700r4 pains

[tlman]

ok guys help me! I think im using a 73 plus rear cross member it worked with the th350 ,now I am hitting the floor with top of 700 ,headers are pointing down,hmmm on an angle ,ive reworked the cross member and have it away from the floor ,but headers still point down slightly ,this truck has been apart totally ,only thing I can think of is that I have to shim cab up to raise the trans and lift headers up ,this is a complete resto ,original engine mounts but like I said ive reworked rear and still near floor and collectors on slight angle
Any ideas trans oil pan visually is lined up with frame rail ???????

The 700r4 is a bigger body trans than the TH350 was... If you have a short hump in the floor you may need to get a high hump... and then change carpet, ect, ect...

You have drive line angles to think about... if the motor and trans are at too much of an angle, youre gonna have issues...

I "had" a 700r4 in my truck with a BB and a low hump floor and didn't have any problems. I built my own transmission crossmember after I got the engine and transmission where I wanted it, but I did have enough room under the cab. The reason I wanted to see a pic of the headers is to see if they turned down somewhat, if that's the case they won't be parallel with the frame.

Now Thats something you dont see every day... Love the big truck hood latches

i have enough extra parts to build tilt hood again and put regular front clip on for now and take my time building new

Today you can find linear actuators that will open it for you, just an idea.....
