Thanks for the info man. I am worried about that exact issue really. The main thing is the cost and I keep justifying the flow numbers on the 210s being high as the reason I don't need to spend the extra 600-700 for the shaft rocker setup I will need with the 227s. Not even sure I can change the order yet anyway...thinking about checking with the speedshop tomorrow on this though. I know I am driving this guy at the speedshop nuts at this point.
The other thing is how fast I can run the quarter in a 3500 lb car with this motor AND my basically stock, but new drive train with the tremec TKO trany and the dragvette girdle. I was figuring I was at the limit at 600 hp, but would eventually break something (and then have a good excuse to look at a Tom's setup. I do have heavy offset trailing arms, cryogenically treated axles, new heavy half shafts and driveshaft as well.

I'm looking at a couple of options in custom grind setups. Hydraulic roller cams. These numbers are adjusted for the 1.6 rockers.
1. 248/256 dur @ .050, 640/640 lift, 112 deg LS
or
2. 234/240 dur 622/624 lift, 112 LS
What do you think?

I would go with the bigger duration cam, not sure about how much vacuum you will have though, bigger cubes will help.
I am slowly putting together parts for a 600HP 427ci small block myself. To get the HP I think I have to use a solid roller, I am however seriously considering a Comp Cams hydraulic roller either the 286HR or the 305HR, the 305HR is only 244 degs duration and you can get .640" lift with 1.6 rockers.

I would base it on what ever CR you are going to have and what gears you are running. Which ever cam best matches all the components would be the best. I wouldn't worry about lift as much as I would how many RPM's you really want to turn with it. The longer duration is the more compression your going to have to come up with. I used to work with a guy that put in a huge duration cam and a .600 lift cam around there anyway. I checked the cams specs for him, it was supposed to have a minimum of 10.5:1 CR operating range. He had it in his stock 8.5 CR camaro and wondered why it sounded and ran like sh$t. The mechanic that did that for him should have been ashamed of himself.

Probably shouldnt have started the other camshaft thread. I have the TKO500, think its a 3.27 first gear? This with a 3.08 differential and a 295 50 15" wheel, think it's around 4.10?
I drive it 1-2 times/week, but mainly want it for bracket racing, but all my car specs on the camshaft thread I just started, but I really wanted to push the drivetrain to it's limit and if it breaks, buy a Tom's...
