2V vs. 4v

NO SLO PK · 09-25-2000, 03:16 PM

Generally, differences were 200hp for the 2bbl and 225hp for the 4bbl. The K-code 4 bbl was rated at 271.

I'm going from memory, but the 4 barrel versions had higher compression (10 vs. 9.3) and a slightly more aggressive cam. K code motors had solid cams and free flowing exhaust manifolds. I know there are other differences - maybe some one else can chime in?

Nowadays, most 4bbl conversions are done with an aftermarket carb and aluminum intake. For example, I'm using a holley 650 and vintage edelbrock f4b intake on my '65.

Not certain this answered your questions. Maybe someone else can help?
