Hi
I have been restoring my 1967 coupe for a number of years and part of that was swapping the SBC that came in the car to a Pontiac 400. I bought an engine from a guy who had it built by a reputable specialist in the UK. I had not heard the engine run until I fitted it in my car, Everything looked good once I got it warmed up and timed up. I have only had it running on the drive as the car is not fit for the road yet. after 20 min of idling on the drive the engine stopped. At first I thought it was a fuel problem but when I tuned the engine over I noticed it is making no oil pressure and as I have a fuel safety switch to an electric fuel pump if there is no pressure the pump will not turn on. Before this the engine had really good oil pressure and was running ok with no smoke or knocking noises.
Any ideas what to check for, is there a way to check if the oil pump is working ?
Thanks
