Re: '66 Chevy BBC 396 ?'s......
There are 325hp, 360hp and 375hp versions in 1966. The 325hp version was available in the Chevelle and the full-size Chevrolet. The 360hp and 375hp versions were available in the Chevelle only. The 375hp version was not available with an automatic trans. The 360hp version used a 600 cfm Holley and is the same engine as the 325hp version except for camshaft specs. The 325hp version uses a 750 cfm Quadrajet. The transmission of choice would be a three-speed. When the cars were produced in 1966, the Chevelle used a Powerglide and the full-size cars used a TH400, but I'm sure the truth of that has been rewritten in history along with everything else. If you look at the Classification Guide, it has different weight breaks for the "TH" transmission in the full-size car. The Technical Specs lists carburetors for the "PG", so maybe when that stuff was originally written they knew what was going on.
To answer your questions, the best combination would be a 325hp engine with a three-speed transmission. |

Dwight and others, do you have an opinion on which casting head would be best?
7 options looks overwhelming to figure out...... Thanks again.. Wade O |
