Best cam for NA AND N20? I'm thinking about doing the heads and cam thing again. My heads are fairly old ARE stage II heads (well, they were stage II heads back then... they're more like their stage III heads now) and are really meant for bigger bore applications. My cam is a 224/230 .538/.538 114 cam. I think I could handle something with a little more lift.
If I didn't spray, I'd be going with the 227/224 .569/.563 114 LSA cam, but as I understand it, spraying on top of that cam will give dismal results. Is this correct?
They have a 224/227 .563/.569 114 LSA cam that would be great to spray on, but will give me about 30 less HP than the previous cam. I hate to sacrifice that much NA power.
There's a 224/224 .563/.563 112 LSA cam that might be the best choice for me. It'll give about 20 less HP than the 227/224, but should give me the full 150 HP when I spray.
Anyone have the "perfect cam" recommendation for me? I want the most NA power I can get while still getting 150 HP out of my 150 shot. I want a cam that retains my car's current streetability. This car is my daily driver, and I don't think I'd enjoy driving a 111 LSA cam around every day.
By the way, the numbers I'm using for guestimated HP gains came from Thunder Racing. I realize they're only guesses.
TIA,
Jonny

Re: Best cam for NA AND N20? Well, not sure if this is perfect for you, but here is what I am getting.
224/228 .568/.571 113LSA Should be good all around. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Best cam for NA AND N20? I plan on going with a C2 on a 114. While a reverse split may give great NA numbers, I'm not sure I'd put one on my N2O motor... as well, I think the dual pattern cams are better suited for SBC (exhaust) applications moreso then for the LS1 engine. Just my $0.02...

Anyone else spraying on a reverse split cam that can refute this theory that n20 + reverse split = bad?

Re: Best cam for NA AND N20? I am stuck between the Futral FM7 cam.
224"/230" .587"/.593" 114LSA
And the MMS 229 cam right now.
I know the MMS 229 will fit with my Stage 2 TEA heads milled .015. But I don't know if the FM7 is going to do well with P/V clearance.
