I currently have a non-running 351w in my 66 coupe. I would love to rebuild it however I'm really considering a 302 just to have more space and keep the 351 cast heads. This will be a weekend driver and not a show car by any means. I sure loved the power the 351w gave me but the overheating problems and timing problems were gruesome. If I get a 302 what type of block should I get? Pre 80-s? Something newer. Roller cam compatible? The 351 will cost about $1900 to rebuild (I dont have the time or the skills). Any advice will really help.
