273 commando Build

I have approx 60 miles on the commando now and it has more torque and hp than last engine . Haven't taken it over 4500 rpms yet , but it really feels strong . Revs real fast , has a totally different sound than last engine also. Compression "Does" make a difference !

LOL, It is all in the combination and tuning. And it sounds like you have that nailed. Nice Job!
