intake manifold Q?

[nicotine]

i am getting ready to put a 350 in my truck and i need to know if all SB chevy maifolds will work on a 350 because i have a 400 sb manifold will it work? or should i buy a new one?

 

[mrk5]

It should work. I know all the aftermarket manifolds are listed for engine sizes 265-400sbc.

the only thing that will be diffrent would be the plug numbers on the manifold correct?

all small blocks were the same plug # is the same

ex manifold most likly a smog one, and heads on motor are most likly pre smog . the imfumus 7th exaust hole scenereo.

it depends on what heads, TBI, Vortec, or just plain carb heads. the bolt pattern is different on all 3.

 

[nicotine]

they are plain carb heads it is a sb 400 manifold going to a 350. i though 400 plug #'s were in diffrent spots?

 

[big83chevy4x4]

it will bolt up just fine. may be the same intake found on some 350s

400 plug numbers are not different lol

same deal 55-90's cept that in 87-90 some are TBI others are still carb(changeover years) and the center four intake bolts changed the angle they are drilled and tapped
but there is an easy work around for this

put the intake on, you have nothing to worry about

good luck
