View Full Version : Original Coupe Camshaft Sounds Like a “B” or an “E” Camshaft?

I know this is the Roadster forum and I was hoping for more traffic. What camshaft does the engine in this video resemble?

Depends on several things. What's your compression ratio? More duration will make the cam idle rougher and perform better in higher rpms.

E is more streetable, a little more lift but less duration (and a wide lobe separation angle), i.e smoother idle.
Easier for the average person to drive.

B is for higher rpm, more duration (and a tighter LSA) less lift, probably makes more peak power. Rougher idle - better sound. Needs a 5-speed or a mild stall converter for an automatic. With a lower compression ratio, wants to fall on it's face trying to take off.... need to rev it up more to get moving.
Needs more attention to drive.

There's more to it than I mentioned. Cam lobe ramp rate, compression ratio, head flow numbers, etc...
Before you buy, check out aftermarket cams, Crane, Crower, etc... You'll find parts better than Ford.

I think it's impossible to identify a cam by listening to the engine. Way too many variables. Ducky is right, way better bumpsticks out there than the old Ford letter cams. I wouldn't use either one if you gave them to me.

Sounds evil to me. My Mk 3 has a 302 that started life as a 1991 Mustang 5.0. Converted to carb with Edelbrock intake and next big project is aluminum heads. Considering installing a new cam along with the heads. Bonus if engine sounds like an original.

I built the engine in my Daytona with the goal of higher rpm vintage sound and feel. The cam is an Engle with solid, flat-face lifters and the old firing order (15426378). The cam number is EP 22/49 with 113 degrees of lobe separation. I’ve got 44mm Weber IDFs on it and an internally balanced rotating assembly. At idle it sounds rough but that’s mostly the weird, uneven pulsing coming from the pipes on each side. At some point my goal is to get it out on a track and really open it up.

Based on this and your sig line, you have one primo Coupe. I bet it sounds great!
