Re: 327/275/250hp Super Stock Engine
I run a 66 Chevy II with this engine I can run SS/G,H,I with the 275hp combo or I can run in GT by putting a 4GC carb on it. At my weight I can run GT/G or add weight to run GT/H. I have run both combos. There is no changing heads just the carb. I claim the 65 Nova 327/250 for GT. Ed

Re: 327/275/250hp Super Stock Engine
So I don't get asked this question anymore the engine made 556hp on the dyno with the 4GC carb. The motor was not dynoed with the Q-Jet on it. Obviously it makes more power with the Q-Jet. Thanks. Ed
