Thread: torque converter?

Tweet

I'm installing a extreme energy hydraulic flat topped cam 218/224 dur. in my 305 bored to 315. I'm also installing World products SR torquer 305 head which have 58cc combustion chambers with 1.94"/1.50" valves for better midrange torque. I'm running a 3 duece set up with rochester carbs. I have high gears 2:76 with a stock convertor. If I keep these gears will I need to go to a higher converter? I know if I change to 3:55 gears it would improve the performance of the engine, but when I cruise its usually around 70-75 with the rpm's at only 2500 so my mileage is good.

If I do go with lower gears, what torque converter should I use?

what trans. are you using?

Chevy 350

chev. im not sure about this ?, but the only reason you would need to change the convertor would be to install a stall converter. that would be to controll your rpms and idle quality at the stop light or when you put it in gear. im talking for st. use. i dont use any more stall than i have to. i dont know about that cam but im sure the factory has a recommendation for the convertor you would need if any . you wouldnt need to change the convertor if you change your dif. gears. hope this is what your asking

Richard and It1s10 Thanks for the advice. I called comp cams and asked if I would need a converter for this cam and I was told no. I mentioned what you said Richard about the cam being a little more agressive in a 305 than a 350 but he felt that the engine wouldn't stall in the 1800 to 2400 range. I seem to have more confidence in your answer richard and if indeed it does stall I will put it on since it's not a major undertaking.

Don't know why I keep sticking with the 305 but it's been good to me and with the new heads and cam I should pick up substantial HP and torque.

if youer happy (with the 305) it dont make much dif. what the rest of us think. sound like it should be a nice ride.
