So call me crazy but I?ve sold my Stock eliminator 1970 340 Cuda and going on an adventure that I?m kinda excited about,have purchased Danny Wilson?s 1974 Buick Apollo J K L/SA stock eliminator car out of Illinois from another individual that bought it out of his estate,past owner has gone 3/10 under,looking for recommendations on the go to guys for these Cyl. Heads and how good are these cranks, blocks,can you take them .070 over safely or as I suspect a sonic checker needed? Thank you in advance?Chad

Chad, We went .060 over , no fill with my 75 car. It ran okay .
No fancy crank ,and it was fine, until it busted at the first journal . No telling what caused it. Replaced it , and it lasted until I sold the car, anyway.
Dave Layer did my heads. I got the "medium" job.. LOL They might be familiar with the Buick heads out there.Worth a call anyway.
The oiling system takes a bit of attention on Buicks.
You can call me and I will tell you what I know about them.

I'll just call you crazy and leave it at that LOL, loved the Cuda and good luck with the Buick. I talked to Alf Wiebe a while at the Woodburn Divisional; sure he knows quite a bit on them and likewise I'm sure he's got an inside info line to Jason Line.

Contact Gary Herche from Indiana, not sure he is still doing engines , but he would be great for you to talk to about Buick stocker engines that is still a very good combo at 266hp pretty easy to get one to 1.00 under
