I was thinking about getting a 5.3 block and using Callis 383 rotating assembly and boosting it to 900 to 1000hp. Can the 5.3 iron block handle this?
I have a ls1 block but I dont think it will last very long at this power level. I know the 6.0 block will handle this but 5.3 blocks are cheap and this is a cheap 1000hp budget build...lol

re sleeve your ls1 with some good sleeves and it will hold 900ish hp and still be 95lbs lighter

o yeah when you do make a 1000hp it wont be cheap..... it wont take long **** breaks, its only as strong as the weakest link

I know it's not gonna be cheap cheap but I'm not buyin something I don't need. Basically can the 5.3 block handle that amount of power being a 383?

Are you talking about boring the 5.3 out to 5.7 specs and adding a 4 inch crank?

Yes. I have a 383 built the same way. Im planning on putting boost to it soon. maybe not making 1000hp tho.

yes 5.3 bored to 5.7 specs and throwing in a 4inch crank....it wont see 1000hp all the time just when racing a bike....basically a highway car

How much meat is left after the bore? I know it has been done for na, but not sure if the walls get too thin, specially for 1000 Hp.

why not forged the 5.3? or Build a forged 346/7?

well 346ci would be harder to make the 1k, and spool up will be a bit slower. I had a buddy with a ls1 383 with around 800hp and was fine and is still running good, so maybe just use the ls1 with a 4inch crank and boost it, but I kinda want iron block tho for peace of mind...lol

I think i'd rather build a 390, shorter stroke you end up with a stronger crank

you can build an iron 347 out of the 5.3

so a 5.3 block with 3.89-3.90 bore and 3.75in crank? or are you talking about a 6.0 block?

No, stock crank + bore out the 5.3 block to LS1 specs.

no i was talking about the 390ci, but AES racing what is the shipping on the 390ci turbo motor with callies parts?

Our 390ci engine is 6.0 iron block, 4.030" bore, 3.825" stroke.

Shipping, $150 to a business throughout most of the country for a shortblock, Seattle WA is $200, highest price I've seen.

Is the Ls1 bkock really that weak? I was looking one over the other day, and the cyl's seem to be pretty beefy and are siameesed.

I have seen 800 hp on the flywheel with the ls1 with (darton sleeves) I think that is what they where called

That's a good price for that short block and shipped but I don't wanna built a ls1 block and have a cylinder warp or crack on me and wreck the motor
