bad boy 273 cid why not

It's too much money and probably the biggest draw back is TQ... or it's lack of...
A 289 ford makes 300 ft lbs and a 10 to 1 273 makes...what maybe 275 ft lbs..
Unless you have all the right parts and the knowledge to be able to throw a Razor sharp tune in it...your going to be disappointed..
Anyone ever driven a GT 350 mustang? I have...and you step on the throttle at 20 mph in second gear it's like stepping on a tamato...nothing happens...
Now that same car from a dead stop is a whole other thing...it Really takes off and motors...
Small engines have to work hard...too hard... they have to over come the ci deficit that it has stacked against it.
Put a crank in a 340 or 360 and it'll make 500 hp by accident and it'll be at half the price..
