My engine is a stock (big port) '78 SC 3.0 from which I have removed the CIS injection. I have purchased some Weber 40's with 36mm venturis and manifolds that have been ported to match. I'll also be running some 1 5/8 headers (I know, they may be a tad big...)
I have been getting a lot of flack from a buddy for not re-camming the engine while it is a long block and out of the car. He claims I am leaving around 30 hp on the table by not stepping up now and doing it.
The car, at this point, will be strictly street driven but I would like to maximize torque and street/canyon potential. I have never driven a 914-6 before, so I really don't know what to expect if I don't cam it.
So two questions arise. Which would be a good cam grind and how much should I expect it to cost?
I see Porsche has some stock grinds, and others (like Elgin) grind cams to various specs. What would be a preferable cam design for this setup?
What are parts costs alone?
If I brought my long block to a reputable shop what could I expect to pay for labor and ancillaries like cam chains, gaskets, etc? A ballpark figure would be OK at this point.
Has anyone here done this specific upgrade from an early 3.0 with CIS to Webers, either with or w/o cams?
All feedback is appreciated.
Thanks.
