    Just got my rebuilt 355 in my '72 this evening. It was my first motor swap and I dropped it back in alone (my pop helped me pull it a few weeks back).

    Got the bell housing and Centerforce dual friction clutch from another member here on NastyZ28...everything fit perfectly.

    Specs on the new motor:

    -.30 over ZZ3 shortblock done by Mark Jones (before I bought it). Pretty much a stock bottom end.
    -Isky 272/282 hydro roller, 225/235 at .050 with .505/.530 lift and 112 LSA
    -Stock GM roller lifters with Trick Flow 1 piece pushrods
    -Comp Magnum roller rockers (1.52:1...might swap on a set of 1.6's next year)
    -Pro-Filer 195 heads...64cc combustion chambers, 2.02/1.6 valves, .015 head gaskets for .038 quench...makes for about 9.7:1 compression (lower than what I wanted, but that's life)
    -Weiand Stealth intake manifold, 650 Speed Demon carb (I hope the hood closes...might need a new drop base air cleaner...eek!)
    -1 5/8" full length headers...will be replaced next summer with the 1 3/4" variety...these are beat up pretty good.
    -MSD 8360 distributor and a Mallory coil.

    It had a Vortec 350 in it when I bought her but it was pretty tired. I hope this swap garners some mid-13's for me...I do live at 7200 feet of altitude but the track is around 5000 feet so we'll see.

    All is mated to an M-21 and an 8.5" rear with 3.73's, an Eaton posi, and Yukon axles.

    I hope she starts without any troubles. I did a retro-roller cam and head swap on the 383 in my '56 earlier this summer (same heads, similar cam, but a little more lift). That thing is awesome from 2500 RPM on up with the Pro-Filer 195's...so I hope this 355 doesn't disappoint.

    Here's my ride and the new motor...yep, it looks like every other small block!

    Kudos to doing it yourself. That sounds like a pretty nice combo, you should have fun with it.

    I just have the mounts all bolted down at this point (motor and tranny mounts that is). Dropping it in and getting it all mounted took me about 3 hours...I had a few hangups. Probably could have done it in 2 had I not run into a few issues.

    Still have to do the driveshaft and hook up all the electrical. Shooting for a start-up this weekend.

    Still need plugs, anti-freeze, valve covers, and manual transmission fluid.
