I like the "erly iron", but here 'newer is better'.

If your building a custom light weight car, a built 250 (to the 270+/- CID) is probably much lighter ("More bang per pound".) than any other. ;\) One horsepower per CID+ "no problem".......

Check with Larry/Novaman/twisted six for exact info on this.

Good luck. \:\)
