I found this:

http://www.projectpontiac.com/ppsite...=112&advance=0

ci 360.42, static CR 9.85:1 and Dynamic Compression Ratio 8.1:1

bore=4.06, stroke=3.48, combustion chamber=62, deck hight=0.003, gasket=0.041, piston dish=12, piston ring height=0.3, piston to bore clearance=0.0028, Rod lengt=5.7, cam intake duration=258 (seat to seat), lsa=112 (lobe centerline), advance=0

and this:

static CR 9.9:1 and DCR 8.82

bore=4.06, stroke=3.48, combustion chamber=62, deck hight=0.003, gasket=0.041, gasket bore=4.166, piston dish=12, Rod lengt=5.7, Intake Closing Point (degrees)ABDC @ 0.050 lift plus 15 degrees=31+15=46

The cam specs: http://www.compcams.com/Cam_Specs/Ca...?csid=193&sb=2
Additional cam specs information: timing events at .050" for the 08-500-8
THESE SPECS ARE FOR CAM INSTALLED AT 108 INT C/L
INT OPENS 5- BTDC INT CLOSES 31 ABDC
EXH OPENS 42 BBDC EXH CLOSES 10- ATDC

Wich one is correct?

Thanks.

 

I did it the old fashioned way, by hand, and my results match the second set you posted.

 

Appreciate your help, atilla.

What would a good DCR be, with .045 quench 9.8 CR and aluminium heads http://www.summitracing.com/parts/SUM-162108/ for DD street strip ?

I just downloaded the DCR calculator here http://members.uia.net/pkelley2/DynamicCR.html and it shows 8.27 ?

One thing I just noticed is all "Great fit" cams suggestet by camquest6, give between 8.66 and 8.88 DCR with this http://www.kb-silvolite.com/calc.php?action=comp calculator.

 

DCR is a great tool, but I was choosing cams long before DCR became common. Mostly I match the intake closing to the static compression, intake ports, and axle ratio. I have my own set of rules that work, I've never written them down.
I suggest you choose a cam like the GMPP ZZ4. Maybe not the ultimate at anything, but above average at everything (up to 5500 rpm) and a good match for both your SCR and your intake ports.
Assuming a 700R-4, I suggest a 3.42:1,with a B&M TorkMaster 2000, or with a T5 from an LO3, a 3.73:1. Both assuming a 26" rear tire, give or take 0.50", new and unmounted.

 

Well I already have the comp cam 8-500-8 but from what I remember it was similar to the gmpp zz4 cam.
The only options I have with 1.94/1.50 valves are TFS 175, 083 or 193 heads. https://www.thirdgen.org/forums/post...86-post30.html

Yes it has the th700r4, I will keep the 3.23, was thinking something around 2000 stall TC, I will check out the B&M TorkMaster 2000.

 

the Comp 500 cam will be okay if you at least polish the exhaust ports of the Summit heads. The ZZ4 cam doesn't HAVE to be used with any specific valve sizes. 3.23s are fine for the comp 500 cam, and the 2000 stall will feel great with this combo.
This is definitely a daily driver build that'll get mpg in the mid 20s if you take it easy on the interstate, it'll kill Hondas across intersections, sound stock, be easy to tune, pass emissions, and make about 360 horses around 5100 rpm. It'll want premium unleaded on hot days, but that's a small price to pay.

 

Wow sounds good
