Thread: 71 performance 302 parts in 93 5.0???

Tweet

Your '93 uses a 5/16 rocker bolt that is non- adjustable. Your roller rockers probably are made for 3/8 rocker stud and nut. Without drilling your 5.0s, you will not be able to swap rockers. Which rockers are ticking? The '71s or the '93s? Other than the valve train, all 302s, 5.0s etc are essentially the same. They made some changes through the years, but all will interchange with little or no modification. Right now, I'm getting ready to fire my new 302. It's a '91 block, '65 289 heads, '68 crank, etc, so as you can see, they are all pretty compatible. Gimme some more details, and I may be able to help more. Small block fords are the on thing I know alot about.
