eltorito - VSpec or not, an engine has to have compression to run at all, it just might not feel as tight as other motors.
Totally agreed with you. Have ran Picco, Hyper, O.S., R.B. &
Nova Rossi engines & once there's no compression you'll never get it to idle or respond instantly.
Is it true from some guy running a CMB .21 off-road engine
that when cold this engine is totally not tight, but when hot
it will be tight. Seen him race & it keeps flaming out after
5 ~ 6 mins run-time.
