Looking to fix my bad combo...suggestions?
Looking to fix my bad combo...suggestions? The chassis/tire combo on my car is fine, I'm not having any issues there. However, my cam/converter/gear combo is sucking big time, and it's time to fix that. Right now I have a Hotcam, a loose 4000 stall (the STR is unknown) inside of a th350 (stock style gear ratios in it), and the stock 3.42 10 bolt gears. My thinking is that the converter is too big for this cam, and the gears are too low for the converter (since I have a "lazy" th350)
I've done quite a bit of research, and a lot of checking other people's results. The best solution I have is to go with a 3800/2.2 converter, 3.90 gears, and the TRak cam
I'm not worried about top end (i.e. 140+) on this car, nor am I worried about "drivability" (I have another car to daily drive...this one is driven on weekends mostly, sometimes once a week to work). However, I think that 4.10/4.11 gears would be too steep, as I would run out of gear a bit too quick
So what do you guys think of that combo? Anyone have something better? My shorter term goal is to hit 11s on the engine, then spray it to see 10s. Later on when I have more money I'll do more engine work to try and hit 10s N/A, but for now 11s is good enough

1) dont worry about STR. that is a joke
2) a 4000 stall (if it truely stalls at 4000) is NOT too big for that hotcam. a 200 rpm difference in converter wont make any difference at all.
3) gearing only matters what sized tire you are running. i run 3.73+28" radial and its as much gearing as i want. my car 60' well. 1.5 on the motor, 1.3 on the jug
4) your th350 has more gearing than my th400. nothign lazy about it at all.
what are your track results? why do you think its so bad?

Talk to the guys at Fuddle Racing. They have been really helpful with my stall selection. Otherwise from what you are saying the cam matches the stall, and TH350's are strong well geared transmissions. You need to upgrade your rearend. I'm no psychic but a 10bolt will not last too long getting hit with a 4000 stall. Go with a 9" and either 3.73 or 4.11 gears. If it is mostly a track car then I would say go with the 4.11.

I took the pan off today, and there was a pretty good amount of metal flakes on the drain plug. I'm thinking between a rebuild and a fresh converter, most of the problems should be taken care of. The trans was not rebuilt before I put it in the car, and I have no idea what kind of abuse it took before I put it in (was in a time bind back then, and I had to get it in asap...but I have all the time in the world now)
sounds like you have a ton of variables. dont go buying a converter or a rear untill you get that tranny figured out. i still think the only way to figure out if the converter is junk is taking it to the track. assuming you have enough tire and power the converter will tell its story. you cant tell over the net what is going on. figure out what rpm its turning through the traps.

My Camaro would do high 1.5s and low 1.6 60's no problem with the stock cam (stock motor) and a 4,000 stall on motor with 3.73s and no power adders. You don't need a tighter converter, just fix your trans and then take the car to the track and see what it really does. What tires/wheels are you using?
