Hey there.

since I worked my /6, (rebuild, cam, head, headers, dist recurve, other goodies) I feel as if the stall speed has increased a li'l bit, like 1300 rpm. Also this ain't much noticeable at light throttle, but when I really step on it. I checked but ain't slipping (tranny's also been rebuilt) can the increase of HP on an engine somewhat affect converter's stall speed?

Thanx
Juan

Yes, exactly.

1300 rpm seems like a nice bump, how much HP did you add? :wink:

considering that my engine was dead before the rebuild (all comp rings shot, scratched bores, bad main timing, cam centerlined wrong, crappy dist curve) and what I did (rebore, flat top pistons .020 overbore, mains, new connecting rods, block top milled ~.015 head ~.035, steel gasket, li'l surface cleaning on ports, custom dual headers and dual ex, new mild streetable cam yet li'l more peppy than the older one...) I think that I might be over 180 hp SAE. I'm about removing the fan and use 2 electric units... that would add some too ;-)

What I notice is that if I go easy on the gas, the converter stalls very close to what it used to be, but when I come up like more than half throttle (or WOT, hehe) the beast revs up and then the conv stalls occurs, a li'l bit delayed, producing a very nice kick in the ass feeling and powerful acceleration. I happen to be "not-that-happy" with some middle ground (between light throttle and WOT) tho I wouldn't say that is crappy, maybe I'm a li'l bit short of gas in the middle circuit... idle is fine, power is fine... maybe I have to somewhat richen up the middle.... Or it could be my new recurve opening all too soon.... leaving me "leaned" when I want to regain speed after some transit event.
