2 Barrel Holley Manifold

[kenny66]

Hey guys,

I am kenny's son, I have a 2Barrel holley manifold and i am not sure if it is for a 186 Red, Blue 202, or a Yella terra.... is there any way for me to tell what engine it is for? without having to trial and error with different engines.

Thanks
Adam

P.S With regards to dad's last post... What type/size  
     Jet can i upgrade a single barrel 186 Red motor
     carbie to? It's a stromberg off of an old HG Kingswood.

Once again thanks in advance for any help you can provide.
