1991 Olds CC wagon with a 350 TBI, tri Y's dual exhaust, six speed and 4.10's. Homemade cold air. I think I have over rev'd her and am ready for some new valve springs. Have read here about beehives and 1.6 rockers, but most info for LT1 applications. Anyone recommend a good camshaft and spring setup for my app. Looking for Low end torque and more power.
Yes it is a 350 as I had replaced the long block several years ago. Thanks in advance. Steve

I used a stock lt1 cam in my '91 cappy with a 305 and 4:10. i was pretty happy with the results, nothing crazy mind you. its the cheap way to go. but judging by your other mods your probably looking for something more aggressive.

You might want to consider the ZZ3/ZZ4 cam (208/221 duration @ .050", .474/.510 lift, 112 deg lobe sep. -- 1.5:1 rockers) as it's often available as a brand new take-out from crate motors on a popular auction site. I've no experience with it myself but chose it for my street rod '48 Chevy/LT1 project -- yet to be run. The ZZ4 is advertised at 355HP with aluminum heads and 10:1 compression ratio. It sounds like it might fit your needs nicely.

I also chose the Crane 10309 springs after some research. Many will recommend beehive springs and I can't quarrel with that, but, as always, ymmv.

Best -- Gary
