thats not bad for one of those for sure. I have a 7aFE head laying around from a 7AC build i did for an 83 ae71.
I think that advancing the intake cam a few degrees could really help get the 4age sweet spot into the freeway rpm range. i know they make most of their power at 5000+ when you really rev them up.
i think the 4age LSA is around 116. even reducing it to 112 could make the engine operate more efficiently and with a more natural egr effect.
