I must be a glutton for punishment but here goes...
The factory GM frames are extremely strong and should be suitable for your mods without fabricating a new front clip. As a know it all youngster many years ago I did this same mod. Pictures attached are of my S.O.B. (66 Chevelle SS396 raced from 1967 to 1978) when we pulled it from storage (38 yrs!) recently.
The straight front axle and ladder & panhard bars were installed to the factory frame with some reinforcement where needed. As I recall we used a early '60's axle from a F**d pu, fabricated some spring hangers, had the leaf springs made, and hooked it all up to the stock steering box. Surprisingly, it drove and handled fairly well both at the track and on the street.
I've wished 1000 times that I had just left it stock... particularly when I check what a "real", 66 SS396 is worth today! Good luck with your project should you decide to move forward with it.

Welcome to the site, we do like pictures. PS, I moved your thread to the non Olds engine section.
I agree that none of us had any foresight into what the future values of some cars we managed to inadvertently destroy, mod, mangle, sell, or any other reason we don't have them any more today but wish we did. No flaming required, your old gasser Chevelle is still cool. Did it remain a BB? 4spd?

^^^ Pretty awesome David. Going to try and make it to Burnet for 1st Friday later on.
Haven't had the vert out in a while. Still looking for a correct POA valve for it.
Are you coming with the 66? I know it has air...
To the OP, welcome to CO. We don't mind, post your build under uhh, what is it?
'Other than Olds' or something to that effect forum. Most of us are lovers of all old muscle anyway.

Eric, we ran a 439" BBC, semi open chambered cast heads, short plenum tunnel ram w/2 660's, BIG Crane solid lifter cam & stud girdle, Hooker Headers w/turbo mufflers for the street, Doug Nash 4 speed, Black "Pro" Hays PP w/ sintered 4 paddle bronze disc, original 12 bolt with a Moroso Brute Strength Posi and Zoom (IIRC) Pro Gears, Henry's Axle's, etc. Best Et in the mid 70's was 10.80 @ 135 @ 3800' altitude- we didn't know to check density altitude back then-(slicks & uncapped) all steel body-less hood-, factory glass & interior. The thing probably weighed more with the mods than it did stock! 
The best part was it was nearly as fast/quick capped up and on MT street tires... cam lift and duration killed enough bottom end for it to work!
Adam, I'll probably bring the Olds out unless I get too lazy! The sob is under the lift & the Olds is on top... where it should be! Hope to see you at the show in a few!
Thanks for the opportunity to bring back some great memories from another time.
