340 X heads

Was last run 25 years ago. 3000 lb 73 dart sport 10.60s. It’s a 340 with the 11 .5 forged TRW pistons. .600 lift roller cam. 273 crank and rods. Kim

Couldn't possibly go that fast with open chamber iron heads, heavy pistons, and old school cam, and not even a stroker crank!

Kidding of course.
