Re: 460/429 or 351
Hi, its only the early b/block that put out that power. By 73 they were very low comp ratio and power levels were down.
But, a well built mild 460 with some alloy heads would make great power and be quite streetable.
The size and weight of the bigblock is the only downer. The good thing is they make power/TQ easily.
You could go for a stroker 351W, good power, plenty of room around it for good headers etc, and will still be great on the street and lighter.
For easy brute power, id go the bigblock.
For an easier fit and weight id go 351.
