what engine modifications perform well with l76

[Vz 06 ss]

Hello my names jacob
I own a vz ss 2006
Has 115000km on the clock
Currently has Otr with mafless tune,
Cam with ruffly 113 lobe separation to fit a supercharger down the line,
And all the bits and pieces that are required when changing a cam
3.9/1 diff ratio
1" 3/4 pacemaker header 4 to 1 but changing to 1" 7/8 pacemakers
With a 3" manta exhaust.

So my question is what else is there to help reach the maximum of what my l76 can put out?

Thank you in advance.

What lift at valves?

duration bro... the most important thing about a roller is duration.

What lift at valves?

I'm not to sure what the lift is due to the previous owner put the cam in sadly.
But the springs are rated up to .650

Short answer is forget changing headers, get a better intake manifold instead as that's the main restrictor at this stage. You can always sell for good price if and when your supercharger doesn't fit.
PM me for more details.

We would need all the cam specs, however if the cam is designed to suit a supercharger then it won't be ideal for you engine as is.

mod number 1: fit a cam you know the specs of

springs lift is another useless number without cam specs

So the previous owner installed a cam to suit the new owners future plans?

Nope she fitted one cause she wanted to fit a super charger to it in the future,
When I was looking for a new car I cam across it.
I have all the receipts but it was done by some who is well known at ####ing up jobs,
And it doesn't explain much of the invoice just that it is custom grind roller cam.

must have a part number on it...
