New to me 78 Tique

Had been looking for an older boat to go along with my 99 Sport. Saw a 78 Tique on craigslist this morning obo and thought it was too nice to call about. Thank you TRBenj! Tim, knowing I was looking for something, texted me and told me to get on the road. After speaking to the owner, my friend Jesse and I loaded up and drove the looong 1.5hrs to buy this beautiful 1978 Ski Tique (yes, I will fill out a diary soon). Jesse and I bought the boat together and hope to bring this beauty back to its original condition.

First up will be the engine and the trailer. Engine popped the freeze plugs in 2013 so we are on pins and needles as to engine...anyone know a good correct craft engine shop around the Carolinas? We are going to soak her this week and put a bar on it next weekend just to be cautious. 302 Commander.

Otherwise I am very pleased with the boat. New floor and carpet, solid mounts, and from what I can see, all parts there. Trailer has a little left to be desired but it trailered well on the trip home at 65 mph. Pics follow (people in pics are seller and son). Realize now that I didn't get any interior shots. Those to come. And to all, Fram is on there. Don't worry, will change. Thoughts? Let me know what you see is askew.

Questions:
Oil and filter...same as my GT40?
Anyone with pics of where these freeze plugs are?
