I know its a stupid question, but will the 3.1 TGP manifolds bolt right up to the 3400 heads without modifying them?
I remember reading through a couple swap post's but don't remember if it'll work, Thanks!!
yes they will, you have to hollow the exhuast manifolds to match the D port on the 3400 heads, also modify 3.1 gaskets.

fweeewwhhh, good to hear.
has anyone ever experimented with making turbo PLOG's like with the 3800?

x2. Its a VERY close fit, but it will work as long as you modify the gaskets and make sure you mount them up centered.
