![]() There have been people who did the 3400 top end swap and used the stock PCM, but like any other mods (cam and such) it's best to tune. You can get away with using an adjustable fuel pressure regulator, but tuning will take full advantage, and you will have to use 3400 pistons.

![]() When I FIRST did the "update" to my 3.4L RWD Camaro (mind you I'm the guy that started all this nonsense thinking)...
I used the 1996 3100 heads, 1996 3100 intake (upper/lower) and 3400 throttle body (cause the 3.4 wont bolt up). you HAVE to do the pistons - no matter what. After bolting all this together, i *had* to use headers, normal exhaust manifolds wouldn't fit (2 weeks with a dremel and breaking one told me that) - and I managed to get everything to work FLAWLESSLY without tuning! I also went from 140.2rwhp / 183.5rwtq -> 170.3rwhp / 207.1rwtq. WITHOUT TUNING. now yes, forced firebird is right - you should eventually tune. Upgrading to the 3400 parts did nothing to effect the ecm (stock 3.4L RWD ECM) - but once i put in the custom cam, all hell broke loose and i now have a 10.5:1 AF Ratio So yes - eventually a tune will be needed, but if you dont use a custom cam you can get away with just using the stock ECM. I'm not sure how an auto car will respond to this (I have a T5 manual), but you can try. Peace out. -R

go there and you can see the INITIAL swap i did with the 3100 parts. things are 99% the same with the 3400 - the fuel rail is part of the similarities.
