I'm new to the porsche game. I have a 73 with a 1.7l. It all was in a box. I've had experience with Type 1 bug motors but not 4. I have bought the weber progressive carb kit, planning on ordering the svda 034 from hotspark. Is the camshaft a big issue since it was an injected motor? Any info will help. Thanks.

914's are sickness you will probably never recover from.

I don't think your cam choice matters much if you are going to use a single progressive carb on a type 4 engine. The single progressive carb does not work well on a flat 4 engine. The fuel drops out of the air flow at low engine speeds and collects in the intake runners. You end up with irregular mixture and poor driveability.
You are better off with FI or dual carbs.
If you go carbs and stick with the original FI cam you will be leaving some performance potential behind.

If you spend some time searching thru the site here you can find a lot of threads on cams, carbs, FI pros and cons.

Good Luck

Jim
