Speed Density Cams
#2
IMHO and experience ...... a CI custom cam tailored to your combo and expectations will give some speed density "surprises" w/out any driveability problems.
#3
I ran a B, a E, and a wolverine 1087. With SD, no problems. Went 11.60 @ 116 with one set up. It may surge a little from time to time, but why would that be a problem. It my mind it just sounded tougher when it did that.

Quit with "custom grind" answers already. I highly doubt he's done with his combo to necessitate a custom grind cam. When you looking into something for speed density your looking at duration and you don't want it to surpass 224 @ .050.

Cut at a 116, 114, 112 or 110 LSA? ....... my X-303 is a 224 @ .050 cut at 112 LSA and 5 degrees advanced.... does it work OK with a speed density setup?........ .... of course not! ... will it work OK at a 114 LSA instead of its 112?...... NO.... do YOU know why?

What off the shelf cam other than the outdated Motorsport cams have anything other than a 114 lobe center until you start to look at serious n/a cams etc that are built for a specific app?
Why is it the first thing that's said when somebody wants a camshaft for their ride is "get a custom grind man". The camshaft is the LAST thing you pick when building your motor, and THAT's when you get a custom cam, not when your wanting to wake up an otherwise stock or close to stock mill. Why should he waste his cash on a 300+ dollar cam when down the road he may upgrade to MA, or change heads, or intake, or anything and then the coin he saved on the custom cam was wasted as his app changed?
Can you tell me this?
Every 1st Gen Lightning running Ford SD set ups are going with the exact camshafts I'm talking about or are going with stock HO cams if going forced induction. Something at 114 lobe center and NO MORE THAN 224 degrees at .050 with great success. Yes I know it's more cubes, thus the reason you go with NO MORE than 224 degrees.

Oh and to answer your question yes I know why. The MAP sensor in the SD set up is sensitive to vaccum conditions as it's trying to adjust for the car with passed conditions instead of current conditions like MA set ups.

The stock HO was only used in FI for the Lightning set ups, other wise it was 224 degrees or less @ .050 even in N/A set ups....
I agree to disagree in a custom cam set up for him as I highly doubt he is done building his engine and a custom cam set up would be needed again and again as he is changing parts only exponentially increasing his build cost. When he changes head set ups or intake set ups or whatever, his custom cam is no longer custom to optimize for what he has....
