L82 upgrade options

Personally I'd just do a 3800 swap. My 97 Monte was 3400 swapped when I got it. Did a few things to pep it up while I was collecting to l67 swap. Once I did my bone stock l67 swap I felt goofy for the work I put into the 3400 lol1 point -
L82 upgrade options

For an easy no fuss swap, dump the L82 & pick up a healthy mid 2000's LA1 engine. There is a noticeable difference in the two engine's output. An aftermarket or reground cam will wake up the engine even moreso. Porting & polishing both the heads & the intake assembly adds to the performance. The L82's were stricken with the small dia exhaust, all LA1 engines were 2 1/2" at the downpipe.1 point
