While messing around doing a burn out in my truck I noticed a miss and thought my rocker arm came loose. Checked and I broke one of my valve springs and connecting rod. I'm looking to upgrade all of my stuff since I'm pushing a bit more horsepower then stock. Just wanted to know if anybody has rebuilt these engines to push some power and what all they used. Links would be great to thanks

 

351 Windsor right? I've built one into a 408 and and done just about everything on 302s as well- Exact same motor - more or less - just smaller.

How much HP are you looking to make? Stock bottom end is fine for most things.

 

351ms are different than a windsor. If your upgrading personally if i was you, id look to find me a windsor to put in it.

 

No it's a 1979 modified and its already built. I'm just looking at upgrading the connecting rods pistons valve springs and push rods and I'd also take suggestions for other upgrades. I like using the modified though its pretty rare compared to a Cleveland or Windsor
