What type of exhaust? logs and snails, or headers.

On a bbc, ABOUT 230* for logs and snails, and well into the 250* for wet headers.

Some will be trial and error with an ls.

Compression ratio, intake design, and how the cooling is plumbed can/will effect (affect?) reversion

more info is needed.

9.6:1 compression, marine power center riser manifolds, water ran through thermos tack setup

Id say something around the 230 range, but LSA has a lot to do with it and also the overlap.

In comparison, ill be running headers, dry at idle and manually injecting water and i just ordered a 235/242 .621"/.592" 111+3 cam.

if i was looking for a "wet" exhaust system, id look at somehting around 223/230 maybe this one http://www.briantooleyracing.com/naturally-aspirated-ls1-ls2-stage-i-camshaft.html
