306 cam and VS2700 springs?
Yo yo!
I know in the sticky guide it says that the 306 can use the Bullet VS2700 springs and be fine.
The Bullet VS 2700 is a NICE single spring that works with stock retainers, locks and locators. It has 145 lbs of seat pressure and 360 lbs open pressure while handling cams with moderate ramp speeds up to .575 lift safely (GM 846, CC 503, CC 306, my 226/230 .565/.565 111 LSA cam, etc). These are made of a nice quality wire and will live a long time. probably one of the nicest single 'drop in" springs for the LT1. These are $130 shipped thru Bullet Racing cams.
But will it? I'm getting paranoid because I do plan to shift at about 6200 intitally and eventually to about 6600.
My paranoia had led me to using 987 Springs and using the associated hardware:
4771-16 locators
740-16 retainers
611-16 locks
And I hear I need a set of new seals too (are these hard to do?). Also! Are all these "drop" in?
Either way is it needed or is there a better combination to make happen? What would you all use in my scenario? Budget is in mind, but not everything.
Thanks,
Christopher

No personal experience with the VS2700's but I used the Crane 10308 dual spring kit with a similar but slightly larger cam then you and had no valve float issues. Peaked right around 6K and the tune was set to shift at 6200.
Cheap drop in kit good to .6 lift and retains stock hardware .

If you have time to wait I would suggest going with our new pac-1519. Yes its a 1519. 150lbs of seat pressure with a slightly higher rate than the 1518. Also it has a higher frequecy rate to handle more RPM's.

Big peak dyno numbers are great for bragging rights and highway roll races.
Unless you're gonna back up a big peaky cam with very aggressive gears and a huge stall don't be surprised if you get beat by a much "weaker" car at the track.
BTW: OP never said he has the cc306. He mentions it in the first sentence, then actually says he has what looks like an LE1 cam that should run great in a stock shortblock.

OP put 306 in his title.
The dyno chart shows 5200-6500 all above 350whp. Dyno numbers don't mean anything so I won't show you.
Runs same as any other cam only 6 speed does. But it's slower cause you said it is.
I'll leave you alone cause you're the expert on every LT1 ever apparently.
