360 TrueStreet Magnum Build

Its been awhile since I've posted anything useful or remotely interesting. I recently acquired a 360 Magnum core that once resided in a Jeep Grand Cherokee, at least that's what the guy I bought it from told me. I never say no to a 360 core if its the right price and not too far gone. So after sitting on it awhile trying to figure out what to do with it I've finally settled on a plan.

The plan is to build a really nice mild street engine on a fairly tight budget using as many of the OEM parts as possible. The goals are maximum bang for the buck on Canadian pump gas whether it is 87-91 octane also keeping an eye toward excellent street manners (driveability) . I would rate this one as 99.5% street .5% strip. Truthfully I don't know what to expect as far as HP production goes but I feel 360-380hp and a ton of off idle and midrange torque is fair to expect.

Parts: '99? 360 Magnum block
360 Magnum crank

I know this sounds really boring but I am honestly intrigued with the sum of these parts.

Here's a shot of the block being rough honed. J.Rob

I ended up with a bit different cam than your build, it’s still a lunati roller part number 20200212... one thing I learned is roller cams are not cheap in Canada
