Just do soem research, Its not a hard swap. Im going to get mine done (lord willing) in a week
 
The Schumacher headers are nice. If you change to the larger ball joint uca, my dad and I couldn't get the cotter pin through with the doctor diff adapter sleeve.
 
I had to clearance(notch) my kframe to oil pump and make sure you get the right oil pan with the notch, i didn't have to since mines a 74.

If you have manual steering and no column shift, Hedman 78030 B-body headers will fit with very few dings and they're only $200. BBD has a good write up with pics.

The low-deck big block is a pretty easy swap, especially compared to the first time I did it (early 80's) when there was no Internet to swap info and few performance parts except Direct Connection!
 
Headers are no fun, especially the ones my bro had and it was only a B block! We couldnt figure out how these headers were made for this 69 Fastback, dings and dents everywhere. B/RB's are fun but hot LA's are quicker. I could never overcome traction issues....CNC headed 451 in a 65..you think? :)

Tell us more about what your intentions are for the car. Street? Strip? Both? IMO the Schumacher mounts and headers make the swap pretty easy but may not be right for your objectives. I have a 400/451 with power steering and power brakes. I used the Schumacher pieces and they work well for me. Make sure you have adequate radiator/fan capacity. Plan out your transmission linkage/kickkdown. I used Lokar.
Driveshaft may need to be shortened and modified with the correct u-Joints. Heater fan motor may need to be relocated. Bigblockdart.com has a lot of good reference material. Good luck and post questions when you hit a snag.

Matter of opinion, I have never seen an LA run in the low 9`s at 3000 pounds , naturally aspirated. He even Backed the carb off and went 9.60`sw . There is a big block 71 cuda running 10 o`s backed way off here too.

we ARE talking street...right? No one is going to build a LA for 9 second drags. Unless your Carlton and want a 8.6 Colt or a Sox 8.98 Duster. Hoe about an 8.3 Arrow? Ok lets keep it real...street cars

so looking at shumachers mounts i wont have to source out a v8 k-member, correct?

The only wrinkle is, the Schumacher mounts are hard to get right now. You'll notice that many of the part numbers are "out of stock" on their web site. Their dealers, like Mancini Racing, don't have them in stock either, and there is no firm ETA on when they will be back in stock. I talked to Mike Schumacher a couple weeks back and he said he had a batch of A-body RB swap mounts nearing completion, but he was reluctant to guarantee that I could get a set; apparently, there is a waiting list of back orders. So if you want to do a swap in the near future, you might want to look at alternative options like finding a used set (which is what I did) or going with an engine mount plate or elephant ears, which a lot of people who have done the swap highly recommend.

However - Schumacher does have the Tri-Y headers for the A-body RB swap in stock right now...I just got a set delivered last week.

Big block K-members were only made in 67 - 68, are pricey when you can find them used, and from what I have read, don't work with all RB / B block castings. Direct Connection produced a big block K-member for a few years, but they are pretty scarce now and reportedly were not of the greatest quality when new. Another option is to modify a 73+ small block K-member. Sorry - don't mean to rain the gloom and doom on you, but I just went through this myself trying to figure out my path to a big block swap.

There's lot of good info on this page - definitely worth a read: Tips, Tricks And Tight Spots
