I'll be getting to my engine build some time next year. My machine shop guy tells me that I should not reuse my cam because the lifters have rust on them. He claims that most of the cams he's seen reused with new lifters fail due to the changes in engineering and metallurgy over the years (this cam was made in the late '70's) OK; this much makes sense, a new cam and lifters can be had for around 2 bills.
I loved the way that cam ran and sounded. It was a split-lift, which apparently they don't make any more. I would like to duplicate as closely as possible without breaking the bank.
Here are the numbers off the box:
Lift (net) .450(I) .475(E)
Duration 298 308
Opens 37 86
Closes 81 42
Overlap ------79 degrees-------
@.050 lift
Intake Exh.
Lift -------- ---------
Duration 232 242
Engine/chassis specs (proposed):
340, 11.5:1 TRW pistons (originally 13:1 but heads cc'd to lower compression)
Forged crank
J-heads w/1.88s and mild porting
Holley 650 DP w/Eddy Torker or TQ and dual plane (probably Weiand or Eddy)
Headers
Chrysler electronic dizzy
A-833 four speed
3.55 or 3.91 Sure Grip
This engine guy says this cam profile is obsolete as was the engine build, however the car ran 12's and wound like a raped ape. (What's not to like about that?):burnout:
Anyway, looking for a build with similar specs and a cam to match...unless you guys think my engine guy is right and I should be starting from scratch? I loved the sound of that cam and the way the little 340 ran in the old configuration. What do you experienced engine guys think? Me, I think I'd like to duplicate the old motor as close as possible, but I'm open to suggestions.
