I have everything except pistons for the 3.58 crank into a 340. I’d love to get started on mine now, but, there’s always something in the way. (LOL - groooooan)
I do like that combination of the increased stroke and big bore.
Just personal opinion if bigger displacement is better hard to beat a 400 stroked and built. Heck I have a 360 roller lifter engine out in the weather seasoning I say let it rot
Are you going to build the 360 or just let it rust beyond use? I had a neighbor that left his 302 out in the weather to long and it took a 0.060 over bore instead of the 0.020 or 0.030 what a waste of a good 302.
