what converter are you running?
do you know what your timing events are at .050. you can pm them to me if you like.
mine is 54mm Bullet cam
286/298 @ .050
.475 / .470 lift (.855/.799)
114 cl

 

Here's the cam Steve from LSM ground for my deal.
I have a 540" 360Dart heads 14-71HHR 35-40 PSI boost. Clutch

Intake Lobe lift .510 1.8 rockers @ the valve .918
Exhaust Lobe Lift .500 1.8 rocker @ the valve ..900

Intake @ .050 286 Intake open 27 BTDC closes 79 ABDC
Exhaust @ .050 300 Exhaust Opens 86 BBDC Closes 34 ATDC

LCA-116 deg
Overlap 61 Deg

This is a LS firing order also (double swap)

 

Have you ran or dynoed this combo? Should make big power for a BBC

 

We are running a FTI 101 series 10" converter that stalls 6200 or so depending on the weather.

The valve timing @ .050" with the intake installed @ 114* centerline is:
Intake: opens 28* BTDC closes 76* ABDC
Exhaust: opens82* BBDC closes 34* ATDC
It has 62* overlap

It seems as though as you go higher in boost, you want a slightly wider lobe separation, but the tendency is towards slightly larger cams and higher ratio rocker arms as well. We are running 1.7's on our combination.

 

The engine at the moment(and me also) are anxiously awaiting assembly because I have to do some body work and a few other things but ya I'm really looking forward to screwing it all together to see what it will make for power.
