I received my cam today from Web Cam [nice stuff] and it is a "stock grind" [new]. I thought I was getting their other version for stock fuel injection.
The only upgrade I am doing is euro pistons [flat top]. Is the stock gring OK or do I get better performance from the other version...specs are: .426 262 224 73 Here is a photo of some of the parts I have so far. The pistons are AA. They look OK to me. The cam to the right is the old one. Peter 1974 2 Liter Attached image(s) |

Jake hates the stock grind, yup. But most of the original 914s seem to run for 100K miles on the stock cam... Some have dropped seats, but many more have not. I know of one 2.0 that went for a quarter-million miles before being rebuilt! I don't know why some last and some don't, though. Probably has to do with how hard the engine is used and how well cared for it is.
...Of course, all it takes is one set of heads burned up and seats dropped to really ruin your day. (Not that I know anything about that! ...Three times over.... (IMG:style_emoticons/default/rolleyes.gif) ) Some people have had problems getting a smooth idle with the #73 grind (or its near-equivalents) and the stock FI. Sometimes you can get a smooth idle but you have other mixture problems at other load/RPM combinations. There's a fine game to be played, and if you can get everything to a point you can live with you have won better performance, and (theoretically) a smaller likelihood of overheating the heads. --DD |
