On your combo it might pick up some.
I don't know how your heads work so it's a crap shoot.
This car with a 394", 3.79 crank, has a pair of Brians ede heads on it with a SV intake and solid cam 260/.586. Runs low 10.60's at 125, low 1.40 60's on 275/60 MT ET street radials.
The car craft engine was not the best piece to utilize the SV. Even though it flowed better on the bench when attached to the head compared to the RPM, it was too large.
