Default 1988 L98 Stock Pushrod Length?

Hello all, I purchased this top end kit a while back and the pushrods seem to be really long. I made the mistake of throwing out my old set before checking that they were the same. How long are the pushrods supposed to be? The 1988 L98 has a hydraulic roller cam and aluminum heads, and I was only able to find info on a flat tappet cam with cast iron heads. Any help is appreciated!

Original push rods would have been GM# 10046173. You should be able to find several locations that would ID the length and diameter of that part #.

I saved my stock pushrods. Currently at work but when I get home I will measure them and report back.

My stock ones are 7 3/16. or if you like 7.1875.
I have a complete set that came out of my 86 which is a roller engine with the aluminum heads. I also have a set of 7.250 that are hardened just sitting around.
If you want them PM me.

Hello, as far as I know 1986 Corvettes are not roller engines. that feature was a 1987 onward one. I would assume the push rods are different lengths.
Thanks, ...
