Installing 454 In 91 S10

I currently have a 350 in my truck now using the v6 mounting spots. It's bolted to a th400 tranny. I tired of my 350 and want something bigger so I found a deal for a 454. After reading other reviews and other forums and pics about installing a big block into an s10 I want to ask you guys about the basic installation.

Here's my plan...
New Solid Motor mounts
Hooker Hugger Headers with a local shop that will be welding some pre bent 3" pipe to go under the cab and out the side.

A/C housing will be cut
Driverside header will be chopped and re-welded to clear steering shaft.

I seen from other successful setups that the big block mounts in the same spot as the 350 being if I get to mounts to adjust my in/out setup.

I've pre-ordered the following:

LUN-00021LK Lunati Bracket Master II Cam and Lifter Kits
Cam and Lifters, Hydraulic Flat Tappet, Advertised Duration 304/ 324, Lift .500/ .510, Chevy, Big Block, Kit


Weiand Stealth Intake Manifold - idle - 6500
Edelbrock 750 Carburetor - Might exchage for a Proform or QUickfuel carb
Fel-Pro Cork Gaskets
A friend is giving me his old Valley girdle for my big block.
4.56 Gears | Thinking About some 4.11's though

Anything else you guys think I would need to do to get this bad boy on the road? Don't worry about my rear end. I already have a GM 12 rear sitting with a Strange Third member. I do have 4 links sitting somewhere I my garage or in the attic or maybe the city's got it. I just need the initail help on the motor

Thanks guys

Take pictures when you do the headers please! You will def. have to notch the crossmember.

Another corossmember was used so no worries. Plus i'm taking my exhaust out just right behind the cab anyways. All I need help with is motor mounts. Will they bolt where I have mine now or will I have to use this extention thing like the guy did on his.

If anyone has any custom motor mounts for Big Block motor swaps for s10's please let me know.
