Cam swap differences
Ok so I am swapping my cam out for a custom grind from TPIS. I am not very knowledgable when it comes to all the things like ramp differences and all that. What i would like to know is how my new cam will perform compared to the old cam. Should I see alot of difference in power? The engine is a supercharged 383 and that is why I went with more LSA and a bigger split in duration. the specs are below. Thanks
Comp 280 XFI (old cam)
.576 .571
230 236
113 lsa
Custom grind
.530 .545
233/241
115 lsa

Pretty minor differences. May lose a little in the mid due to the longer LSA...
I don't get why your lift is going down, while your duration went up (on the intake side)? Doesn't seem like a move in the right direction to me.
