3.3 Turbo case

[Bobboloo]

Question. Can you use a 3.0 (70.4mm) SC crank in a 3.3 Turbo case?

I thought that you needed to use the 74.4mm crank that was used in the 3.2 Carrera and 3.3 Turbo motors.

I ask because of a motor that is for sell in parts has these two items in the package.

I don't have Wayne's engine book in front of me, but you should be able to determine if it will fit by checking all the crank and case diameters.

I don't think you can. The #8 main bearing journal on the 930 crank is 40mm . The #8 on the sc crank is 31mm. Could you have a75- 77 3.0 turbo engine? Dan
