2.8 ***3.4 Compatability

will an intake upper and lower from a 2.8 v6 or 2.8v6 rear wheel drive s-10 bold up to my 3.4 without any problems? also, can i just use my lower intake or my 3.4 upper intake?

all rwd 2.8/3.1 intakes will bolt to the 3.4 block. FOr MPFI applications, if the engine didn't have a CSI (Cold Start Injector), then you can reuse the base manifold for swaps. What engine swap combo are you trying to do?????

i want to run a 3.4 motor with a 2.8 lower intake, and then a 3.4 stock intake that is ported and custom made with a throttle body like tiagos, and vipers. will the 2.8 lower take flow better or have any benefits over a stock 3.4 lower take, b4 boring

except for the ones w/the cold start injector, they're interchangable. Some have even used the earlier ones w/the extra injector for an extra burst of fuel ;)

[whiteThunder]

are they better than porting my stock ones? is it worth picking up?

no


is it worth picking up?

sure, polish them up & gasket match,

The port for the cold start injector on the 2.8 manifolds is also a great place to mount a nitrous solenoid.
