[QUOTE="not2melo, post: 9279, member: 90"] Thanks buddy, I am still doing lots of reading on the pros and the cons. Either way its very interesting and Manny & John are just down the Hwy from me so we can make it happen very fast if I decide to go that way in the fall or over the winter time. I think the 383 would be the cheapest option as you are just adding a forged crank with a 4" travel for added cylinder depth which means more cubes. I dont think you can go deeper then the 4" or the bottom piston seal will pop right out the bottom of the sleeved cylinder. If you want to go 402 or 427 then you need to have the engine re-sleeved for the addition of larger sized pistions. I have been reading about re-sleeving the block, here is some tech info in a artical about re-sleeving a LS1 to a 427, very radical.

But then we are talking some serious money for the work that needs to be done if you go more then 383, even though the LS1 block can hold it, at what point is it just cheaper to drop in a already modified 402 LS2? I was trying to figure out what was the next best bang for the buck to get some more HP out of the car without adding a FI option to the picture as that would put me out around $7-$8k. I am going to keep on reading and see what else I can find out. [/QUOTE]
