So I've started my engine build and have the engine mocked up to measure the deck height. My preliminary measurements are around .030. I've got to do some juggling around of components to get them more equal to each other. Here's what I've got:
head volume: 58.2 CCs bore: 96mm stroke 71mm Based on the cam I'm using here's what I get for different deck heights: .040 static C/R 8.84:1 dynamic C/R 7.76:1 .050 8.63:1 7.57:1 .055 8.53:1 7.48:1 .060 8.43:1 7.4:1 The engine is going in a 914 (obviously) that will be used for spirited street driving. I have 93 octane gas available here. The car will be driven between sealevel and 1000'. I'm using webers with SSI H/Es and a Bursch muffler. |

Stock rods, 6000 rpm max?
I'd do it. |
