Web 121/125?

Post by prerunner1499 » Thu Feb 03, 2005 2:23 pm

What if any info does ayone have on this cam?
Im trying to decide on a cam to go into a 2187. I want a motor with good torque curve, and will make power in all rpm ranges. Will be run in a light baja bug. It will see 5500rpm+ from time to time :-)
I DONT want a motor that only makes power from 3k and up. Heads will be CNC 044 mag plus with a little more messaging by me.
Carbs, either duals, single 44-48 weber MX if they fit under my cage, or CB efi.

Torque monster with a nasty powerband ...

The 122/125 is better for offroad though, depending on headwork

I have a Web Cam 122/125 for my 2275 type 1. It has a very nice low end grunt and my engine has a very flat torque curve from 2500 to 5000. I don't think you will get close to it with a 120 or 130 brand X cam.

Yes, No H20 built his engine here at my shop.
Due to ramp rate this cam is ONLY compatible with a stock rocker

I have it in my 2276 and really like it. It reguarly sees 6500+ RPM. It's a crazy fast car with the close ratio box I have in it now.

Thinking of running the 121/125 in my 1915...
Weber 44s
1 & 5/8" exhaust.

I have professional (oval) ported and polished 40 x 35.5 heads.

Would this be too much cam for a smaller setup like this?

Don't really mind the motor being a tempramental, but it would be driven on the street...

Don't know too many people running this cam, so Jake will probably chime in. But for reference, my car idles like a stocker and is totally streetable and nasty all at the same time.

I personally think you couldn't go wrong with this cam in almost an displacement motor. It's a very forgiving cam.

I used the SLR surfaced Scat lifters from www.aircooled.net.

If all other factors constant, what is the difference between the output curve characteristic of 121/125 and that of 121. Would it be both have the same maximun HP but at different rpm? Would the 121/125 have higher torque at low rpm range and flatter torque curve than the 121? Which one is better for road racing or track day events?

The split one will produce more torque at a slightly lower rpm.

Would CB's 044 cnc round port be too small for 121/125? The engine will be 1914 with dual weber 44.
