What's up fam? I am thinking of going bbc. I have seen several bbc's on CL and most, that have been seen, have been truck blocks. I have been reading that the truck blocks are a little wider and taller. Will this pose an issue for swapping into our cars? Is one more preferred(truck or passenger) and why? Head choice also. Which is a better choice? I have read that the ovals are better. Also, reasonable price header choice. Any other info would be appreciated. Thanks.
