Will a olds rocket 350 fit in my 1986 chevy camaro it currently has a stock 305. How much more horsepower gains will I get and do I need to modify anything to make it fit. Tell me everything I need to know about this swap

1. It's an odd-ball swap, nothing from the factory will make it fit, and it is completely unsupported by the aftermarket.

2. It doesn't make a lick of sense beyond being "something different" ("I'm getting the engine for free" doesn't cut it).

3. It is occasionally discussed (such as on May 3rd).

4. Everything you can learn will be found with a . Everything else you're going to have to figure out for yourself.
