Unless of course you are replacing with a recessed firewall. That adds other issues.

I belive with the March system you need about 7 inches clearance from the front of the block to the radiator. March makes some nice stuff, but $$$$$$$

The reason I ask is because I used a 700R4 in my 57' with a 3.55 and now wish I had a 4:10 or had left the TH350 in it. | | | | | Joined: Oct 2011 Posts: 20 New Guy | | New Guy Joined: Oct 2011 Posts: 20 | Dave' it has a 7.625 ring gear with a 3.73 gear and is limited slip posi | | | | | Joined: Dec 2003 Posts: 2,733 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 2,733 | I've had low speed vibration issues with the tranny in OD but it goes away at higher RPM. Since I don't want or need to drive 85 MPH I'd rather have the 350 back in it. After super tuning the engine some of the vibration has gone away but I'm still not happy. No vibration at all in direct drive. Hope yours works better with the 3:73. I've heard from a few guys that this is a common complaint with 700's but I fail to see why the General would build something like that.
Happy Thanksgiving. | | |
