Vegeta Posted October 23, 2003 Report Share Posted October 23, 2003 uh. .370" for the valve sizes eh. What a POS engine! Seriously, here are the CORRECT specs to use in DD2k. I used some incorrect specs to come up with the 13 degree exhaust retard...and it works like it should in real life according to that. With the correct specs it shows nothing much at all. Anyway.... Bore = 3.620 Stroke = 3.31 Intake Valve = 1.436" Exhaust Valve = 1.258" Compression 9.25 (9.5 for manuals, 9.7 for 96/97 engines) Inductions...just guesses, 600 CFM, tunnel ram manifold. Sequential fire gives closer to stock specs though but the tunnel ram is what we use for the pushrods to get them closer to spec stats. Exhaust, stock manifolds and mufflers Cam: Stock street/economy Lifter: Hyd Cam Specs @ 0.050 lift Int lift = .370 Exh lift = .370 IVO: -1.5 IVC: 42.5 EVO: 45.0 EVC: 3.0 http://60degreev6.com/download/DD2K/ I dont think the .flw file is accurate either, so I used the flowbench pic from DKOVs heads to make my own. The .dyn file there is the one I used that is incorrect. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 23, 2003 Report Share Posted October 23, 2003 For the CFM, I found this Equation a long time ago, telling how to figure CFM. Take the max rpm for the motor, multiply it by the cubic inch displacement, then take that number and divide by 3456. So for the DOHC: 7000*204.4= 1430800 1430800/3456= 414.0 Quote Link to comment Share on other sites More sharing options...
Vegeta Posted October 23, 2003 Report Share Posted October 23, 2003 Yes, but I think that number isn't what the engine needs, but rather what the intake can flow. That program doesn't even know runner length or volume. Its good to play around with but thats about it. Quote Link to comment Share on other sites More sharing options...

It does need a place for intake runner length, and volume that would make it A LOT more accurate. Quote Link to comment Share on other sites More sharing options...
