Converter Problem/Question

Kingpen · 08-04-2009, 11:30 AM

as in my other thread,Im trying to figure out IF I have a torque converter problem.I have changed just about everything on the car chasing a problem.My car has steadily lost E.T. over the last 3 years for what I think is no reason,maybe Im wrong,maybe there is a reason & I have not realized it yet.I have put a new fuel system from Pump to Reg including new line,have tried both #8 & #10 line to front,#6 & #8 to carb-no difference either way,numerous carbs including Holleys,which by the way was only about 2 hun at the most diff.have been through motor 3 times with new pistons,diff ring set ups,even as far as putting in a 43# crank(350 chevy 295/327hp) and have not seen any improvement,took 43# out & put back stock GM too.nothing seems to change how fast it will run.Even from corrected air of 1100' to 4000'(normal for here in summer) never any more than .04 in E.T.the air change alone should be worth 10-15 hundreths.
So,i decided to make a drastic change,I put my bracket short block under th SS heads.377 ci with final comp ratio at about 12.3-1,yes the pistons weighs about 80 grams more and the rods about 50grams more-and I put some titanium valves in the heads to help with the aggressive SS cam.....final result---you could put the e.t. slips beside each other and thought it was same car on same day.......notta!
I guess my question is -will a converter "go bad" with out being "broken" and oh by the way-still be very consistent!I made 5 runs with .02 all night.the car has lost about .18-.22 in the 1/8 mile that i cant seem to get back.in fact ive always thought the car should have been about .08 quicker any way so really chasing 3 tenths..I have a converter being sent that Ill try to see ,but i have a hard time beleiving it because its never been broken and is still consisten..my converter is 9 years old but have been sending it in evry 2-3 years for freshen and they always say"looks good" when they cut it apart...............ANY IDEAS...I have been throgh all on the car except for a "new" converter......Vic Penrod
