Another ss/gt ?

danny waters sr · 07-19-2011, 10:45 AM

88 camaro with 69 350/255/290 combo.
we checked converter flash and only goes to 5900.( checked with launch chip out and in low gear ) 198 p/g and 557 gear and 14x32 tires, wt 3265
what should it go to, i'm thinking around 64-6500 ?
car seems to die( or drop rpm really fast) once it launches
and how much would this help in performance?
help please ............

Danny, I think you're on the right track, you probably need 6600 or more. Also, you might consider moving up to a 5.86 gear.

Of course, that depends on how good your engine is. It has to be good enough to turn the necessary RPM, and make power when it does.

Consider that 5.57 with a 2.52 low and a 6600 converter is considered a decent base line for a stout big block SS car.

Get your converter out, get the serial number, and call the manufacturer to see what it is supposed to be doing in your car, if it is supposed to be in there. That will give you a good starting point.

Danny....your son needs a bigger foot.......LOL. Seriously....listen to Alan. I listened to your car at MIR and it seemed to labor in low gear. I tried to find you later but got side tracked then you guys were gone. I ran 5.86 gears with 14X32's in a SS/IA Camaro with a 350/300 back in 1977-78 at 3220 lbs. . Todays engines are a lot stronger and they use better rods, wilder cams, stronger valve springs, ported heads, etc. that we couldnt get away with back in the day. "Sling" that puppy !

I don't think that flash is out of line. Bout everybody that we know that has those combos, or similar ones, has their flash RPM in the 5850( Good Air) to maybe as much as 6150 in not so good air.That's just in my gang, and this is a big old country, so we might be the ones in left field......

We have another converter and will change it by the weekend and test it . I will let you all know the outcome,hope it will be good news,....And it is a good motor with good peices

Are you sure you're not having a fuel delivery problem? A car that worked fine before can start doing stuff like this when more power is introduced.
