I just picked up the old top end parts of my cousins 69 327 there was about 5k on the engine when we built up th top end. Any way I bought the weiand Accelerator intake and stock heads (1.94/150 valves) and a Mallory unilite dist. The car actually ran pretty strong with the single plane intake. I'm planning on using these on my 355 that is going into my 63 gasser. I know the heads are not real good but they will have to do until I can get a set of better heads ( I know a guy that will port them for some beer) with a four hole spacer and crane 278 cam .467 lift and 222* duration. I'm going to get the heads surfaced and add flat top pistons (approx 9.5:1 comp) would this be a decent combo or will I be REALLY disappointed???
