About Van Expertise I have been maintaining a fleet of approximately 55 light, medium and heavy vehicles for over 20 years. Most are 4X4 pickups and off road fire fighting trucks. Some medium duty trucks. Some military light trucks.
I can answer most questions concerning 4X4 engine, drive line, suspension, electrical, and fuel, both diesel and gasoline. Ford, GM, and Dodge, old and new, but prefferably not newer than 99.
Question Howdy, I have a 1987 grand nat. The engine runs good with power and acceleration up to 55-60 mph and then looses power and bogs down. I can stamp on gas but it just dosen't accelerate. I let the car cost and let it get down to about 40 and the engine seems to respond and I can accelerate only back to 55 or so. We looked at what we think is everything. What about timing?
we are running a edelbrock 500. Metering rods?
distributer? This has a few of us going nuts. Any suggestions? Dave
Answer Hi Dave,
On your fuel test....if there is plenty of gas there, might advance the timing a little.
If that carb has the little filter in it where the gas line connects, and it is the paper filter with the rubber check valve, make sure it isn't in backwards.
