Why does every one want to switch to the 3100 over the 3.1? I talked to the machinest that does all the work for us at the garage and says the 3100 heads dont flow any better then the 3.1 and that the 3100 air plenium is more restrictive then the 3.1. The 3100 has more hp due to having a roller cam, roller rocker arms and a ECM that regulates the fuel/air mixture better. I like both engines but why not use the roller cam and rocker arms and put in a good after market chip in the 3.1 for the same end result HP wise. :D

Actually, 3100 heads DO flow better. The main difference is in the exhaust flow. Intake flow is a just a hair better, but the 3100 exhaust flow is way better. There's a thread at 60* that shows the flow bench #s for 3.1L and 3100 The intakes on 3100 are much better too. Also, 3100 didnt get the "good" roller rockers til 96 or 97

I dunno. Ok the valves are a little bigger so ya could put them in the 3.1 heads if reworked. But you know for the money thats gong to be spent on swapping everything over on to the 3.1 wouldnt it be better to say the hell with the 3100 top end swap all together and go for a 3400 engine swap. :D

The valves werent bigger til the 3400, and the only the intake was .04" bigger. Its the D-shaped exhaust port on the 3100 that makes it flow so much better. The reason to do a 3100 top end swap on a 3.1L is that there are MANY aftermarket cams for 3.1Ls and none (except for regrinds) currently available for the 3100.
