Ok, then let me tell you a bit of my desires. It's an M6. I like a lopey idle, but don't want it to sound like it's going to stall. I'd like to gain 30hp or more. I'd like to keep the revs at 6500 for the end of the powerband.
do a search for 224r or a 228r, they're both very proven cams with excellent driveability.
The LSA you choose effects the idle "chop" and powerband of the cam. Roughly speaking, the lower the LSA, the choppier the idle and earlier the power comes on. The higher the LSA the smoother the idle, and the later the power comes on.
Very roughly you'll gain 40hp or so with the 224R, and closer to 50hp with the 228R with a good dyno tune. Contact Texas Speed if you want more expertise here, or Ed the cam guy.
Gotcha. I figure the 114 or a 113 might be my LSA, but I should talk to an expert. I keep hearing good things about texas speed, so maybe a custom grind....who knows? I'll be doing the work also. I've been wrenching for almost 20 years on various things, so i'd feel silly having a shop do it.
Good, glad to hear you're doing it. It was a learning experience for me, but the feeling of doing it in your garage is awesome.
Texas speed offers some nice cam packages, call or email them they're great people.
Also unless you're tuning yourself, contact a local reputable LSx knowledgeable tuner and tell them your plans.
Just to mention, you should maybe think of doing a new oil pump, timing chain, and have a new timing cover gasket, coolant, and water pump gaskets ready to go.
You'll also need a 3 jaw puller for the crank pulley, and something other than the stock bolt to get it back on unless you're doing an underdrive pulley as well. And a spring compressor, and a spark plug threaded air fitting to hold the valves up when you change them, or do the TDC method.
