CAMSHAFT LSA ???'S

[dickeymoore]

Is there a difference in a 110 degree and a 112 degree LSA in camshafts,will one make more power than the other in the same engine?THANKS

loaded question but i'll give a few basic answers. Wider lsa is better for blowers or nitrous or really big cube motors. Gives a broader powerband. Tighter lsa is better for smaller peaky naturally aspirated motors. Gives a narrower powerband. From my experience a tighter lsa will sound raunchier and may help to run pump gas on a too high CR engine. 110 LSA is generally considered middle of the road and will work good on just about anything.

So do you think there will be a big difference in a 110 and a 112 LSA?THANKS

 

[prairiehotrodder]

whats the motor and is it naturally aspirated? Street or race? Not a huge difference.

The engine is a SBC 400 with a hyd 110 degree cam in it now,will switch cam for a 112 degree Hyd ROLLER cam for street use.

112 will be fine. being a roller will help alot.

David Vizard has some interesting things to say on the subject. I don't have my book handy but if memory serves, 350s like a 108* and 400s like a 106* . I really don't remember why but it stuck in my head.

I think what I read is tighter lsa revs quicker too. My 496 is 108lsa but its a custom grind for my entire combo.
