Stock 5.2 Vs 318 with XE262

Ok then where did I see "stock 89 block" at?

I am currently running a stock 5.2 magnum in a D150. Headers, Carb, Port matched.

Just finished building a 318 with XE262 Cam. Stock 89 short block, port matched.

Do you guys think the 318 with the XE262 cam will make more noticeable power compared to the stock 5.2?
