i have a 109k mile ls1 block in my 1998 z28 and i was wondering if replacing the whole bottom end with a 6.0 iron block would be possible?

using my 5.3 teas intake and fuel stuff would this even be a good idea?

(i figure it be easy to get some forged pistons while the 6.0 is out to bc i'm a bottle baby)

yeah im pretty sure thats possible but me personally i wouldnt do it i wouldnt want the extra weight up front and im pretty sure if u forged the ls1 bottom end it will hold alot more power then ur going to throw at it, just my 2cents

I agree, why not just forge the aluminum block?

Anyways, the 6l iorn short block will be a direct swap.

how much does something liek that roughly cost to forge it?

just rods and pistons, 1000-1500... that is if you stay with the stock crank. also have to add the cost of the shop to bore.(300-600 depending where you go) maybe a new oil pump while your in there 130

just depends how much upgrade you want to do and what power goals you have

You can get a forged 383 rotating assembly for your block for just over 2K. I will probably try to go that route, myself, next summer.

and thats all i would need is the rotating assembly for a 383?

but considering the possibility of selling my ls1 block then forging my 6.0 then spraying the **** out of it, wouldn't it be reasonable at taht point?

I was also throwin around the idea of forging a extra stock LS1 short block. I figure I can find a high mileage short block for about $500. Then get the following:

Callies 6.125" LS1 Comp star rods w/ARP hardware $599
Mahle Fordge 346 LS1 pistons $509
Clevite bearing for complete motor $300 (kinda just guessed on this could be less)
ARP head bolts $140
GM heads/cam gasket kit $150

All parts from Texas Speed comes out to $1698 + shipping for parts w/o the extra short block. Thats using everything else that could transfer from my current motor. Plus the more work you can do yourself the more you'll save.

what would all be needed to do a 383 stroker motor and around how much would that cost????
