Pushrod length???

Can anyone tell me what the stock pushrod lentgh should be on 85 block using stock 85 shim gaskets?

would they be the same as stock 87's?

or do i really have to mesure with some kinda adj rod??

thanks

I think it was 8.65", I think.... I'd also think that '85s use the same push rod as '86-'87s.

push rods

I/m pretty sure they used the same pushrod. In 86 Buick dropped the deck height to allow the use of composition headgasket.

thanks for the responses gang,thats kinda what i was thinking
that the deck height diff along with the correct year gaskets equates out too same distance from lifter to rocker arm..

If anything has been changed or machined i would check for the exact length pushrod. Has it been decked, line honed, heads shaved or a replacement cam? Any of these can change the pushrod length. It doesn't take long to be sure!! Frank
