How do you like your 451? I have been contemplating doing a 451 build. I have a spare 400 block as well as another complete 400 engine, a 440 steel crank, and a couple sets of 400 and 440 connecting rods. It would be fun to build something on the side to swap out with the 400.
I love the 451, I’ve had it together almost 23 years. It is obviously an old tech stroker build. LY rods, 440 crank, KB pistons. 452 heads, M1 intake, MSD ignition, etc.
Things I would do differently now if building a 451 (I was in my early 20’s then)
Better rods
Cut the block for the crank not the crank for the block.
If I were gonna build a stroker 400 today I’d just build a 512.
