That's a B-I-G cam. How high would idle need to be 1,000-1,100rpm? Would you need to run a vac pump to have the PB work?

These G4/G5 heads flow pretty good even unported. It would be interesting to see if you could make 650rwhp with just headers, exhaust cam and tune. That Cam...is so massive it would easily do it. But could I daily drive it...um....no.

Here is the opposite....Greg Good ported heads and no cam....

I’ve done numerous 25x 26x cams in 427 c6 z06s. So little more duration in a 513 CI v10 may not actually be that bad

Just got my 98 back, has around 250 duration(don’t want to give exact specs) and it drives better than stock. I was expecting a small amount bucking and surging, absolutely none. Dan Cragin and his team are miracle workers.

The cam requires new lifters, springs, and push rods.

Any camshaft would require that, any worth doing

No drama launch and it pulled a 10.29. Nice
