LS1 block or LT1 block?

[BLLDOGG]

well i have an offer from a junkyard to buy either of the blocks. and thats all im getting. he has already taken them apart to sell the parts. anyways, which do you guys think i should buy? I'm going to build the engine up w/ the best parts i can and have it setup for forced induction. i want it to be a very powerful motor and strong enough to handle it. i have always heard the iron block of the LT1 was really strong. i dont know anything yet as for parts anyways but i'll do my homework. i just want to know what do you guys think would be the best block for high power drag racing. im just so glad im getting either one. i has been a long awaiting dream to start building my own v8 from the ground up.

LS-1... and you really don't need FI to build a powerful LS-1 either... ;)

Cast iron block LT1 will handle the power better than the aluminum LS1 block.
LT1 will be cheaper to build up too, I think.

Lots of new stuff coming out for the LS1 though that make those things run pretty wicked... I'd probably go for the LS1.

[BLLDOGG]

i'll get the LS1 then. well, i want forced induction cause i really am a drag racing inthuseist and i am going to be a drag racer when im done with my education. so if i cant be a driver then im ganna want a fast car still. and when i say fast, my goal will be, well, we'll just see how fast she goes in the end ;)

[BLLDOGG]

can you guys give me some tips on keeping the block in good condition till i start building it? i dont want it to rust

EDIT: 95batmobile, you have mail.

LT1... just because of the sleeved LS1 block though

[BLLDOGG]

what do you mean sleeved? can you explain that to me?

[95Batmobile]

RallyRed they are putting a new type of sleeve in them that actually holds up pretty well... I can't remember if they're cast iron or something else.

these 2 blocks cost the same?

[ellik]

go to www.nu-tekmotorsports.com to get a good idea of a forced indution LT1. Personally, I would go that route.... but expect about 8 grand in the engine for the best parts. Fully forged and stroked LT1 bottom end with a LT4 conversion top end with heads from AFR.

[BLLDOGG]

o' im going to go all out on this. it will probably take about 2-3 years to do the engine not including having the forced induction. i will have my car payed off by then.

Good plan... keep with it and you will enjoy it [img]graemlins/rock.gif[/img]

The early LS1 blocks had a very thin sleeve. You couldn't bore it out, and resleeving is expensive. The later LS1 blocks had a thicker sleeve designed to be bored out so the engine could be rebuilt. Not sure of the exact year, I believe it was 2000+.

What are you going to do for induction? Piecing together a fuel injection system is going to nickel and dime you to death. LT1 with a direct ignition system would probably be your best bet. If you going to go LS1, buy a complete motor, not a block.

[BLLDOGG]

well it a 2000 block, but he isnt offering the whole engine cause he has already stripped it and even sold some parts. as for forced induction, im not really sure. im a supercharger man and since its going to be a trailered drag car, a blower would be nice but i have no clue if they even have one that would go on an LS1. as you can tell, i dont really know much about what im getting into but im really intelligent when it comes to this sort of thing and it wont take long to learn what i what to know when i actually start to research. keep the info comeing. if it even matters, this is going in my camaro when its all said and done.

BLLDOGG you can get 400+ cubic inches out of the 6.0L block, PLUS its cast iron... you can make a beast out of those things.
On top of that, AFRs new badass heads for the LS1 work on the 6.0L too... I might build one after I graudate college and start working... or I might build a real custom 3.4 just to play around with [img]smile.gif[/img] havn't decided yet.

If you are serious about it, I can talk to my dad. He's been a mechanic for 30 years, his specialty is building motors..
