LS1Fleetline

Hey Guys,

I am restoring a 1950 fleetline and have purchased a ls1 out of a 2002 firebird. The motor has 65k original miles and is in great shape. I plan to do intake, cam, injectors and headers. I don't want a monster of a car just a solid reliable fun car. Will a 4l60E keep me happy and be somewhat issue free? Alot of folks have told me to upgrade to the 4l80e but that will require trans tunnel mods and I really don't want to cut up my floors if I don't need it.

Also any tips/tricks or insight on the combo I would love any and all feedback.

Thanks

A properly built 4L60E will handle the hp you are talking about. Anything over 500 rwhp a 4L80E would be your best bet.

4L60e will do just fine, You can go well over 500rwhp with a well built 4L60e. I have a Ls1 on nitrous and a ton on low 10 sec passes on the 60e and a handful of 9 sec time slips, as do many other people.
