More on the Weiand inlet manifold on my 410-
For those who are interested or just need help to go to sleep there is plenty of reading on offer regarding inlet manifold arrangements, specifically square bore and spread bore. I believe 410 and 411 original manifolds were spread bore. The Weiand 7403 manifold is divided square bore. This means the Sniper should bolt straight up.
The question is whether I will get much benefit as square bore is better at higher revs but may lose torque at lower. The 42RH gearbox has a lower first gear which may offset this. I'm hoping that combined with decent tubular manifolds the improved breathing will give further improvement to fuel economy.
If it doesn't work out, Andrew is at the front of the queue for parts to make a fire breathing monster.
