Worth the effort?

Well all three shop have all said it is NOT the carb and all have tuned it with the same result.

The engine is 3 years old and only summer driven. It was built by a reputable local shop. The bill states it was blueprinted but unfortunatly they never gave me any of the internal numders.

All spark plugs where out with the throttle held wide open and turned over for an equal number of compression strokes.

When run off the line from and idle or held on the footbrake and given some rpm the car will lay over and do nothing could call it a massive hesitation before it slowly pics up and goes. If your cruiseing its no problem. This car will NOT do a burnout it will load up and push against the footbrake and do nothing, even if you let off the throttle it will not even chirp the tires.

All in all its a gutless wonder off the line. Great in the upper RPMS but thats it. I've had three different shops all recomended highly by others, all racers in there own right tune this car with the same result.

Last year I was told the convertor stalled too low -IE: 2600- So I sourced out a new SMR unit who recomended 3000rpm stall and thats what I bought swapped the convertor with no change in drive characteristics and a 2500rpm flash and once again I have been recomended to "change the stall" I've had the original 340 when tired in the car act this way, had a 360 built by a shop that had TONS of problems but also also bogged. Now the 340 rebuilt has the same issue.

Beyond all that with nothing changed over the winter then the balancer it pings under WOT off the line now. Fresh fuel etc and no change.
