Subject: Re: Transmission question by dan0617 on 2008/12/31 20:16:20 You honestly think mid or possibly low 11's would be possible with my new engine combo, not revving past 6300 rpms? Wow, I'd die if I ran a mid or low 11 on motor, I was just hoping to get an 11.9 on motor. I really thought 10.5 and 128 mph would be a stretch on a 200 shot, thinking that not revving past 6300 would make it hard to make the hp to do that. But I'm not a drag racer, I'm a guy who scrounged up every penny he could just to buy a corvette and now can't believe that it ran a 11.43 and may make 10's! Might start looking into loosening up the converter then. I don't plan on spraying till after it shifts to 2nd gear to help the rear survive a little longer. Original plan was to swap converters when I get the solid rear in a couple of years, but I didn't realize it would make that much of a difference going up from a 2800 to a 3600. If you want to know my entire combo, it is a 383 made from a stock 400 crank and rods, machined to fit in a early 80's 350 2pc rear seal block. Stock 400 rods is why I'm limiting to 6300 rpms. Has Speed Pro forged pistons, Leghumper (LOL) 195 eliminator heads, 11.0:1 SCR, .035 quench, 8.9:1 dynamic CR, 230/236 flat tappet hydraulic cam on a 110 LSA (XE274H, I think), 1.6 rockers, Crane Hi-6CD ignition with timing retard box for nitrous use, smallcap MSD dist. and remote coil, HSR intake with custom plenum, hooker 2151's with true duals and LT1 catback, Innovate LC1 wideband, 275 Nitto 555R drag radials, 3.07 beer can rear, and you know the trans/converter. Zex nitrous wet nitrous kit with all the bells and whistles. I spray on the street all the time. My goal all along was to have a mild mannered street car that runs bad ass at the track or airport flashlight drags. I try to get all used/inexpensive parts that compliment each other to run good rather than huge expensive parts that kill my wallet and my street manners. I truly appreciate your opinions/suggestions here as I know you have much experience here. I just assumed that since the 2800 converter was keeping my rpms between about 5200 and 6300 that it wouldn't be worth much to go up in stall speed. In your opinion, what would my revs drop down to after shift with a 3600 stall? I know it is a guess but I'm sure your guess would be better than mine! |
