I.e., mine's an LE9 per the SPID. Are you running the ESC?

BTW, you can defer these questions 'til after LST, ha. I know you guys are crankin to wrap things up.

I got the idea when I saw this breather below..I posted a request for information and a buddy said he had one. It's not exactly the same, but it was close enough. I like the look of the high capacity lids so I combined the two.
Through researchI was able to determine hat the motor is an 85 305 HO L69 with the factory mid rise aluminum intake. When I pulled the pan I saw that the cylinders had been honed, but no marking on the pistons to indicate an overbore. I know it has an aftermarket cam, but no idea what the specs are.
