Welcome to the board from South Mississippi! Post some pics of your truck. I'm no engine expert, but my uncle had a 350 that never showed much oil pressure and he ran it forever. I would put another gauge on it and check it to be sure your gage is reading right. The plugs burning up is probably related to the carb adjustment.

thats wat i figured but i have no exsperiance with carbs and so i have no idea on how to adjust it

Does the 700R4 have a lock up torque converter? How did you set up the TV cable? The set-up on the TV cable is crucial to a 700's life. Is your shifter going into 4th? or is the trans just not shifting?

not any help but welcome to the site and post some pics...... oh and nice screen name

Sounds like a cool truck. Love to see some pics.

Do you know what pressure your fuel pump is set at? What spark plugs are you running? How low does your oil pressure go once warmed, and how high when cold?

Oh, welcome to a great site and get some pics posted when you can!

fuel pump is a holly blue and its at 7-8psi the plugs are acdelco 45's i think is wat i saw on um and oil starts at almost 50 then drops down to below 25

[Yukon Jack]

Does it stay at 25 while driving or just at idle? They (who ever they are) say the rule of thumb is 10 PSI for each 1,000 rpm is all that is needed.

for the oil pressure problem, does it have a FRAM oil filter? i have heard more people complain about low oil pressure while using them than anything. if so, go to NAPA and get their store brand filter to replace.

also, it's possible the oil pickup in the pan is clogged. When you swap the filter, you might pop off the oil pan and see if the oil pickup is clear.

hey anybody else got any ideas on the motor and tranny problems

[oldgold70c10]

How old is that 700R4? I've heard of many exotic break-in techniques here and other places to get it to shift to 4th. Also dittos on the TV cable, it is very crucial. You should do a search on a net and find the proper TV cable adaptor for your aftermarket carb to get the proper pull and angle on the cable. This diagram shows the correct relation between the cable and throttle.


You may also want to look at the info on these pages http://www.purplesagetradingpost.com...o/700R4p1.html they show how to fab a TV cable bracket, but the ones I've seen online are cheap enough and look better that's it worth it to buy one instead of make one.
