whats the differance between 31&3400 motors, i have a dead 31 in 2003 malibu, and a fresh built 3400 longblock can i use 3100 intake ,what problems should i expect?
@TheCharley1957 I believe the intake manifold ports on a 3400 are bigger than the 3100 so it would choke the 3.4 block down that is if the ports even lined up. Gaskets probably wouldn't match up either.
@TheCharley1957 , I THANK YOU, I GOT 2002 3400, AND MY CAR IS 2003 MALIBU WITH 3100 IN IT, I GOT REMAN 3400 LONG BLOCK, THEY GAVE ME ALL ACCS TO THE UPPER AND LOWER INTAKES INJECTERS (EVERYTHING) I JUST DONT KNOW IF ITS GOING TO WORK , I NEED A LITTLE HELP
Wow! This is amazingly sick! Got the same engine on my car and mine eats up oil and coolant... How much does it cost you to rebuild yours? Very good engine rebuild! 5 Stars!
@ebayer25 I believe it cost me around $1800 for the full rebuild. That includes a full rebuild kit: pistons, rings, bearings, oil pump, and gaskets. I also replaced the cam, all the roller lifters, timing chain and gears, and replaced all the valve springs. Machining done was bored 30 over, full valve job and heads decked. Pretty much wanted to keep the original engine and make it new. Also replaced all the sensors in it.
@dallen1993 I will make a video of the engine install and it running as soon as I get the car back from getting a new paint job. Keep checking for a video.
cool! I have a ,04 GT with the 3.4 planning on a 3.5 top swap and solid roller setup with ls1 valve springs and rockers...I like the classic pontiac blue!!! post more vids when complete!!!
@streetvandal Thanks, hopefully I'll get the car back soon. Its in the body shop getting a full paint job. I wanted to cam this motor too but nobody makes a cam for it. I could only find cams for the older 3.1s.
@79TAGio There will definitely be some videos made. I'm still waiting for the car to get back from the body shop so I can do the swap and get her going.

Nice. Looks complicated but a master piece. If possible can make a vid of the car with the new engine?
