So here we go again with this ford 460 If i get on the highway when it is cold it will usually make the shift point at 5500 w/o missing a beat, but as soon as it gets up to temp 185 degrees it starts to pop and miss pretty bad. Engine is running a edelbrock 750, straight from the box, adjusted both screws for highest vacuum reading and then reset to make each equal as edelbrock said to do. Engine is 71 block, d3ve heads,edelbrock intake, headers, 2.5 in exhaust to 3 in stacks, stock duraspark 2 system, all new including new accel coil, stock ignition control unit, and cap and rotor, wires are accel as well and im running autolite xp25 plugs. i have a holley 140gph fuel pump mechanical, removed all electric pumps in tank, and im running a holley pressure regulator set to 5 psi as the edelbrock. I run 50psi oil pressure when at temp of 185. Engine is stock elsewise, Checked compression from 1-8 here it is 155,150,145,150,150,150,145,150. vacuum reading in at 20hg, timing is as follows all in at 3000 and is 36 degrees, 26 mechanical and 8 degrees initial, i have tried 10, and 6, with no luck as i said in the beginning if it is cold it seems to not do this. The way it acts it seems electrical, just not sure where to start and what i should look for. Fuel pressure does not drop and this will do it from the beginning, if you have it in park or going down the road if you bring it up fast or slow to 4000-5500 rpms it just runs like ****. Vacuum advance is currently plugged and disconnected to test for timing issues. Any ideas?
