choose that.

Of the traditional SBCs, I'll keep my EFI 4-bolt 350 with AFR heads. I could see doing a 400 block with a 350 crank and keeping the good stuff that I already have, but going no bigger inside.

I don't particularly care for long stroke geometry or forced induction. I'll just look for a smaller car to put it in instead.

LSX all the way. It is popular to people on these web sites but overall you will still won't see that many. Just too good of a platform to start with.
