The junkyard website has the following number noted down as “manufacturer code”
300-08159 If that means anything, the engine was pulled from a Grand Cherokee Limited and is the original engine for the car. I will get new up to date pictures of the engine lifted from the body.
Would 383 do it or is 408 the only size that's even close?
What are the reasonable max rpms of the stock 360, a 383 and 408 stroker?
