Ok, base 1967 327/210 HP currently with the top end off. Bought the Edelbrock top end kit 2099 kit with the etec heads, supposed to be one of their top of the line top end kits. The heads are modeled after the Vortec heads with a Vortec intake. Supposed to produce 435 HP out of a 350 with 12' of vacuum at 1,000 rpm.
The heads, intake and carb, along with ceramic coated headers are going on, that's a given. Only question is do I put the cam on now, or save it for another engine?
Just completing phase 1 of my 67 Camaro. Paint, new wheels, tires and some engine mods to cure the 210 hp disease. The engine felt like it was running on 7 cylinders. I *believe* it was the heads, but cannot rule out a worn cam lobe, although I think it is unlikely. Compression test was pretty good, did NOT do a leak down test.
The cam that comes with the top end kit is fairly stout, there is my concern. I believe without the cam, the kit will put out over 300 hp with my 50 year old 327 stock short block. Seeing that the engine put out 275 hp with just a 4bbl carb and double hump heads, I think that is very reasonable. My math says it should put out over 400 hp with the cam.

My main concerns - 50 year old power glide (crappy first gear ratio), short block, stock 10 bolt rear end with 2.73 gears. Not a good setup (especially the stock torque converter and 2.73 gears) for a decent cam.
Engine will have 10:1 compression with a steel shim head gasket.
During phase 2 of my upgrades (probably over the winter) I will *likely* but a 383 stroker short block, O.D. (like a 700R4 or similar) trans with a better torque converter, better p-trac rear end with better gears (like 3.73 or so).
1. Install heads, intake, carb and headers, enjoy the upgrades as-is until I do phase 2.
2. Install above, plus the included cam.
3. Install option 1, with a cheaper, milder cam (not a great option due to the amount of work.) Save the Thumper cam for the final engine.
I'm leaning towards not doing any cam work at this time, but I keep going back and forth. I do have everything to do the cam, but it's a lot more work. I'm a bit concerned that the cam won't work so hot with a stock torque converter, a power glide (crappy first gear ratio) and a 2.73 gear ratio.
