L48 / l82
Is there a way to take a L48 and make it a L82?
Got a friend with a 1977, he wants to boost its power but didn't know the best way.
Anyone had any experience upping the hp from 180 to something with a little more juice other than doing a engine swap?

In my opinion, the best bang for the buck is installing vortec heads and a Summit 1103 cam. It's a good running combo and not too expensive. I'm told you will end up with around 325 hp. I did it and I love it.
with both of the guys up there. A top end kit will really wake things up. If he has the budget for a kit with aluminum heads, go for it

Basicly the intake, heads (except valve size), block (except main bolts), and exhaust manifold were the same. Used the same carb and dist but with different config.
On The 73 Spot I have a listing of the differences in the L82 and L48 for the '73 year: http://www.73spot.com/index_stats_files/s_compair.htm

and if you do heads , go full roller valvetrain .....
L-48 also has lower compression pistons than the L-82 , and I believe they are cast not forged
so no matter what you throw on top..... the 2 bolt mains should be good ....unless you add a nitrous kit....
