Love my car I just got a few weeks ago... A little car history
Sat up for 10 years
Since in my hands I have flushed the engine, fuel tanks added all new oils and trans gaskets updated cat converter...
Engine 350 v8 5.0 has under 65,000 miles so I want to keep it for now... But I do want to make some upgrades I was thinking of purchasing a new 700r4 trans because the one I have in it now seems to not shift properly and it looses power when I go up hill "point in begin a few times going up a steep parking lot structure It dragged *** big time" can I just make a swap out for a high performance trans or should I just purchase a after market 700r4

 

No help? Is there any test I can do on the trans to figure out what's wrong
When I start up the car my rpms are high above 10 and when I'm driving sometimes the rpms won't go past ten

 

I would check to see if the engine is either a 350 or 305 (350 = 5.7 and 305 = 5.0) it may also be worth while to check and see if your TV cable is properly adjusted.

 

It's says 350 5.0 exactly on the inside of the hood I'll check the tv cable thanks brother

 

Post a picture of where it says 350 5.0, sounds like somebody stuck a sticker on it.

The 305 is a 5.0 L engine and the 350 is a 5.7 L engine.

Check and adjust the TV cable on trans.

Get a timing light and check and adjust timing as needed.

Replace spark plugs, plug wires, dist. cap, rotor button.
Replace fuel filter, air filter, pcv valve.

A good tune up will help your up hill struggle a lot

 

I think you're right it's a 305 with a 700r4
