[FOR SALE] SBM Cam 280 duration, 525 lift, Lifters, Valve Springs & Keepers, updated with more pictures.

[Cliff Ramsdell]

Hi all,
I have a hydraulic flat tappet cam package that I removed from my 340 Dart. Cam was installed by a previous owner and has about 1500 miles on it.

All lifters are in order and it’s stored in a nice shipping container. Springs are a single with a damper, stock retainers and keepers best I can tell.

Don’t know the brand but we did degree the cam when we rebuilt the engine, it's about 280/290 duration and 525/535 lift, i forgot to add this before, sorry. I also included a copy of a cam card we filled out with the specs. The back of the cam is marked 270/526 so that's about right but can't say who it came from. It also has oil through lifters.

$125.00 plus shipping.

Thanks,
Cliff Ramsdell

I had questions about the cam specs and I updated the post to include a cam card we did while degreeing the cam.

I have questions about the cam specs too, as in
the numbers do not seem to add up;

on the left, the math shows
180+36+64=280 intake, and
180+32+81=293 exhaust, and
Card says 279/287
overlap of 68* points to an LSA of 109.25

on the right;
180+14+41=235 intake, and
180+5+57= 242 exhaust
Card says 235/237
overlap of 19* points to an LSA of 109.75

Cam appears to be installed 4.5* advanced, on the 050 numbers;
but only 2* on the advertised.

otherwise,
nice cam, fast enough ramps, good lift with 1.5s, better with 1.6s.
Seems like it could use more spring, so I could rev it to 7200, lol.
But, as it seems to be a tiny bit bigger than mine; that's going the wrong way for me..

Could have been operator error doing the cam, hard to say. Once I found out it was a 525 lift with stock everything I swapped the cam out for something a bit smaller.

Hi Cliff, do the valve guides have to be shortened? Thanks. Kim

Hi Cliff, do the valve guides have to be shortened? Thanks. Kim

I don’t believe they were shortened, I had them machined down for seals as opposed to the original umbrella seals.

Before machining, stock guides

After.
