D-225-55) BASIC RPM 2800-6500 I'm going to have to disagree with you on this one mate for a couple of reasons. If you read the Crane description carefully this cam is for highly modified engines with high flow heads, headers, exhaust. The only headers legal in California are shorties which flow no more than stock LT1 manifolds according to all reliable sources. Number two, notice Crane says it is legal for "Listed Applications, 94 and up", those are MAF cars, Andy has a 92 which is a speed density car. Speed density cars require much more in the way of tuning when the cam is changed because the fuel program is based on a stock engine and the manifold pressure the ECM expects to see relative to rpm and throttle position. (The ECM adds fuel based on lower manifold vacuum assuming load has increased) MAF systems on the other hand measure air flow directly so they can adapt to changes in manifold pressure caused by cam change with less difficulty. I don't think this cam will help power without the heads and long tube headers or pass California emissions. |
