273 commando

Depends on your definition of satisfactory, the commando is rated 10.5:1 but comes up short, open chambers will drop it some more, will it kill no, but you'll lose a bit.

I plan on driving this car everyday weather permits.
I'm gonna use them put 340 size cam and 4bbl fi.
If it doesn't work I'll change it.
Thanks
