Anyone Have an overlay of 112LSA VS 114 LSA? Just wondering about hte difference in Peak HP RPM? I am going to do a 224 camshaft. Dont want to rev it to the moon. I would love to see a dyno overlay of the same camshaft on 112 vs 114.
TIA,

Cool, I knew the 112 would peak sooner, but I did not realize we were talking 2-300 RPM sooner. I dont want to rev my stock short block past 6500.
BTW, here is a graph of Thunders 224 on 112
It peaks around 6100, would probably want to shift around 63,6400. I guess the 112 is right for me, you would probably want to shift the 114LSA 224 around 66,6700. If anyone has a graph of a 224 on 114 in a 346 I would love to see it.

112 should start peak from 5800 >6000 and 114 from 5900>6100
My 224/220 116 peaks at 6100

My TR224 / 114 dyno is attached below on stock heads. Still peaked at 6000-6100. I think the 114 will peak slightly later, but have a more broad HP peak.

Can anyone overlay the two graphs in this thread?
This is interesting, if I can get the 224/224 .580/.580 on 114 to peak at 6100 I will go that route.

The 112/114 peak is affected by other mods related to the flow in/out of your motor and by the advance in the grind. The LSA is not the only thing that determines the peak of a cam, just part of the whole equation.

Sux Marc but I have to agree with you on this post 
The install affects the power band. If you install it dot to dot the 114 will peak later UNLESS the 114 is a 4 degree advance ground in and the 112 was zero. An adjustabe timing set would help you get the band where you want it but it sounds like you want a 112 lsa.
