I have a 1968 210 HP Chrysler in my Barracuda. Should the engine be at operating temp to adjust the valves or should they be adjusted cold. Thanks ,Jim B.

doesn't really matter. if you just installed them then you really don't want to wait for it to warm up before they are adjusted.

The manual says the intakes are .012 and the exhausts are .022 tappet clearance with the engine at normal operating temperature.
Page 32 of the " Chrysler Marine V-8 Engines" manual in the reference section of this web site.

The manual calls for adjustment every 50 hours, although it does not say, I'll a$$ume solid lifters. All of this info is for the M series (polyhead) Motors, the later LM series may be completely different. The odds are that a '68 has an LM motor.

The '68 would be the LM engine like Gary said. They made the switch in cars in 67 but some early 67 CC's still have Polys. Both are solid lift up until '69 or 70 I believe, as I know we had a '68 which was solid and a '70 that is Hyd.

Thanks for all the responses,the engine is indeed a LM318,210HP. From what I have read in the manual that I have ,the 235HP version of the LM318 had hydraulic lifter and required no valve adjustment . I do not have a manual that specifically states wether or not the 210HP version (a$$ume solid lifters because of the adjustable valves /rocker arms)should be at operating temperature or cold for valve adjustment. One other question, I run my boat in fresh water only, should I replace the stock 140 degree thermostat with a 160?Thanks for the help! Jim B.

After reveiwing all of the information I could find on the 1968 Lm-318 Chryslers, I have come to the conclusion that the valve train on the 1968 210hp version(solid lifters,adjustable rockers) must have carried over from the 1967 M-318 polyhead. The 1968 LM-318 235hpversion incorporated hydralic lifters and non-adjustable rockers. One of my manuals is for a LM318B 225HP version(hyd. lifters,non-adj. rockers), but the manual is not dated. I assume this must be a 1969-70 version of the 1968 235HP model. FYI. Someone correct me if I am wrong . Thanks ,Jim B.
