Engine issue help!
 

Just wondering if anyone might have an idea on why my sbc acts like it wants to fall down when I try to stall it up now. The engine is a 355 ci with 58cc chambers, throat cut, bowl ported with 2.02/1.60 valves. 13.54:1 comp. weiand single plane intake, 700 dbl pumper carb.
Cam is .488/.510 in/ex. • 300°/310° Adv. Dur. • 112° Lobe Center • 81° Overlap.
3000 stall conv. With th400 tranny.

Used to have a crane fireball 2 292 duration .480 in/ex cam in it and it ran like a champ with a 750 com carb on it, besides just running a tad rich.

Car falls down
 

MY opinion is convertor is too tight ,don't know anything about your car but I would GUESS at least a 4500 convertor. I also don't like the 112 C/L , I would want 106-104 Later J.Smith 4621 racing

car falls down
 

i agree the converter is to tight depending on what the car is used for u need about 4500 stall or more

going to say stall also. and im wondering about that 400 tranny. anything done to it...

He has probably figured it out by now. It's been 5 months since he posted this.

It's odd that the date of p68ramair's post is the 2nd but it came before outlaw256's post dated the 1st.
