I have a 84 Camaro Z28 a weekend cruiser/bruiser, with a 383 stroker, 10.5, dart iron eagle heads, edlebrock rpm air gap, a 750HO mechanical DP carb, by AED, it has a comp cams XR288HR-10, http://www.compcams.com/Cam_Specs/Ca...?csid=161&sb=2, engine dyno was 486hp@5800, 478trq@5100, I have a stage 3 built 700r4, a 10bolt posi rear with 3.42 gears, and using nitto nt555r drag radials-275-50-15. I currently have a 2600 lockup stall, and a recent chassis dyno, it produced 350.69rwhp and 369.08trq.

At the Lakeland dragstrip 1/8th mile, I ran a 60ft.. 1.817
660ft.. 8.223@ 86.25, The carb tuner said I need a bigger stall, he suggested a 3200, what do you guys think?

I'm going be in the market for a convertor soon, and I'm thinking about a 9 or 10" billet cnvrtr, maybe a triple disk style if it'll be benificial...

 

If you are going for max straight line performance and you motor truely makes max torque at 5100rpm then I'd go with a lockup converter @ 4500rpm stall with kevlar clutch disks.

 

If you want to maximize strip performance than I agree with the above. I find converters that stall over 3,000 or so annoying for street use though. YMMV
