always ask yourself how you plan to use the vehicle when you buy a cam. There is nothing worse than having a race engine in a street car that will be driven easy. Likewise, if someone plans to occasionally go to the drag races, who wants a cam designed to drive around town. 298 degrees is a lot of cam unless one plans to use it.
Here is what Webcam says about their 288/300 split degree camshaft
| Quote: |
| Designed for large displacement racing engines. Works well in a off-road application. Great torque! Requires Exhaust System, High Compression Piston, Performance Valve Spring Kit, and New lifters required. |
Here is what they say about their 290/290 camshaft
| Quote: |
| Strong mid and upper end performance for mild track engines. Requires Exhaust System, Performance Valve Spring Kit, |
so sit down and realistically decide how you want to use this car before you commit to a camshaft change, and you will be much happier with the final result.

Thanks for the advice, I bought the engine with the cam and being in South Africa cams are not easy to come by and if they are they fairly expensive.
It going to be a daily with the weekend warrior race night. |

I have this same cam in my 1915cc and it is made for turbocharged engines although I don't have a turbo on mine yet. There is quite a bit of overlap with the valves I've been told this is good for turbos.

It's a good cam for what you want to do.
Usually 9-1 compression is recommended.
Your heads could be better, but the cam is ok |

I CC'd the heads and they are sitting around 50cc and I'm hoping for a 1.4mm deck height to at least get me to 8.5:1 compression I might have to flycut the heads if we don't get that comp ratio |

| Since you already have it apart for rebuild and cam install would it not make more sense to deck the case or trim the cylinders to get the deck height closer to 1mm? That’d put you at 8.9 in and by itself. Then you could take a less aggressive cut on your heads to bump it to 9 if that .1 added is crucial enough for your build. |
