Default So...what now?

After a year-long hiatus, the Vette (an '85) is finally back on the road and running better than ever before. Now, of course, we have to try to make it go faster. The L98 in it has a 52mm BBK throttle body and slightly bigger-diameter intake runners. What modification/s would be beneficial to the other mods? Thanks in advance.

don't forget roller rockers.

With bigger runners, you need to open up that base.

Lower it, mount 11" wheels with 335s on it, dump the mufflers, and mount some flame throwers on the tips.

Exhaust mods will give biggest gains to start with. Increase the stock intake flow (K&N, cut lid), heads, & cam will get you good power increase.

Is it possible to change the heads and cam with the engine in the car? I could imagine its possible with the heads, but the cam might be a bit tight.

"Is it possible to change the heads and cam with the engine in the car?"

Yes! Though depending on how many miles are on the engine you may want to just pull it and refresh the engine. A 383 stroker would be good then! It really all depends on your goal for the car and how much you want to spend or amount of time invested in wrenching.
