Alright, school me on stock roller cams....

-
A 360 in an Early-A is a tire-burner no matter what it's state of tune; principally because of the small tire size that the rear will accommodate.

Eventually it will get mini tubs as well. For now, it's just fun.
 
Next hydraulic roller LA 318 we get into, I’m going to measure the lift at the cam. The 1989 5.9 LA roller we installed actually did measure out at .273/.278 lobe lift for an “hypothetical” .437/.445 lift at the valve with a 1.6 ratio in the magnum engine we installed it into.
 
Send it to Ken Heard. Let him grind to a .750 roller if you want for 125 bucks.
 
Not sure the 5.9 had 9.4:1 compression.

Thought it was closer to 8.8.

Advertised to run on 87 octane.
 
Here's the numbers off a 2002 5.9 cam.

Duration @ 0.050: I/E 189*/194*
Lobe separation angle: 111*
Lift @ cam: I/E 0.273"/0.278"
Valve lift w/ 1.6 rockers: I/E 0.437”/0.445”

I sent it to Bullet to get reground and asked if they would give me the stock specs (or close since it had some wear) first.

I think some of the published specs for the 5.9 got messed up and the 5.2 cam is not bigger than the 5.9 cam. But it has been discussed many times and all I have is the numbers above so I can't prove anything.
 
OK here are your Roller Cam comparison Numbers:

First is a 1991 318 Roller Cam that stock grind numbers fit the W-150 Dodge 4x4 Pickup

Huh, well there ya go then. Thanks for looking this stuff up. I'll stop chasing unicorns now.

Yes we all want to know this stuff. That '91 factory grind 318 roller cam is like $100 bucks.

They may have dropped the price on that 2003 360 roller cam. But most of the roller cams start at around $250 on up.

Price plays a factor in cam selection too.

So yeah I want to keep a close to factory grind roller cam in mind should I come across another roller block to build. Want to have the cam figured out ahead of time.
 
Here's what I have for 5.2 and 5.9-

5.2 Magnum Hydraulic Roller 432/432 251/264 113CL
5.9 Magnum Hydraulic Roller 410/417 249/269 109CL

Here is what I have for the 318 LA roller-

391/391 240/240

vs the non-roller-

318 2 barrel 67 Hydraulic 390/390 244/244
318 2 barrel through 88 Hydraulic 373/400 240/248
