HI,
Is this cam going to be talkative ... have some kind of lope. Sound bite if you have one. OH its in my 1975 318..
OH I had to change to different springs . What came with it were almost an inch taller and wouldn't work , My machinist Didn't want to install them as he said he would have to machine the spring pockets like 60 thousands and was afraid he'd brake thru to the water jackets.. and that pressure might wipe out the cam..

Thats not a big cam that requires taller springs. You should be able to run aprox stock installed height springs which have damper coils and are a little stiffer than the factory 340 springs. No machining of the spring seats required.

I would expect that to have a slight lope in a 318. Certainly wouldn't want any larger cam without a bunch of supporting mods.
