416 Longblock built-need help deciding on camshaft-SR or Ft?

I would do a hybrid, hyd roller cam/ solid lifters lashed tight around .004 .That way you can use less spring pressure get more power than a sft and still have reliability/ longevity.Plus the purchaser can say it has a roller cam and makes it more enticing.Second choice would be a solid flat.

This is exactly what I was thinking.

A NICE hydraulic roller cam with solid roller lifters. You can lash it at .002 cold. With 160-180 on the seat the rollers will live for a long time. May even consider bushed roller lifters rather than needle bearing rollers.

Whatever you do, the end user had better understand the number one killer of roller lifters is wide lash. A close second is dirty oil. Gotta keep up on the lash and keep good, clean oil in it.


After all that, I'd slap a HFT in there so fast it would make yer head spin. Most guys don't even know how to lash valves nor do they want to learn. Neither will they be diligent about doing it.

So HFT for this unknown customer.

Did any of this make sense??
