I'm curious if the lightweight pushrods INTENSE supplies will work for my application on an L27. Or are the pushrods in an L36/L67 Series II in an entirely different world?

Measure your pushrods and see how long they are. I have a feeling they are the same. Maybe someone on here knows off the top of their head how long L27 pushrods are? I could measure them, but my sister probably wouldn't be very happy with me pulling the front valve cover, a rocker arm, and pushrod out of her car, so I am hoping someone else knows. I believe intense says on their site how long the L67 ones are...something like 7.1".

If worse comes to worse I can pull one from a Buick at the local junkyard or pay a couple bucks for one at the dealer, but yes I'm hoping someone knows the length.

Would it be in my chilton?

I know Shucks (Kragen) has them in stock for an SSEI (at least locally they do) so I wouldn't doubt they have them in for an n/a. Have them pull one from the back and measure it, or maybe they even say on their computer how long they are.

Who is Kragen?

Is this your source?

Kragen is a store, same as chucks, or checkers, just diff names in different areas. Same lineup and design and everything.

hehe....1993 SSEI = 7.965" Overall Length

From Intense:
"All INTENSE™ 3800 Series II High Performance Pushrods are sold only in 7.05" (stock) length and sets of twelve."

So that means the final answer to your question is, no they don't fit.
