Hello everyone I'm new here just registered a few moments ago have alot to ask and alot to learn so for my first post might be a little long. In a few weeks around the 27th I'm picking up a LS1 block my plans for the motor is straight line racing would like to get around 700-800 HP and in the future adding either nos or turbos, I'm planning the build out before I get out the plastic to pay for parts. I figured I would start the build by getting the block checked and bored then work my way up from the crank to heads. Now I could be wrong on this so please by all means correct me but for the fasteners I would like to get titanium bolts due to high tensile strength I have been hearing that stock fasteners can hold up to 450 HP. For rods and crank I wanna get forged parts along with roller lifters, and I heard about a bearing known as a dirty bearing? There for the crankshaft where can I find these "dirty bearings"? Any suggestions will be taken seriously as iam not sure what brands of parts to go with and stay away from.

thanks for any advice in advance

 

Welcome to the site, there's a wealth of information here so look around a lot and you'll l LS engines haveearn a lot.
You say you're getting an LS1 block, I'm guessing you mean a 5.7 aluminum block. If so, maximum overbore will be .010, so be aware of that.
I haven't heard of titanium fasteners for LS1s but ARP brand fasteners are surely good for the horsepower you are looking to have.
With NOS or turbo you are wise to go with a forged rotating assembly for durability.

 

LS1 is probably the worst starting engine for boost.

Get a late Gen 3 truck engine. A bone stock long block will hold 700-800 HP no problem and they're half the price (or less) of an LS1.

 

Welcome to the forum!
From the verbiage you're using, you either have experience with old school engines, or you're talking to people who are. That was me a couple of years ago before I messed with an LS engine. I am going to make a suggestion. Read. Read. Read. Don't buy anything until you spend hours upon hours reading through the many build threads on this site. Read all of the engine sticky and then start asking pointed questions. There are many unique features to the LS motors that, as old school motors guys, you will have to change the way you are thinking when it comes to the LS motor. The days of .30-.60 over-bore is over with!


Welcome again to the LS world. Do you wallet a favor and research this site before you drop a dime on parts.

 

Thank you and yes I have never messed with LS motor before, never had the chance till recently I have ALOT to learn about these motors, currently have the option to purchase a 6.0 vortec motor for $800 obo which sounds like a good deal again thank you for the reply

 

Yes it's aluminum would honestly like an iron block as I heard it can be bored out more and not compromise durability. Yes I planned on forged rotating assembly and also learned that running nos or turbos that o should gap my piston rings further apart, also thinking about forged main bearings not sure if they make any for an LS motor, since this post I have came across a complete 6.0 vortec motor so I might get that instead since its already running, another part I thought about was head arp head bolts and (don't remember off the top of my head) head gaskets that are steel and was thicker was told those upgrades would be good for a turbo or nos motor
