Just purchase a lq4, 5.3 heads ported and polished. ls1 intake ls7 lifters. what is a better cam for this setup vengenace vrx3/vrx4 and what hp numbers i'm look at

 

My friend is also doing an LQ4 build but he is sticking with stock 317 heads for now and we are currently trying to find a suitable cam for what he wants so we are in similar places. The only advice I have for you is to ditch the LS1 intake and go with an LS6 intake.

 

thanks
