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... Hine62 |

Home rebuild of a stock '76, FI 2L.
My crank was bent so I bought a counterweighted stock crank from Rimco and balanced the rods, flywheel, etc. I think the counterweighted crank is smoother @highway speeds than my stock 1.7 and a '70 bug I have. AA flat top piston, cyl assemblies. The stock pistons were dished so the flat tops give a little more compression. AA parts need to be measured and matched... HAM rebuilt my heads and I bought a Raby 9550 cam kit. Used Jake's video to put it together (but remember the oil sump baffle..tray..thingy...) Pertronics II and coil. It has plenty of power for me and pulls nicely thru a near stop in 2nd gear. I get 30/35 mpg. Highway speeds of 75 -80. I've had it up to 125 indicated with stock/tall tires. My head temps run 275 to 325, sometimes 350 if there's a head wind. Oil temps are around 200 this summer with a cooler in the deck lid. I'm going to take it off this fall and see how it does. Rimco and HAM were good to work with and the Raby cam does everthing he says it does. The ignition hasn't failed yet. I can't wait to do another one. I'll try a 2056. Good luck |
