Solid roller cam question

So I'm putting another race motor together and needed some help on cam selection....Cars weights 3200 with me in it powerglide 1.80 gearset. 5.00 rear gear. Will have the bloomer heads with a victor 340 intake running on E85. I plan on going with 1.6 rockers. I thinking something in the .440 lobe 270 274 @50 on a 108 LSA.
