i'm planning my next foolish car project, and i've got to decide if i'm going to use this engine i have. it's a Navarro-built Rambler six that i bought as a load of parts 7 years ago.
the issue is that block and head are both cut for o-rings. see pics. my question is, is this suitable for durable, long term reliability in a street engine? i have plenty of o-rings for it. i have zero experience with o-ringed engines.
i plan on a mild build, carbureted, normally aspirated, cam undecided (streetable), relatively high revs (this engine was run up to 6200 i believe). turbo would be something for later.
the head is unique, a factory "R & D" casting (R&D part number cast in, not a production item) that has has substantial porting. the block was bored and sleeved, to reduce the 199" displacement to 182" for the car class (67-69 Indy).
