Re: Building the ultimate 3.5l motor

Talk to John Dougherty (drcamshafts.com) about cams. 12:1 seems hard to do with Carrera heads, I guess it will depend on your planned deck height. I would probably run about 10.8:1, any cam like the Supercup, DC20, etc., build pretty high dynamic compression ratios.

Is your ITB setup 45mm at the head port?

Keep in mind the displacement increase will make the cam seem a bit milder because the 3.5L engine is moving more air overall at a given RPM (vs. 3.2L S.S.). Not to mention, the 3.2L 74.4mm-stroke crankshaft will lend itself better to low-end torque production.

Sounds like fun.
