Are you sure its not a 4.9 300 inline 6?
What are you doing the swap in? If it is a Dura spark carbed F100-F250 it is pretty straight forward. First you need to pull the 4.9. Then you need to unbolt the engine perches and bolt in a set of 302 engine perches. You will need a flywheel and starter for the 302 to match your transmission (manual or auto). You will also need a set of 302 engine mounts and the engine wiring harness for the 302. Everything is a bolt in and clip together swap. Use the search function, this topic has been asked a ton by me included when I did my 300 to 351w swap.

Hey, thanks a bunch. I'm working on an '83 f250. Does the 4.9 flywheel fit the 5.0? Sorry I didn't get right back to you, too many irons in the fire.
Do you have any info on removing the smog sys. I recently "fixed"/ it, and performance (esp fuel mileage)went to crap. Now it spits back through the carb, and bucks like mad when I try to accelerate. Can't figure it out. All new ignition. It's a puzzlement. Anyway, thanks again.

I'm getting too old for this...
Thanks for the heads up. I just put 4G in the suspension and misc goodies, and now I can't even drive it. Bummer. Oh well..

Thanks. Really want to keep the 6, but just can't figure out what's wrong with it...
