318 Cam Maybe Not
I see someone at least mentioned the Comp 256 in passing.
When I was doing a lot of SBM cam research, I ran a whole bunch of the comp ones on their simulator app with the closest to my stock roller LA spec as I could program.
The XE256 vs the XE262 came out with the 262 only being 10HP prak higher in a MUCH narrower peak. The 256 had a whole lot more torque under the much broader HP curve.
To me that said 256 MUCH better street cam while only giving up 10 HP.
Did the OP say he had a stock LA 318 cam?
IIRC the lift is .399-.400.
The cams I did research on were all in the .450-ish and under range.
That should be a very noticeable improvement.
