Hi everyone ive got a question about running a 280/280 original factory skoda camshaft that is from a skoda 120S race car from 1971. I am planning to put into my built favorit engine that goes as follows:

-136B favorit stock bottom end

-Felicia slightly ported and polished head with stock valves and stronger valve springs running a full set of aluminium pushords with reinforced tips (compression should be around 10,8:1)

-lightweight flywheel (4,9kg)

-stock favorit dizzy

-standard Pierburg Lekr (mechanical secondary done and rejetting are in the works)

-gr.A air intake and gr.A muffler

- 4-1 exhaust manifold with stock mid pipe

- stock 4,167 final gear 135 transmission

Now the question is this is a viable street camshaft and did anyone run a similair setup i am wondering about the usable RPM range on this setup with these cams and how it behaves in lower RPMs. Would be driven on the street and the occasional local trackday or event.

A lot depends whether that 280/280 is a race or rally cam - If race, it will be be very unhappy at low revs and will be 'lumpy' at idle (if it will idle at all below 1500rpm) to say the least!

sorry to specify its a factory rally spec camshaft for skoda 120s rally cars that raced during the early 70s mine came from a 71 make rally car its def a 280/280 since it has a factory serial number stamped at the end of the camshaft. Honestly i dont mind losing a bit of bottom end RPM and i wouldnt mind crusing at 2000 to 2400 RPM on the street or suffering from bad fuel mileage since its not a daily more of a weekend or when i feel like it kind of a car.

In that case, it would probably make a pretty decent street cam and would probably not lose anything at the bottom end of rev band - I was unable to find any significant data online for that cam.

10-248-1152 is the serial number
