Like Don said massage the firewall right at the corner of the recess for valve cover clearance and its a drop in. I a nice set of 1-7/8" headers would look real cool in there as well.The right side of the firewall will need massaging for valve cover clearance and it drops right in on v8 mounts and frame mounts.Exhaust will be more of a challenge depending on your power level requirements.There are no swap headers for this package so if your looking for more than 500 hp they're a must and they would be custom.
Some applications like older trucks have strange front cross members. I would think the oil pan would have plenty of room, not sure.I like what Dan and Don call a "massage". To me, it's a beatdown! Some of the aftermarket mount stands will move the lump forward a little.
On the exhaust? 348 and early 409 manifolds will work. After that it gets pretty tight, especially when the truck is lowered and the front wheels/tires aren't "skinnies".
