    Engine An Engineering Question On Improved Torque

    So I know that everyone loves to watch your engine twist when you hit that gas. It just speaks raw power. But when I look at that I see potentially wasted torque.

    Can Someone Tell Me Which Engine This Is?

    Hey guys, I'm new here and am going to look at a 67 coupe tomorrow. They say that it has a 302 in it, but I'm trying to find out if its a 302 and not a 289 for sure. I know its not easy to tell unless you know what to look for. I know they didn't put the 302 in until a little ways into 68, but...

    Need To Know What I Need

    I have a 1966 Mustang coup. It has a 200 ci inline 6 cylinder engine. I want to put in a 289 engine in it. What other upgrades need to happen in order for this to happen? All I know is that I have to change the transmission and radiator, but that's about it.

    Rebuild C4 Or Replace With C6

    Hello Stangnet! I've noticed the C4 in my '67 vert is starting to take a while to engage when cold. I realize that this may mean a rebuild to replace all the worn junk inside. Not sure of the history of the tranny, but suspect it has never been rebuilt. Right now, I have the numbers-matching...

    Leaky Aftermarket Thermostat Housings

    I thought I would share a recent experience with the lowly thermostat housing. I wanted a new one and these are easy to acquire aftermarket for most any 289/302/351W from the 60s to the 90s. After installing with the paper gasket and some Form-a-Gasket No. 2, it promptly blew out the gasket...
