How much converter pressure are you running ?
i did the same thing with not enuf converter clearance to flexplateHow much converter pressure are you running ?
is the converter balloning by chance
We had a similar issue using a billet flex plate.Put a cheaper/thinner flex plate in and the problems went away.this question might not directly involve itself with chassis building but i figured i would try to put it out to as many ppl as possible. what i have is a normal 10.5 car...3100 LBS. BBC, turbo 400, fogger....car runs consistent 7.70-7.60's 1.14-1.18 60's drives straight ,doesnt wheelie to much.
the problem we are having is the engine keeps taking out the thrust bearing on the crank. we have checked driveshaft play (3/4 is the closest it gets both directions of rearend travel). the engine is mounted double rail with a 3/8 thick mid plate and a halo behind the plate about 1 " from the bellhousing.
the crank is bryant so ill stake that they arent using junk metal. all of our engine builders are top notch and do quality work over the years. there appears to be no rhyme or reason for it 20+ runs sometimes less and all the sudden .30 end play in the crank and shavings in the oil.
my driver likes to let the engine sing from time to time( secret is out, lol) also, the trans case has an ultra bell but the rear mount is still rubber(possibly some kind of tail whip effect tilting the converter and input assembly?), converter is neal chance bolt together too.
im open to any idea off the wall or not at this point so any help would be appreciated. thx guys
Travel limiters are recommended also. If the engine/trans is able to move fwd/backwards at all on the launch after the driveline spine locks , there will be force exerted on the crankshaft.
The reactor flexplate is not the problem.
Highly recommend engine limiters if not already equipped.
One per side.
