3.9 engine tuning.
Discussion
Need some advice for tuning a 3.9 to get more power and torque.
Myself and 2 mates have bought a trial car with a 3.9 v8. It's stock and ripe for some mods to get a bit more out of it.
What's the best cam to get good power out of it, want this to sing as i'm going to give this car death..
Plus headwork, what's good and what's not?
( it's not my wallet that is paying for the tuning so i want to go silly with it... )

It's a genuine Tomcat he's got. Built in the 90s, been standing for a while but it's solid and needs freshening up.
The engine wasn't in the car, it had a 4.6 fitted at some point.
The 3.9 is gubbed, won't turn over by hand, plugs aren't in right, his bore cam has been down into the engine and what he can see is a lot of very rusty Pistons.
Typical.
However, I have managed to get a lead to a 3.5 block with heads.
No pumps, carbs etc. Do the pumps etc from the 3.9 fit the 3.5 if they are good?
Used to working on 2/300tdi and tdv6 engines but never done v8 stuff so it's a stab in the dark.
