You guys can hit 55? Lucky... my truck ith a 218, 3 speed top loader and 4.78:1 rear end tops out at 50, gas pedal alsmost through the floor, engine trying to jump out of the frame. My dad used to drive it in high school, said the only time it hit 60 it ended up breaking the crank in half and holing the stock block.
I'm hoping the 230, 5 speed and more modern rear end (Ranger 4 banger) will let it do better than that. Might go ahead and upgrade the rear again before I bother swapping the Ranger axle in (afraid it won't hold up). I'd really like to run an IFS/IRS but I'm so far beyond broke it isn't remotely amusing... I can't even swing free parts right now (ran out of welding wire).
