Considering a 355 pump gas build with this clay smith cam HR-8082-8-csr. Would like to hear some feedback from guys who are running it. Thanks.

That would be a great cam for a 350. Even better if you ran the AFR 180s. I’d say shoot for a 10:1 compression.

That’s a Straub cam. I’d give him a call if you want to talk more in depth about your combo.

Those are good numbers. Maybe if you can, run some 1.6 rockers on the intake.and get as much compression as possible. I have run a similar combo. It will be a little sluggish out of the hole for a cruiser, but will run really good up to around 6000 or so. Call Chris Straub, like mentioned to get more.

Would afr 195's be to big for this cam with 10.5 compression ratio? Its going in a 69 camaro with a t350 and a 3000 stall. 3.55 gears and a 27" tall tire.

Like nitro fox said, unless you have the 195s already, 180s would be better. Straub designs those cams for specific displacements with specific head flow numbers. This cam is designed for 350-360 CI with 180cc AFRs.

For compression, I run 11:1 on 91 pump with 36 degrees but my cam is larger than the one you’re looking at. 10.5:1 would probably be ok. However, you don’t want to get it all put together just realize you went too high on the compression for your cam choice to run on your desired fuel.

I also disagree that this will be sluggish out of the hole. Depends on the combo. 3000k stall and 3.55s will be a blast in a street camaro.

I’d just call the guy that designed the cam. He can give you no sh1t answers on the combo.

I ran the version with more exhaust duration. 221/[email protected] and .510lift. 9.7:1 compression. Using a set of Performer RPM heads/ intake. It ran 12.90's in my Chevelle with T350, 3800 stall / 390 gears and 28" tires. Had a bit of lope bt good manners. Easy to drive around and still plenty of power for having fun.

Just for comparison,
I ran a HR with a few more degrees then the one you mentioned in my 355.
227/232 @ .050" and a smidge more lift .528 w/110 ls with AFR 195 comps and a AG and 1" open space and 780 dp. 10.1 compression with steel shim hg to raise the compression.
(pistons were down in the hole.030)
TH 350 TCI street fighter (3k) 3.73's 26x10 slick. It went 11.70's at 113/114 with good air.
You have a lil less cam, same stall, lil less gear. Pretty sure gen Ones weigh the same as my nova. They share the same subframe!
I think you'll be fine...
Don't mind Pops. He was a lil confused when he taped this pass for me.

I think it would be news to the good folks at Clay Smith that Chris Straub is designing their camshafts.

There are a series of cams that Chris designed/spec’d. They work great.

Kind of like when Harold Brookshire was designing cams for Lunati.

No first hand reviews of this exact cam? I've searched on you tube and different forums. Couldn't find anything.

Cam works very well in AFR headed SBC or SBC with heads that have a 75% I/E ratio. For a 3.48 stroke SBC going up to 6500 rpm, I would use a set of 180cc AFR. 195's if your going to turn the engine over 7000 rpm for peak power. That profile will in a 10 to 1 SBC with at 350 to 360CID will make 400+HP with that cam all day.

385 minimum ft.-lbs. torque between 2500 and 5600 rpms, that thing probably pulls pretty good. Nice flat curve.
