I have a question first I have a 355 with 9 to 1 compression LT4 heads and LT4 hot cam. Now the question is if I changed the exhaust rocker arms to 1.5 and leave the intake arms at 1.6 will the car make more power? I know that the hot cam isn't the best for FI but I don't want to tear the engine apart till it is time for a rebuild.

If you were going split, wouldn't you want the 1.6's on the exhaust? The intake side isn't going to have any problems huffing air into the cylinder with the blower forcing it in, but the exhaust still needs the help.

Thanks that is what i was looking for, i was just thinking it would cut down on the overlap of the cam.
