Suspension for 429 engine swap

[brutus240]

I am wanting to put in a 429TJ engine in my 71 F100 but don't want to collapse the suspension. What suspension should i replace the stock suspension with to do this engine swap?

Since your truck originally had a 360 I would not worry about the 429 since it only weighs 100 pounds more

10-4 on that , Years ago I put a 429 in a SWB that originally had a 300 six in it. Did nothing to the front and it sat just about right for what I wanted. Was a really fun truck, A great "sleeper" With a very minor build on the 429 it ran mid to low 13's in 1/4.
