Re: Who makes the best timing chain?
MEXJOE,
.050 is tight on ex,if anything goes wrong like say dowel pin breaks in cam or chain got loose/stretched it will get ex valve will get closer,in will get farther away.
Also when valvetrain is loaded(spring pressure) piston to valve will changed some,ex will lose clearance and in will gain clearance.
If this is bracket engine I would shoot for around .090-.100 clearance,this is safe number.
Yeah you can run less,but have to do so carefully,when on the edge you can fall off.
Hopefully you got lucky and did'nt do too much damage.
