Anyone else running a Olds Rocket?

biglou55, in reality, the BOP big blocks would be pretty much the same as slapping a caddy engine in there. (and your engine parts would be cheaper too) The exception would be the location of the motor mount towers, and possably not being able to use the ones I used. (being that they are flat, I say it is a good starting point.) Just take a look thought my caddy engine swap page (In signiture) and see what's involved.
Use your 455's manifolds, don't even think about headers right now, that's another headache another day. THe motor mounts need to be of the engine's brand so they'll bolt up to the engine. You may need to run a fuel line to the other side, might need to move the tranny's cross member, ect.
On the tranny part though, i prefer installing the tranny in the propper location. Put the crossmember in the TH400 location, install the tranny supported with a bottle jack and block of wood, and then dangle the engine in the frame rails. Mark where you need to mark, take a few digi-pics (if able) so you can remember exactly wht part of the fire wall you may want top dimple, and then get the engine back out of there.
Having the eniter front clip off is pretty much a must. You can do it with the fenders and all on, but it'll make you hate the swap.
