here's the deal, a few hundred miles ago i convered my cleveland 2V to an edelbrock 750 (stock heads) the engine is forged and was tuned and ran like a scolded dog! but right before i swaped to a 3.50 dif, she was having problems when the 4s opened, she would loose power tell i got off it and just ran with the 2s open. well now i got the diff in (had problems with wheel hop so i put traction bars on it too) well after she warmed up, i stopped having problems with the 4s open, but now she has a very studdered idle. sounds like it's skipping a cylender or 2. but when i get on it all the way, she seems to run fine again (can still tell a small studder)

does this seem logical to anyone? monday im gunna drop her off to have my hooker headers thrown on and i asked him to tune it since he's an old mustang guy. trust him more than an 18 year old working at some tune auto shop where they only work with newer ECU cars.

any help will be alot of help!

 

Sounds strange that it would bog at WOT, then change rear gears and the bog goes away at WOT but idles bad now. Just get the old Mustang guy to adjust that carb and you should be good to go.
