Indy 360-1 vs TFS VS W2

The machinist I use built a 420ish small block with a ritter block, big solid roller and otb victor heads. On the dyno it made 630 which seems like a good number but when you look at the heads and the work involved it was a bit shy of what you would expect.


Wow that’s way shy of what I would think and that’s dyno horsepower. Sorry but there’s something is wrong with that combo somewhere.
