dyno not dino.
1965 352 block, H395P standard 360 pistons (four relief valves), 390 crank and 390 rods, Crane Cams 343942 272/284, Lift .533/.563, stock lifters, heads are C6AE-U ported polished with 2.09, 1.65 valves, edelbrock intake performer RPM, edelbrock 1405 600cfm carb, shim head gaskets 0.20, long tube headers running through glass packs

 

do you know what the compression is? or how far the pistons are below deck that i can figure it out? Also your heads are simmilar to the c6ae-r's? I have larger valve port data for that head that i can use if they are close to get you in the ballpark.

 

I'd say about 375 hp. That carb is going to put a cork on it. As will glasspacks.

 

thanks guys, seems one problem after another with the rebuild though, as we sit bench dyno is all I got, as we sit I have a 1000's of dollar boat anchor

 

Just trying to learn here. Why would the carb and glasspacks restrict on this set up?

 

I borrowed this data from the internet, no lab name was given.

Part 2

And according to a dyno post i saw but can't remeber what motor. The motor had a loss of 10HP and 11ft/lbs of torque between louvered and non.

So as you can see depending on what "glasspack" you are going to run or are running they can hurt flow a fair amount, even more if you are running smaller pipe than optimal for the engine.

As for the edel 600 carb. I don't see where you would have issue with a 600cfm flow carb until you got into the 5000+ rpm range. I beleive too many people over size a carb and sacrafice response to say "i got a 750 double pumper on my 302". Now as for it being an edelbrock, The one i have is VERY reliable and never gives me any problems, but the difference between that and my 650 mighty demon is very noticable by the seat of pants.

Look around on the net and you can find carb CFM calculators, just be honest with the RPM range you will be running it in when you pick it.

 

Edelbrocks tend to be undersized compared to a Holley of the same CFM rating. A 600 will limit the topend performance on a 390. A better pick would be a 750 cfm carb. And as shown in the post above, glass packs are notorious for restriction. Especially the smaller I.D. ones. The smaller the I.D and the longer they are, the more restriction you'll see.
