Thanks for the reply, I thought the 675 claim was a bit "Optimistic " but I don't really plan on making that much HP, so I was thinking that that kit should be good for 500 hp at least, which should give me piece of mind for the 400-420 rwhp I'm planning on making from a N/A LT1.
The plan was to get a used lt1 tranny for $500, the kit for $677, take it to a local tranny shop and call it good. I figure it would still be cheaper then buying a "performance" unit that usually starts at $2000+. If you think you can put together a kit of parts for me that would be better than the pro-built kit, OR, a kit that would better meet my performance needs for less, I'd be interested. Right now I'm focusing on the engine, PCMs, shit like that, I'm just getting my ducks in a row for when its time to get to that part of the process. Let me know.
