Lunati 447

[zrauch]

I am looking into building a GenIII engine for my Monte Carlo. While looking for a stroker kit i came across the Lunati 447. It is in the same price range (roughly) as the other kits. Has anyone used this or would they advise it? I am about to pick up a 6.0 block from a friend later this week and if the 447 wouldn't fit, what would be the next biggest size? Thanks for the help!

you cant use that kit because the 6.0 iron block wont go to the required 4.155 bore. .080 is max and thats a rare block thats been sonic tested. .030-.040 is what your safe at. you'll needa resleeved block, whether ls2 dry or MID wet to get the 4.155+ bore. the darton ls2 dry sleeves will go 4.160 now and about 4.190 with the new design commind down the pipe line. the new MID wet sleeves will go 4.200, the older ones 4.160. are resleeved ls2 will run you around 4k fully machined with billet main caps. the MID 4.200 3500 w/o line bore and final hone.

if you want to keep your 6.0 the simplest option is the 408 kit; bore the block .030 and run the 4" stroke.
