Default Increase HP in 1973 L48 350

Increase HP in 1973 L48 350
(Intros)

I have a 73 L48 350 stock. Bored .30 over. Put new crank in. Added a little more aggressive cam than stock. Added set of flat top pistons. Edlebrock intake. Holley 600 carb. Set of Dart 64cc aluminum heads. Headman headers. HOW MUCH INCREASE IN HP SHOULD I GET?

Hard to guess at this stuff. Youll like it a lot better than the crappy L48 you had thats for sure. Slowest V8 car I ever had even my javelin I had at the time would smoke it.

Why guess at it. Get a Dyno or take it to your local track

Then compare it to factory numbers.

My first choice is the track cheap and fun at the same time

Have you installed them yet?

They arent bad but little biggish for low compression 350

No number it could be anything
Track is your best indicator of what you have, dynos popular
Know its not the answer youre looking for
Dont forget to get a good curve on your distributor
Installing something like an AEM 02 kit from Summit can find power say if it already "runs fine". Neat tool.
