408 rwhp dyno

That was a brain cramp, hyd. flat. All in all I am very pleased, car has great street manners, with the 4-speed it feels alot quicker than my quarter mile time slip shows.

How much does a 4 speed take compared to about 20% for an auto? My 904 / 416 probably makes 400 RWP based on 20% loss so your stroker sounds like it is making 500 HP like most with that comp do.
