Building a 273

I did a 273 for my 65 barracuda in 2009. It had new pistons in it already when I got it. They came out to 7.8 to 1 with a fel pro gasket. I worked at a shop so I cut 40 off the heads and 45 off the block to get 8.9. I didn't have much money, but I shouldve just bought egge pistons. Better yet, I should've just put a 360 in it. It still runs great with a small solid cam and a stock 65 4 barrel intake. But it's definitely not fast. With 3.55 gears in it, it was better, but still wouldn't burn both tires. It's a nice little cruiser though, needs to be above 3k rpm for any torque.
If I was to build a 273 would use 4.10 as a minimum, smaller engine need more gear,
running 3.55 behind a 273 is like running 2.76 behind a 360, 3.55 is a compromised gearing for a 360 a 273 would need 4.56 to have similar torque to the ground as a similar powered 360.

Why one of my signature tagline is "If your willing to gear it build it if not build a larger displacement, Or take solace in your compromises."
