COMMANDER370

I am going to be using a Comp-cam 270 magnum in my 1980
L82.Also will be using Weiand stealth manifold and Holly 4160-600 CFM.
Anyone using a set up close to this? Car has been setting up for the last 12 years,so i figured it was time to roll it out and make some noise.

I had a Magnum 270 and it is a fine cam to go with the 600 CFM Holley and your intake although I used a performer. Not much diff between the weiand and edelbrock. If you are planning on running the stock heads with this then you chould check if the valve springs are ok. I seem to recall that new springs were required to work with this cam.

If you haven't already throw some headers and dual exhaust on there and boy she will rumble for sure!

Got new lifters,springs and timing gear set.also have got flow-tech headers. a friend of mine owns muffler shop and will furnish new set of duals at his cost.

For our 75 L-82 we dumped the 76cc smog heads, added WP Sportsmans w 64cc's, CC Xe268, roller tip rockers,RPM intake, "worked" dist, headers 2.5" pipes, and Lars Q-Jet.
The engine runs a lot better then the 75 stock pig it was. Will slap on a Holley this summer to test it. Maybe dump the crappy chambered pipe exhaust for flowmaster 40's, should be over 400hp at the flywheel. ( I really hate chambered pipes)
