It seemed like everyone was piling on you for a few posts there. I don't blame you for feeling a bit defensive.

However I can assure you that if Brent is saying he does not believe the spring/lifter combo was the root cause to the failure, he is not doing so just to annoy you. He genuinely suspects there were other factors that lead to this failure. You should consider digging deeper.

No doubt there are better lifters available, and they may solve the real root cause to this failure. Be warned though that sometimes the real root cause, when left unknown and unfixed, will break the new better parts, too.

I have a 347 with Edel Performer RPM heads, with OEM style lifters. I didn't build the engine and do not know the springs ratings, but it will rev to a 7000 rpm limiter with no hint of float, so I expect they are heavy. No problems yet and over 5K miles.
