Re: Thinking about replacing th350 with 700r4
I have a 1970 Nomad Sta. Wgn. 307-2V engine with a 350-T tranny. If you have a GOOD 700R4. Here is what you DO NOT need to buy.
1-- My 350 tranny cooler lines bolted up to my 700
2-- Move the crossmember back, and bolt in the 700
3-- look on your old engine for the piece with the 5/8" square hole. This is the same size hole as the 700 TV cable,
4-- Get a small machine screw 8/32-10/32 whatever. Grind the O.D. to match, Then grind off the sloted part to match the width. Then drill a matching hole in your carb-- 1 and 1/8" from the centerline of the butterflys at 58 degrees to the rear. This is a static adjustment.
buy a dual pattern flex plate from summit 60-80 dollars(700s have a small pattern
5-- Take the " U " shaped shifter from your 350-T and bolt it on the 700 and re-connect your stock shifter
6-- My seven year old lock up kit still works fine, It cost $99.00 shipped to you house. Run a 12-Vt. Ign/on with an inline fuse and plug in to the 700 plug on the tranny, This is an Elect. loc-up. No magic involved.
7-- I did add an extra cooler or I am running two coolers
8-- Most of the parts you need except-Drive Shaft getting cut// Flex plate & loc-up
are in your garage. The stock 700 (Red ) dip stick bolts to the bellhousing just like the 350-T.
9-- Where did I get all this information???? I went to a junk yard and looked at a V-6 or a V-8 Chevy with a 700R4 and got out the yardstick and copy down some numbers. NOTE: For the rear mount for the TV cable, To make it look real stock, Find an old chevy P/U with a Q-jet and a 400-T. Look on the back of the Q-Jet. Take out the back two bolts and WA-la You now have a bracket for the TV cable and it is in the correct location.
My I.Q. is about 3 points above an orange traffic cone. My 700R4 has been working fine for 8 years now. I have a 3:07 12 bolt in my Red 70 SS 468 wagon . on the interstate at 72-75 MPH the 468 is turning 1950 RPMs and 19.7 MPG. Now I added a electronic servo cruise control, Just to give my foot a rest. My wagon is on its second set of tires, 3rd B.B. and the same 700R4. Good Luck and Git-er-done
