Toss up between these two cams.
Stock TPI heads, ported, lightweight LT4 valvetrain. 1.5 Rockers.
Holley Stealth Ram intake
9.5:1 compression.
350 .040 over.

Leaning towards the Marine cam because of the LSA of 112 vs the LSA 114 of the XE cam.

XM262H
262/268 duration
.462 intake .477 exhaust
112 LSA
I thought this might be beter because it has more lift on the exhaust side.. beter for stock heads?

XE262H
262/270 duration
.464intake/ .470exhaust
LSA 114

Opinions?
Should both of these run on a stock tune? (I will tune it after)

Is there going to be any noticable difference between the 114 and 112 lsa camshaft?

 

Doesn't the xe262h have a LSA of 110*... Nevermind your tallking about the XE CC cams and the XM grind.

I would go with the XM grind because it has a smaller LSA which will increase low-end a tad.

How about XE 4X4 cam X4262H

X4262H
262/270 duration
.462intake/ .480exhaust
LSA 111

It would probably be the best for the stock heads, which have weak exhaust ports.

 

I was looking at the 4x4 Cam but I thought it may have issues with the computer. My tuning ability is currently limited, as I am just learning.

 

I doubt you will have any problems those cams are so small that they don''t have much overlap or duration anyway.
