Let's Build a 416 with Cast Iron Heads and Manifolds
One thing is certain, the OP’s quest to get into the 11’s using a 435” SBM with W2 heads and exhaust manifolds in an A body won’t require any out of the ordinary wizardry to reach that goal.
Be interesting if it ends up going on the dyno..........and then down the track.
Two posters on this thread have already done it.......without the 435” or the W2’s.
Edit-
I forgot about the 4 speed and 3.55’s.
If you couple that with some repop bias plies.......it’ll def get harder to run 11’s.
