It is a lot of work but with LT5's cheap and easy mods just dont exist. The results of porting are quite gratifying, as you can see by the dyno graph there is a solid increase in power across the entire useable rpm range when running the car hard.

![]() Robert, thanks for the opinion on the throttle body. I read some archived threads on the other place from back when Jeff was thinking about it. You're right, if it's not worth anything like the majority believe, then why do all the big names do it.

![]() I was thinking of doing the plenum and IH that are on the car nowas I can't imagine it ouwld be down for more than a few days, but I guess it makes sense to tear into this other motor, do it up, and swap them out in a weekend. Even though I've been told my botom end is solid and should last a long time, I just can't bring myself to tear the top end off and have ANOTHER car that's not running. Thanks, guys!
