Need Advice: Building a '99 Block.
Need Advice: Building a '99 Block. I did a lot of searching but it seems like once I think I found an answer the next thread I read brings me back to square one. So I figured I'd just start a thread to try and answer my question.
I was given an LS1 with casting number 12559378, which going by this site- http://www.rapidomarine.com/default....sting_id_.aspx , is a 99-up block. It seems from what I've read they have oiling issues due to the lack of oil passages compared to the later blocks. I'm wondering if it would be worth it to build a stroker out of the block. Hone it .010" over and add a 4" crank along with forged rods and pistons. So I'd have a 383 and also occasionally run a 150 shot. Is this block really that useless that no one builds off of it? If that's the case I'll try to sell it since I wasn't planning on building a motor now anyway, this one just feel into my lap.
Before anyone says it I know that an LS2, LQ9, etc may be a better block to build off of but that's not what I'm asking.
I appreciate any input. Thanks.

I'm trying to find out the same thing,is it worth it,I mean I have tried to find a answer for a few days now and come up with nothing,I'm trying see if pulling it cleaning,rebuilding it up a lil is gonna be a good idea ,
Well lets look at this in worse case senario... How much can you sell the block for vs how much you can buy a better one for VS buying a 6.0 iron black that you dont have to worry as much about... I know you said you didnt want to hear about the 6.0 block, but when it comes to practicality, your pushing your best option away...
I'm not looking to do what you were thinking but my buddy told me stroking a ls1 wasn't the best idea,I just kinda wanna know what can I do to beef it up a lil to handle the abuse for next year

The oil pumps or oiling issues? The pump would be replaced, probably by a Mellings unit. I'm not looking to make crazy numbers just seeing if I should invest my time and money into building a stroker out of the block. If I made 450 to the wheels I'd be happy.

Its not a big deal just use the block and keep a extra quart of oil in her. There are many guys on here running over 500 rwhp on. 97 to 99 blocks including my self that don't ever have oiling issues

Verdad Gallardo Thanks for the input. What size motor are you running? Also, what exactly are the oiling problems? Oil consumption, low oil pressue, etc.
I know 450 is a doable number even with a 346, I'm just stating that I'm not looking to make crazy numbers. My car made 390 to the wheels when I had a 10 bolt. If I can reliably make mid to high 400's NA through a 9" I'd be happy.
Thanks again for all the input guys.
