That 351c 4V is an un-real engine . Very Powerful I would Like to see more of them being built . Not sure how rare they are these days ?

Well, they're rare, especially the 4 bolt block.... Expensive to build is about the only drawback, think that's what scares a lot of people away from them.... Even box stock they were a strong engine, but with some CNC and flow bench time on the heads, a light (or stock lightened) reciprocating assembly and they do stay together quite well at RPM.... Always wished their popularity would have been higher so the aftermarket companies would have tooled up some aluminum heads for them..... Roush used to do some High Port Cleveland heads that really helped with the flow on the exhaust side.... The way the centrifugal blowers react so well to good exhaust flow, betcha they would respond quite well to a blower (either roots or centrifugal) with about a dozen or so pounds of boost...... Don't remember the flow numbers on them, got it on a head sheet someplace in the piles and piles of paperwork and propaganda.....


PS--We ran the high port exhaust heads back in the late 70's on a road race car I crewed on for a couple seasons--for whatever reason they moved the power band down about a thousand revs. .... great power and no failures mechanically..... sure would like to find another set of them sometime!!!!
