So new engine build for my 170 Boss bronco, hahaha,
D2 250 block, knife edged ballanced crank
Ballanced rods, and pistons
2.3l hsc flat tops .030 over
Head milled .045"
E0 hex log, 60 hours in port and Polish, mostly in the log and the exhaust ports, pollished combustion Chambers
Should be 9.27-1 comp
Erson rv10h 280/280 cam
Dsii dizzy stock to E0 specks
Ford "e style" 68,000v coil, AAP 45 iridium spark plugs, 1969, pre smog timing set on the cam
Motocraft 2150 1.08 on vi adapter, not direct mount. 195* thermostat 4000' elevation.
Actual deck hight is .137-.139"
I set initial timing at 10* and it runs ok, it's flooding every time I shut it off...... I am switching to a yfa carb tomorrow, have to redo all the linkages again, but it just doesn't feel right, no hessitation on hot restart. But it diesles when I shut off, and at places in the rpm curve it has mind blowing torque, bit it comes in and out of it???? Should I be setting intial timing at 8*? 12*? 15*? , Any mods I should make to the yfa before I put it on??? It's a nos calibration is 76 Maverick 4.1L 49 States. Open to suggestions, I feel like if this thing ran consistent, I could smoke 35" tires and get 18-20 mpg....... Thanks in advance!!!![image]https://photos.app.goo.gl/7ZN97Jgdfbx4WBgu9[/image]
