BTR Stage 1 Cam This is for my own curiosity. I've noticed that all of a sudden quite a few 5.7 LS1 owners here in Australia are running the below BTR cam with 241 ported heads and LS6 manifolds.
217/23x .615/.636 113
Why I find that interesting is that years ago I was interested in running a sort of similar spec (more mild with much less -overlap) cam from EPS as shown below.
214/232 .605/.598 117
In the end availability to Australia stopped me considering it, but also many on USA 5.7 owners warned off running a cam like this. Reason was because it had a big split with so much exhaust duration. Not suitable for a street 5.7 with CNC 241 heads, LS6 manifold and short headers. It was a bad combination and would hurt low to mid range I was told. Stick to a small split or single pattern cams unless running Nitrous.
However, it had seemed that in the old days using something like the LPE cam below was a good thing. Very popular back then.

What's the current consensus towards cams like these for a basic 5.7 nowadays? Is a big split/ lots of exhaust duration a big no no? How about more lift on the exhaust like the BTR?
