I'm thinking about taking my stock 1.7 to a 1911. Some old threads seem to suggest that you can't do this with the 1.7l heads, while others seem to suggest it's fine. Can anybody set me straight on if I would need new heads, if they'd need to be machined, or if I'm good to go?
Also, I've got 2 engines all with original german cylinders. Am I better off taking the best 4 and boring them out or going with new chinese cylinders (local shop recommends QSC). I've been thinking if I've got 4 decent ones that the OE cylinders would likely be better than the chinese stuff. anything else I should be thinking about? |

QUOTE What type of carbs did you run in that set up? I don't remember what it ended up with. Once the heads left my shop I lost track of what they ended up using. The customer feedback came to me months (maybe more than a year) after I did the heads. QUOTE My dad has a 1911 in his 914. Len did the heads. They are 1.7L with 42I 36E. It is 9.0 to 1 and has a Raby cam in it. Not the 9550. He is running 40 webers with stock SS heat exhangers. It made 95whp and I think 105 wtq. It is a good engine that is not expensive to build. Yeah I know your dad is really happy with that engine. And it is a pretty affordable, reliable, easy upgrade. |
