Taking a 6.0 block to 370ci. Advantages vs costs

I talked to a machine shop and it's around $65 to get the block bored .030 over intead of just honed.

what are all the advantages of taking the block to 370ci? And I assume I will need bigger then stock pistons. So what pistons should I get? Anyone else have a 370?

Can't you run LS7 heads on a 6.0L bored .030 over? Those heads flow more than L92 heads.

l92s flow plenty...no need to waste money on the ls7 heads...after seeing dbrods thread i would almost be tempted to run a set of ''worked'' 243s...

I know, I'm just trying to find some kind of an advantage to running a 370 lol.

Maybe Jon will bring some input to this? He has had nice numbers on what popular belief wouldn't achieve.

If you go with l92's there is an advantage with the 370 over the 364, the bigger bore will produce bigger flow numbers out of the l92's (less shrouding) and maybe, but doubtful the 243's (although numbers would be smaller than the l92's) seeing as they are used on a 3.900 bore and make big number i doubt there's that much difference from 364-370. Remember flow = power
back on topic, if you go 370 i would highly suggest l92's. they are cheap and there is no need to get the ls3 heads, the only diff is the valves which are lighter. Also get them ported mine flowed i want to say 36x on the 4.030 bore and they picked up quite a bit more on a 4.125. then not to mention the extra 5hp u pick up from the cubes thats worth 70$ imo although u might want to make sure thats not per hole. besides that run stock crank with a eagle rod (bought from the right place they dont cost 800$ like they do on texas speed) and a wiesco l92 piston set at 11:1+ and a nice cam, 500hp shouldn't be to hard. make sure u get some one that knows l92's to spec ur cam they like a bit of split on the duration

I'm having a 370ci shortblock built right now. I'm doing everything except the machine work.

03' lq4 bored .030'' oversize, Speedpro Powerforged Flattops with top and skirt coating. GenIV Floating connecting rods, comp XER273hr camshaft, and f-body #241 casting heads for now.
