383 vs 400

-
5/13/11 is the first post!
We just made 2017!!!

Good topic. Though I think it is settled.
 
If I had each to choose from, the 400 hands down.
 
i thought stock 383's were all low compression but advertised at 10:1 so you could blue print
them to the factory rating and be NHRA legal.I have never heard of stock 383 pistons sitting
above the deck but maybe some were?
..as suggested a 340 has some advantages over a big block in an A body.

Some used closed chamber heads. The 343 HP dual carb 383 was a holy terror in stock eliminator in about 63.

The owners of Spook's Customs in San Antonio had one in a Savoy and I actually was blessed by getting to ride in it twice during the Bun & Barrel cruise in San Antonio. That car is a sucker punch if you're not paying attention.
