I'm looking for a set of 3-bearing S-grind or similar cam (Mod-S, etc) for my 2.7 build ('74 7R case).

I was going to use 3-lobe SC grinds I bought a while back and keep the stock pistons if they looked OK, digging into the motor it needs a full build, so I'm going 9.5:1 pistons, re-coated cyls etc etc.

Need hotter cams to match the new p/c

I wanted to check here before contacting Dougherty/Elgn/WebCam

Thanks,

Talk to the cam guys. There's been developments in the last 40 years since the S cams were made.

Solex cams work well if using carbs.

With the larger 2.7 displacement, std S cams work fine in my experience.
I had a set of Solex cams on my RS spec motor (8.5:1) by mistake.
When I finally got the correct stock S cams installed, it was a totally different animal.
It was fine around town and a beast on the track.
The car had MFI induction in case that matters.

I'm building another one of these 2.7 MFI motors soon.
It will be higher compression (~9.5:1) and I'll look into the S mod cams from Dougherty.
At about $900/pair, they're not inexpensive.
It is still going into a street car.

Nathan, my 2.2 has S cams, but E heads so I need to go to Solex. I could pull them in a month or so. Taking off to Florida next week. I could take a few pictures for you. Best, Mark

I have a set of 3-bearing MOD S cams if you're interested. (I'm in NOVA)
