Problems with cam
Ok, now I have the Comp cams XS274S with solid lifters in my vette, but with 9.5:1 compression it it's turning out not to be the best cam since I don't have higher compression. Well anyways I used to have the Comp XE268 Cam with Comp hydralic lifters. Around 5,000 RPM I began to have problems where the engine broke up, I believe the hydralics got "pumped up"; this occured even after putting in bigger springs. Anyone running different brand hydralic lifters that work good with this cam? I liked the other cam because it gives you that seat of the pants torque. Can someone give me some advice?

If it's points he can just change to a stiffer spring version like Accel or NAPA makes. Presto...no more bounce.
I agree....you SHOULDN'T be using hydraulic lifters with a solid lifter cam.

but don't complain MY POWER IS LOW
.
in 1972 i learned how to make points work well. i doubled up on the spring and used CD ignition.
shifted at 7000 no problem. switch off the CD and it ran 1 sec. slower in the 1/4
KISS isn't always fastest, just simple
