Hello fellow LS lovers, I am new to the site but eager to learn more on swapping these engines in older muscle cars. I am currently restoring a 67 Nova 2 door sedan with a Heidts mustang 2 frt end and Ford 9" rear and want to make it pro touring. I have lots of questions for you guys and thankful for your experience and help. I am looking to put an LS1 with 4l60E in the car but have been confused as to which one would be the best fit for the car I am having issues with the engine oil pan and belt system clearances etc; any help would be highly appreciated.
Thanks and good being here, BOBLS in Florida
