List of 3400 Manifolds and heads?

Been searching hours these past few days. Plenty of articles about manifold and head swaps from the 3400 and not the 3.4 but no concrete list of vehicles to source them from nor the parts from either vehicle that need saving. Anyone have a list or mind starting off? Searched and searched but everyone seems to say do this and that but do not specify where and what. Sorry for the question I am sure that has been asked time and time again but searching is getting old. FYI this is for a 92 Beretta with obviously the 3.1. :runsies:

The best option for you would be a full 3400 SFI engine swap. "3.4" was used in rwd camaro applications and isn't really a worthwhile swap option. You can wiki the 3400 SFI engine to see what applications it was used in because it's quite broad.

Thank you for the reply, 3400 swap may come one day, but for now why pull a running engine whilst in a tight budget? Going to use what I have until it pops. Just researching for when the day comes or I come across a 3400 top end for peanuts. Thanks again.

Don't confuse a 3.4 tdc with a 3400 or 3.4rwd

A 3400 top end will physically bolt to the 3.1 but other custom parts, such as push rods, will need to be bought to make it work.

Correct.
Also to look at performance gains and work involved for a hybrid vs complete swap upgrade, not even tossing in cost, for comparison; The 3400 swap is going to be a logical route... aftermarket support is about moot these days.
