Question Roller cam Vs Solid Cam

I have to pull my motor out to fix a rear main oil leak. While the motor is out I am looking at a bigger cam. I have a Comp Cam 282S now, .495 lift with 232 duration. I am looking at the Comp Cam roller 294. The cam program says I would pick up 60 horsepower with this cam switch. That seems like a whole lot more that I though possible. Is the cam program off. It says with the solid cam I'm at 441 horsepower. The roller cam was right at 500 horsepower. What do you think?

The engine is a 388, flat top pistons, Edelbork RPM heads, Air Gap, 700 double pumper. I'm running a 5 speed so no worries about the converter issue.

Imho, a 294 cam will run best around 11.5 to 1 CR. so check your CR. here.

Re: Roller cam Vs Solid Cam

The 282 or 288 might be a better choice,better mach for the heads.
Both want 10-1
Tha 294 will want 11-1 for a start and larger heads to do its thing.
I run a xr282hr in my 383works great with manual tranmissions.

Go roller! I picked up 70 hp with roller lifters, rockers and timing.

Revs quicker, higher and seems smoother delivery.

Thanks guys, I had no idea you could pick up that kind of power switching to a roller cam.

Re: Roller cam Vs Solid Cam

Please call UDHarold here, (662) 562-4933 and ask him to make you a SB copy of the BB solid lifter cam he created for me.

It's BB spec's are;

278/149/161, 110/106, .618" gross lift and need's .018" lash on both sides!

I figure that a SB cam's spec's should be the same except for lift, imho...

And if you do call him, please say hello from ol' pdq67 for me.

PS., and this cam is spec'd by Harold to be a solid lifter copy of CC's great old 288AR solid street roller b/c I won't run a solid roller cam.
