Putting together a 520CI RB based engine. Will be running the trickflow 270 heads with port matched indy 440-2 intake. 1050 dominator on HVH 4 hole spacer. The car should weight 3200-3250 race ready. Will be running a 727 with 4000-4500stall converter and 3.60-3.70 rear gear in hopes to get down the road. Static compression will be between 11-11.5:1 depending on the head gaskets run in hopes to run 93 pump on the road. Engine will be sprayed 150-200hp couple times a year. I have a comp 23-770-9 .690 on the self i would like to run as i already have it. I have also seen an off the self crane 688651 on a wider 112LSA. Looking for a roller that is not to aggressive on the valvetrain. Or should i get something custom ground? Very happy with a porter racing cam in another 499" but hoping to use what i have if a lot of power/reliability is not left on the table.
