For those of you who want the light weight with the mag case engines.

I was told you had to spend some serious money to up grade my 2.7L mag case to make any horsepower. This was when I was cutting every pound to reduce weight. Therefore my decision was to go the 3.0L aluminum case route. I was told head studs where about the only problem. The cam I was having custom ground would be lower than normal torque peak as that's what you need to pull out of the corners. Mike Bruns and I decided the later 3.0L (mine is an 81) with the smaller intake valves, would work fine where I'm not looking at 7500 + rpm to get any power. The torque peaked at 4800rpm and horsepower at 6900rpm.

So far I've only had one over rev, I have a rev limiter on both ignitions on the twin plug MSD set at 7200rpm. However I did miss a shift going into 5th and got 3rd, shift linkage had loosened. I saw the tack go to 8000 even after I de-clutched and took my foot off the gas. Coasted back to the pits. Ran it a few more times just enough to turn 3 then 4 thousand with not problems. Called Mike, he said pull the lower sump and see if there's any metal on the magnet. There wasn't. Mike said remember we built the engine to turn 8500 even though your power band is much lower.

That was 3 years ago and I've never had any issues since. Build your engine to be bullet proof and then drive the s**t out of her!!!!!!!
