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!
