what's the biggest cam for 1988-89 305 TPI ?
what's the biggest cam that you can install in a 1988-89 stock 305 TPI manual and still have it be a daily driver but get as much hp as possible. The stock cam is: Lift- .415/.430

I have a 305 TPI w/08-302-8 cam in my IROC. Mildly ported heads and get 215 hp/279 torque at the rear wheels with an auto.
I think the heads will be the limitting factor. I'd probably go a little smaller the next time I did it...something in the 220 dur range with .46 or so lift.

Not sure on the LSA, but the computer doesn't mind it at all. Passed NJ emissions with flying colors. I'm also using World Products S/R Torquer heads. The combo is in an '85 Monte SS with an auto trans and 3.73 rear.
Hope that helps!
