Another slow 340

Door #1
Get rid of the orange box, it's retarding the timing 8* starting at 3200 RPM and by 5200 it's fully retarded. The chome and gold aren't much better especially if your street driving the car. You've got the MSD so use it.

Think about that main body on the carb....replace a decent Holley main body designed for the Carb with a Chinese copy....think about it. Have you cleaned the carb...10 years of sitting it's bound to have issues. Rebuild $150.00

Throw a set of Caltracs on it, it's like adding 2" of tire. $339.00

Change the valve springs $80 - $130.00

Get the distributor recurved correctly. $69.00

Look at the Stewart Warner programable digital tach and shift combo, small simple and deadly accurate $149.00

I assume your referring to the Holley or Carter 120 mechanical pump, check your fuel pressure, if it's been sitting for 10 years the diaphram is probably stretched out or rock hard, a simple fuel pressure test will tell you, should be at 6 PSI. Whether it's good or not you need to drill out the 1/4 NPT inlets and outlets to 3/8 NPT and put the proper sized fittings in it if you want it to flow anywhere close the advertised 120 GPH. Inadaquate fuel flow will cause that high speed miss 2 Fittings $10.00 or less.

Get more power to the ground, add the Caltracs Mono-Leaf and their front and rear shocks. $600.00

Gears at least 3.91 even better would be 4.10/30 depends on how much street driving you want to do. $250.00?

Convertor-Dynamic 3500-3800 $395.00

It's all pretty simple, it just takes money.
