A few 2.7 i questions

[Mr Deagle]

In my build, im going to be using an e crank, with i rods. with custom pistons, and schrick 284 cam, schrick valves, and schrick springs

[SpecM]

-BUT I would suggest useing longer (135mm vs 130) "i" rods. Better revability, better with the cam too.

[MrK]

I used 'e' rods and custom pistons, so from first hand experience, I say yes you can. A 283/283 cam can be used with stock springs, if they're new. I wouldn't try to use them with 15+ year old springs.

Can you use the 'e' rods (with custom pistons, of course), or just the 'i' rods when building this motor? Also, does a 283/283 cam require performance valve springs or would the normal 'i' springs be fine up to 7000rpm?
