Final Eng. Set Up
Well after alot of research,I've come up with the final componants for my eng. First I have a 350 4 bolt main .060 over w/9.7:1 cr. I'm going to now install cast alum. flat top pistons(w/ small valve relief,like a stock top),a Edelbrock alum. manifold,a Edelbrock 750cfm carb.,Speed Pro cam(.443/.465 214/224),headers. and the plus side to this is that,when I pulled the heads(cast camels) I found that I have 2.02" valves as opposed to the 1.94" valves that I thought I had. I was wondering how much benefit I can expect from the larger valves W/ported(unpolished)heads? Really the reason for posting this is get some input as to my decisions due to the fact that the help I received on this forum helped alot,especially with the cam.(Thanks Cardo and Jackson). Also I don't know if this is poss but,can anyone give me a rough estimate on my anticipated H.P.? Thanks again guys,the forum comes through for me again. 
Later,

That would be cool if this can be done. I would want to know H.P.
#'s for my setup also.

How 'bout if you guys guess and I'll see if I can get it on a dyno when and if I have any money left over from this project. Then I'll post the results for bragging rights and maybe I can come up with some small Prize.

Getting it on the dyno is probably one of the more important things to do.
Right outta' the box, the parts will work together, but you'll most likely be leavin' a pile of HP and Tq on the table.
My tuners got me about 50 HP 1 jet size at a time and 1 degree timing at a time. That was about a 12% gain.

Thanks Tony.
Yeah I'm going to have to find a dyno to get it tuned to it's max potential. Whats preferred,a engine dyno or chassis dyno??? Never had any exp. with a dyno. As a kid I just slapped some parts together and drove like my hair was on fire.

Think I might go with a thinner gasket then.

You can use either a chassis or engine dyno.
You will find that a good engine dyno will have better instrumentation such as individual cylinder exhaust temperature pyrometers, airflow and fuel flow sensors. This will give the tuner better information to work with. Allowing them to tune both the primary and secondary sides of the carb
If you want to get everything the motor has to offer that's the route to go.
Most chassis dynos can only use an exhaust gas analyzer, rarely any kind of pyrometers or air flow measurement, so while they will get you into the air to fuel ballpark, it's only in the ballpark.
Again, "My Opinion"

So what i'm saying sly is don't worry so much. If u matched ur cam right to the c.r., heads and c.i. u are way ahead of most - it should make good pwr and yet fun to drive with little problems.
Heck look at the Goodwrench 350" crate eng. For $1300 u get a low c.r. 260hp 350". But GM now sells the same eng for $1600 at 290hp with only a cam change, no other changes, but charges us $300 more though dosn't cost GM an extra dime.
U can read Chevy Hi-Performance articles on a Goodwrench 350" build-up to over 400hp and get an idea where ur eng fits in for hp. I read it many times and still enjoy reviewing it.
But what is critical now sly is to break that cam in correctly and right away - no low rpm. If the eng won't start in less than 5 turns then stop and find out why. Believe me, changing cams again after all that work is not fun or motivating.
Good work and have some fun with that car now.
