I would probably do the 112 version of the 704 before the 703 in a 455, especially if the compression is past the mid 9s. Power wise I think it would be down a little from the 110 lsa 704 version with the headers, but on the 112 it would be a friendlier pump gas driver combo for sure.

704 at 110 would not bother me with a/c. Just because it would not bother me though, does not mean it is ok for someone else. I have bigger cams than that with A\C. But, I like the choppy idle though. The 280/288 Bullet with the 112 lsa is in a friends 455 gto, auto with 2500 stall and 3.07s with A\C. My W72 T/A is a 245/253 HR with a 114 lsa with A\C. My biggest cam with A/C is a 255/263 112 lsa SFT, 542 cid though. Not like they are 4 bangers engines that pull down when the a/c kicks on.
