"sounds like you did more than just the rockers"
So when I got the car in 2006, it had a tired mid '70s 302 in it. I was able to locate a complete '68 J-code 302 to install. The date code is even pretty close. To begin with, my goal was to return the car to stock as much as possible and then show it in MCA Occasional Driven Class. When the engine went in the car, it was concours assembled and detailed. As time went on and I found that I longed for additional performance, I elected to use some simple bolt-on mods to make the car more enjoyable and reliable, as it gets a lot of use during the late spring, summer and early fall here in NH. However the decision to upgrade the cam/lifters/valve springs/rockers was made early on, and those parts have been in the engine since the rebuild. As for the rest, nothing ridiculous though, just small upgrades that would be easily undone if I ever change my mind again. I retained all the stock pieces (carb, fuel pump, valve covers, air cleaner, exhaust manifolds, etc) and they are boxed up and put away for safe keeping. I'd estimate the engine is making a reliable 275 horsepower and that's all I need. It's been all over the Northeast and I find it very reliable and a blast to drive. As stated in a previous post by another, don't skimp on the quality of parts.
