i have a edelbrock victor x intake manifold and i compared it to a a JG edelbrock victor x and the runners seem a little longer on the Jg edelbrock. Anyone ever did comparison on measurements? Are there any significant differences? i just eyeballed it and i cant be sure.

 

anyone know the differences? i personally only compared a b16 Jg edelbrock to a victor x edelbrock for gsr. The gsr one seemed to of had a shorter runner length.

 

Arent they both the same thing? You make no sense

 

 

Are they the same? idk the only manifolds that i had for comparison where for different applications. One was for gsr and one was for B16. The one that was for b16 was a JG edelbrock(Jg stamp on plenum) and the gsr one one was the edelbrock victor x(no jg on plenum).............The B16 application(Jg stamp on plenum)has slightly longer runners than the Gsr app(no jg on plenum)

Has anyone checked to see if they made any changes since Jg no longer works with edelbrock?

 

Never seen them both side by side before, but i always assumed they were the same manifold, just the name changed. I have a JG manifold btw...

 

looking for confirmation here.

 

why would a manifold made for a b16 be the same as a manifold made for a gsr the intake sides of the b16 and gsr are diffrent. slightly diffrent flow characteristics. even the b16 and type r manifolds would be slightly diffrent and they both use the pr3 head but flow is diffrent, and cams are diffrent so they make the manifolds to accomindate for all those diffrences

 

Hence the reason i am looking for confirmation. If you do not understand please read again. Anyone with knowledge please post.

 

are they for the same head as most people would say call up edlebrock and ask them

 

k thanks for the help!

 

called edelbrock hotline. Its just a casting change. manifold remained the same.
