The 460 rotating assembly in a D1VE block with TRW L2443's and C8VE heads will put you at about 13.25:1 compression ratio. If you zero deck the block (and ideally you should), you will be nearing 14:1. Is this for a drag car? If not, then you will need to lower compression. You can barely get away with 10:1 on pump gas these days.

I assume those camshaft specs are advertised duration and not duration@.050" If this is the case, then I would say that you will have too much compression for that camshaft. If I were in this situation, I would zero deck the block and also 1) get a camshaft that better suits this high comrpesison build, or, 2) cut down the dome tops of those pistons so as to reduce compression. Which way you go depends on the application of the motor/car. By the way, it is not necessary to whack the entire dome off if you don't want to...you can leave .100" remaining, etc. and get a desired compression ratio.

The C8VE heads are outstanding factory iron heads. Don't go with the CJ valve, as the valve heads diameter is too big for the passrnger car size intake port and shrouds flow, particularly at lower lifts. Stock passenger car valve size is 2.08" and SCJ is 2.25" Better to use the PI 2.19" intake valve with the C8VE, C9VE or D0VE heads.

The factory 460 crank is very strong. The 2-bolt block can work and more importantly can be strengthened if needed. More on that later. The weak link in the bottom endos the factory rods. They HAVE TO GO in such a build. Don't use them.

Some bigger single 4-BBL intakes may help your off idle/60 ft times over the tunnel ram (on a 460), but again depends on what exactly you are building/trying to do with the vehicle (application).

Need more info on intended use.
