Ok guys, to catch this up, the displacement issue has been settled, it will be a 4" stroke combo. I dug around in my core pile and found a early 71 360 block that was std bore. Its currently in the ampro for baking and blasting. It will get the full treatment, including bushing the lifter bores, and all the other tricks. I am going to do standard LA heads as a group first, then possible the offset rocker stuff later. I need to keep the same intake, carburetor and headers for all the tests. A number of great members have reached out with ideas, and offered heads for testing, I will keep this updated as we go. Thanks for all of you guys input!
