Best year to pull 360 from?

IMO, the debate is really....do you want a LA 360, or a Magnum 360.

If you take my advice, you'll find a 89-91 LA Roller Cam 360.....for the benefits of the Roller Cam, 308 swirl port heads and simple parts interchangeability.

From the factory, the 89-91 360's have 8.5:1 Compression, and good flowing cylinder heads....untouched internals and the addition of a Edelbrock Air Gap 340-360, Holley 750 Double Pumper, Headers, and you'll be looking at about 280 horsepower to the ground.....add in there a custom grind Roller Cam (in the neighborhood of 264*-280* duration and less and .500 lift), some port work, and tuning and you could get over 350 to the ground pretty easily and run on pump gas.

The Magnum followers will be in here shortly to tell you the advantages of Magnum 360's.....I just dislike the special intake manifolds, and the special head hardware...otherwise they are very similar engines.

Good Luck!
