Have the gains between these 2 options ever really been discussed.

For example: can you see just as good if not better gains from a cam and springs plus a tune as you might from a P&P and a tune?

Also what other changes might be gained other than peak numbers?

For example my lsj is on a large turbo set up but stock motor otherwise.

More people are camming now and I'm confident in my tuner as long as the cam options available do work when put in right.

 

Doesn't really make sense to do one without the other IMO. If you are going through the work of pulling the head, might as well do it all right. Proper porting and flow work gives gains much the same as cams, shifts powerband and such. Springs in themselves do not gain power unless they are combatting excessive valve float, but they allow you to rev higher and make more power if the rest of the setup can handle it.

 

I know the springs dont add power but you cant really do cams without changing those things.

I have a spare head so I wouldnt be putting myself out. And one with out the other is more of a budget thing.

I really wanted to know if there is more to gain from a cam then a P&P. Basically performance and price comparison.

 

I'd rather be ported before I went with cams. That way I would take my flow bench numbers and give them to my cam designer along with my header and intake manifold info goals and whatnot and get the cam designed for my application that'll blow any off the shelf cam out of the water for slightly more expense.

 

Having my head ported by Euthanasia completely changed my car....in a good way
