The block will have to be resleeved (dry or wet) and fitted with a stroker assembly.

My advice is talk to Steve D. at R.E.D >>>>> sponsor.
He is the only one I would 100% trust for this.
Why? because he is the develloper/pioneer of this procedure.

Save up for a sleeved ls2 block and don't bother with the LS1... You'll need a 4.125 bore and a 4.000" stroke!

Better off doing an LS2 402. That is just a stroker crank. I believe 383 is the biggest you can go on just stroke. To get the 427, you need to bore the block, which requires re-sleeving an LS1 block.

You don't have to change your pcm. Just get a 24x reluctor crank and a knock sensor extension and you are good to go. You still have to have it resleeved of course. Oh yeah and lots of money.

Still finishing the boost controller. It's almost done. It looks REALLY nice. I should be doing some tuning tomorrow. I would love to have the car done for Saturday RSD but I don't think thats going to happen. Jim doesn't tune on Saturday , unless I can talk him into it $$$!
