Second season on my 2056 with 9590 Raby cam and heads done by Len Hoffman. Stock L-jet injection.
When I run the car up to 5500-6000 rpm it cuts out like there is a revlimiter (which there isn't) or the valves are floating. Could this be an issue of the L-jet injectors not supplying enough fuel at those conditions? |

The distributor is pretty good as far as wiggle I went in and cleaned and relubed everything when I was tuning the engine and used the better of my two distributors.
Coil is a Bosch blue but I don't know how old. I have read some recommendations of switching to a pertronix or MSD don't know if that is just coming from the manufactures or resellers. |
