Opinions and advice, My 914-6 resto Options

So over this summer, I refreshed the suspension and brakes that are going on the -6. I’ve had a set of front suspension with delrin bushings, 21mm torsion bars, big aluminum calipers and -6 rear trailing arms with delrin bushings. It’s all repainted and ready to go in. A mild heart attack at the end of September and a triple bypass 6 days later postponed a bunch of work. I’m getting back to it cleaning parts for the winter project of building a motor.

I’m looking for motor advice. I want a small displacement screamer. We don’t have freeways on the Maine coast and it’s not going to be a daily driver just a toy that I will never sell. So, I am building this on a 914-6 case, not the original which I have, counter weighted crank with matching rods, 69S heads, 81 mm 906 pistons and cylinders with 40mm Webers. Which cams? I am looking for a willing motor with explosive ( for a small motor) revs from 4500rpm up to 7500. What does the group say? Our old track 911sc was a 3.2 with ge80 cams which did that but I don’t want that kind of power for a street car. What does the group say? 911s, mod S, 906, Dc60?

I hear E cams get nearly the same perf as S but do it more smoothly
I wish I could say from personal experience.
Happy New Year !

When I had the cams for our mostly stock 914-6 engine done by Dema Elgin he also recommended E grind. This is for spirited street driving. It has slightly higher valve lift than the standard 911T cam. If you go this route don't forget to adjust your cam timing to match.


I haven't put this in the car yet, nor do I have another car to compare against. I can only pass along his advice and specs. FWIW.
