I'm not seeing information in my online searching so far.
And if they're solid, what's the clearance spec? This engine is a fresh rebuild, and if it's solid I'm guessing I should be adjusting them soon.

If it is a 1959 car 235, it had hydraulic lifters from the factory (but mechanical lifters might have been "swapped in" later). If it is a 1959 truck 235, it had mechanical lifters from the factory (but hydraulic lifters might have been "swapped in" later). Here is on-line specification information about 1959 truck engines. Here is an on-line 1959 car specification manual - it is a very large .pdf file. By the way, all 235 engines had "pressurized oiling". The better description would be "high-pressure" oiling (as in all 1954 and later 235 engines). Do you have a 1959 Truck Shop Manual - the valve settings are in it? Here is a procedure for setting mechanical lifters. If you have a car 235, the valve setting procedure is described in the 1958 Car Shop Manual. Reproduction manuals are available; and, original manuals can be found on eBay (and, often via an Internet search). | | | | | Joined: Feb 2014 Posts: 319 Shop Shark | | Shop Shark Joined: Feb 2014 Posts: 319 | We're in Michigan visiting family now. I'll get the engine numbers when I'm home and post them.
thanks
BTW, is there any way to tell from a visual inspection? Any difference in the rockers or...?

The best way is to pull a lifter and inspect it. | | |
