The most common Honda misconception ever!

H = 123lb short block
B = 104lb short block
D = 100lb short block + oil pan

H trans = 96lb
B trans = 90lb

The fully assembled H series head is about 10 lbs heavier than a B-series totaling 35lbs more

A complete H-series will run $1,800 or so with another $500-1000+ to install.

I know where a 280whp H22 is just begging to go into a car but you can't get it for that price
