    with it being a 4-1 its all top end power right ?? how does it compare to other 4-1 manifolds as i cant find anyone on here thats using one

    yer 4-1 is top end, 4-2-1 is midrange. the gmc is a very well engieered product

    for the price id go stainless. also you wouldnt tell a diff between a 4-1 and 4-2-1. raceland for the price really but if you want to pay more have a supersprint or a miltek

    +1

    on all the high performance tu5j4 engines ive seen, the 421 has always proved just as good top end with slightly better midrange but you would be hard pushed spotting it out on the road.
    racelands are a budget manifold but they are genuinly good for performance and ive seen a 190bhp tu enigne with raceland.

    Raceland copied Supersprint so the raceland makes good power. But the supersprint will perform better due to being better put together with gas purged pipes so the welds do not penetrate into the inside, collectors are optimised with angles, etc etc
