[CobraV8]

Thanks a bunch to everyone, this answered all my questions. I will do some calulations to find out if the stock dog bone and spider assembly with a reduced circle cam or the link bar lifters and a standard cam are more beneficial for me. The engine will not be spun past 6000-6200RPM anyway because it's got a cast crankshaft, so high revs shouldn't be an issue.

Thanks again!

Simon
