2.8 to 3.4 conversion
Engine Vibraton
I recently swapped in a 3.4 to replace the 2.8 MPFI engine which was about to grenade on a '85 Camaro. It was on it's last leg.
It's a 5 speed and I installed all the tin, timing cover, WaterP, and the distributer from the 2.8 onto the 3.4 according to recommendations in several recipes.
Used the 3.4 neutral flywheel for the clutch plate and resurfaced the clutch flywheel.
The only problem is I have a MAF code now, happened once on the 2.8 BTW when I replaced it last, and a hard virbration at about 3100 when shifting the lower gears. Cruise is fine. I am using the 3.4's injectors. Other things occuring: 115 blv's and a rich signal on the scanner at idle, but it does go back and forth sometimes. I assume this is a lean condition.
Was wondering if I used the wrong damper. I used the 2.8 since it looked like the 3.4's without the additional sensor crap and was newer. I am also thinking about balancing out the whole flywheel with the clutch flywheel as one unit.
Anybody else do this swap?

People on this site generally post a question in one section not three different ones.

Sorry, I just thought the more answers I have the better. I also wasn't getting any more replies on another site. Thanks for all the help.
