Putting a new cam in my 360
Hello all!
The adventure with the 360 continues. I think it's time for a new cam.
Motor:
360 block.
J heads
Flat top pistons
Zero decked
Bored .30
Performer RPM intake
Eddy 600 (was running Holley 650 double pumper, but it was too much)
Shitty headers
3:55's out back
Approx 9.5:1 compression
Intended use: Street, non-daily. Lumpy is good and low-end torque would be great.
Recently pulled the stock cam out and dropped in an Enginetech ES665. Not much more aggressive than stock. .409 lift, LSA is 109.5, low duration numbers.
It was great and all, until I blew up 4 lifters after putting less than 100 miles on it. Proper break-in procedure (zinc, 2000rpm for 20 minutes, cooled it off). Lifters were 'new' but had been sitting for a while. Oil pressure was good.
Take a look at the pic of the cam now. Looks like all the hardening is cooked off. Seems really quick to do that, but c'est la vie.
So now I'm looking into other cams. The comp 262XE sounds good. The 268XE sounds better. I'm a little worried about the extra lift (477 vs 462 valve and lobe lift of 318 vs 308) with the zero-deck and flat tops. Am I correct in worrying about that?
