Your current TYPE IV set up, Tell me what you have and what you think about it Options

[Hine62]

I'd like to know what some of the members are running for a type iv. Please answer the following questions:

1. What is the stroke, bore, and CC's of the engine?

2. If the engine is stroked over 71mm what case work was needed?

3. What cam are you running?

4. If using carbs/EFI, what is the setup?

5. What's the HP, or do you feel the engine has good torque/HP for the setup you have?

6. Comments on anything else...

Lots of great information. It looks like the 2056 is the most performed up grade. With a 71mm crank the case doesn't need to be machined.

@Dtjaden Did you install the megasquirt? How much did you spend?

Yes, built & installed the Megasquirt. Spent a lot of time on the wiring using Delphi Weather Pak connectors including bulkhead connectors. My startup with the megasquirt went smoothly, first FI and then ignition. However, it is not for the faint of heart.

Tuning takes patience, a lot of reading of documentation and time spent on the Megasquirt forums, and a methodical approach. I still am not satisfied with the cold idle and some transitions areas but it is still much better than the dual Weber 40 idf carbs that were on the car before the rebuild.

Megasquirt (MS3X) cost including the wiring, Innovate AFR, injector rebuild, sensors, etc. was around $1,000.
My next step is to spend some time on a dyno to do fine tuning. By the way, my final compression ratio was 8.8:1.
