420a cam

[brassc2007]

ok i searched and tried to find some info on this but to no prevail so now im going to throw the question out and see if anyone else has done any research on this crazy topic.

Ok my buddy has a nissan 240sx and we were talking the other day bout the normal topic of me trying to get him to do the rb25det swap and him wanting to keep his motor anyways lost cause of discussion there. .
well when we were talking he brought up the topic of being able to change out his stock intake cam for a stock exhaust cam in its place and see some gains. This got me thinking and i have not read anywhere about a potential of this on a 420a at all as a cheaper mod. I was wondering if anyone else has thought of anything like this and if it is even possible, as im not sure of the durations or anything on the stock cams at this point. Please dont bash me im just throwing this out as a topic of discussion and maybe an idea that will lead to more.

Ok so i finally found the stock cam specs for the 420a they are
Advertised duration--219/221
Duration @.50--------166/172
Gross lift w/1.75-----.273/.323



so the question remains will swapping out the intake cam with the duration of 219 and a gross lift of .273 and swapping in a exhaust cam with the duration of 221 and the lift of .323 be beneficial for a small horse power gain or would it be a waste of time and effort

So no-one has a suggestion on the possible power increase or opinion on this mod

Cam position sensor is on the intake cam right? would have to drill and tap the stock exhaust cam to use as intake.

EDIT I WAS INCORRECT IN ASSUMING THE SENSOR WAS ON INTAKE.

Cam sensor is on the exhaust cam.
