carbed and boosted 6.0.... I'm about to start gathering the parts for my second motor. I've got an extra 6.0 stock short block and plan on staying with the stock crank. I WILL be getting rods and pistons and this is where it all gets fuzzy. I keep hearing about boosted motors lifting the heads undor heavy pressure. Where's the line seem to be drawn as far as boost levels on stock design 4 bolt heads? I don't mind buying a set of 317 heads or even aftermarket to get the chamber size and shape I want but on say a 9.0 to 1 motor what kind of squeeze would it take. I'll stud the block etc also and use cometic gaskets where needed. I'm just looking for a starting point for a blow through carbed 6.0. Would LOVE to see around 800hp which seems to be very do-able on this combo. Any good info? Oh, and the reason I plan to carb it is because thats what I have now. The car is plumbed with #10 line from the tank and it's easy to swap my pump for a larger/higher capacity pump(the old blue pump will have to go I'm sure) Toss it out there for me to absorb folks!! Thanks

i have run 14 lbs boost on my 6.0-i am running a carb, Vic Jr intake, and
D1SC Procharger-i am using the 317 heads now, with the GM gaskets
been together about 1 1/2 years-i have made a few passes, a lot of street miles, so far so good-i reused the fact. crank, some cheap ebay forged rods,
and wiseco pistons-my hp range isnt up to what you want, im a little over 500 at the rear wheels-i didnt dyno it at 14 lbs, so prob was a little more, i think it was at 9 lbs when i dynoed it
the proper tune is big, timing, fuel, plugs, etc

with the old 6.0 i ran a 10.6 @ 126, prob could have pushed it quicker, but its all steel around 3700, not a cut up car, only had a 1.8 60'-i prefer to give up some speed for great streetability-you know, stereo, heat, p/s, p/b's, etc
hoping to go 9's with the new 403, getting the carb close, now all the tracks are closed, lol-i considered switching to FI, but i could build another engine for what it would cost, lol
the old 6.0 looked so good, gonna save it to replace my 4.8 in my truck
if i were gonna redue it again, def a turbo, would love to do one, or twins

so to make any kind of power you have to go forged rods and pistons. that sounds like the setup i want to run time and power wise but i hope to have my car way a bit less then 3700lbs.
did you use the msd to control spark?

i use the msd 6010 box, took a little work to fig it out, im kind of computer chalng., lol-i use the map sensor to control the timing, but prob could use the reg rpm graph to do the same thing-i had problems understanding the atmosphere thing, but got it down now, lol
i heard of guys having trouble firing them with slow cranking, prob below 150 rpm, but with the old and new engine i have had no problems
adding the 4l80e trans took the whole driveability thing to a new level, wish i had done one on my old chevelle(489/f1r procharger, would have been sweet)
