Stock stamped steel ones. 1.5:1 ratio. Based on the responses, sounds like my original gut feeling of just running it unshimmed will be just fine. Thanks all.
Dial indicator on top of rocker arm right at the pushrod. I started with the rocker shaft tight and slowly unbolted. I also reversed this and checked it as I tightened it. Engine at TDC compression stroke.
They can use the same lifter but there are magnum specific ones too from what I found.
With non-primed lifters at TDC I have .125” of preload and then I can take my thumb on the rocker arm and compress the lifter another .095 to .105” so I’m right in the middle of the lifters’ range I just...
I have an 89 roller cam motor. I’m getting .125” of lifter preload on the new build. The new lifters have over .200” inches of travel so I’m in the middle. I know the magnum engines run .120 or so I’ve heard but is this okay with the LA 360 considering the lifter range?

I looked these pistons up. Thank you, I think this is a better fit for sure. So at 9.5:1 and a mild cam, is 89 octane do-able? Really trying to keep him from having to run 91 or 93, just because of daily cost for him.
Thank you. As for the timing cover, is this just because they are so readily available or is there a reason not to do the machining? I do have the proper tools and know-how (that sounds cocky, I don’t me it that way) and feel it’s a good learning experience to teach my son to work with what you...
The only thing I did find during the tear down this weekend was a very shallow pit mark on the crank mains 180 degrees from the oil passage. I’m not sweating this. I think we can run standard bearings and this mark is in line with the relief of the bearing. Hoping to just polish the journals but...
Well just came in from taking a closer look and using a brass wire brush on them. I can’t see any signs of cracking at least to the naked eye. Here’s hoping! The only head issue now is I have 3 exhaust manifold bolts that decided to become a two piece design during removal. Planning to just mig...
Awesome. I’ll look into those pistons. You think 89 octane would still be do-able with 9,5:1. He’s a high school kid and has to feed the fuel tank. We’ll get the replacement valves and go from there. I didn’t like the idea of cutting the seats either. I appreciate the feedback on the HP. I...
Man,
99 views and no opinions? Just kidding around, but I would appreciate any info. I'm hoping to get the block and heads dropped off at the machinist some time this week. If anyone has any input, I would greatly listen!

My son picked up a factory 360 LA roller cam engine. We're doing a full rebuild, swapping to a carb and putting it in an older W150 truck. He's planning on running a CompCams 210/220 Hyd Roller ram with the stock roller lifters (good shape and we have a budget) The truck is lifted on 35" tires...
Well,
After 4 pages of great advice and discussion.....he just picked up a 360 for a V-8 build, LOL. I mean, it makes sense dollar for dollar, plus he has a small block bellhousing just laying in front of my garage. I do appreciate all the help. The slant will be hanging out for a bit. We might...
