Default Sleeper build. Ls3 manifolds on ls1?
Trying to make a sleeper car . 3200 stall, 3.90 geads, sleeper cam and stock looking manifolds. Would the ls3 manifolds flow better than he ls1 manifolds?

Sounds more like a not well thought out mod list rather then a sleeper.

Ls7's would be the best bet. But for a sleeper I'd still do lts and just throw a good set of cats on it to hide the lobe and smell

Turbo is the best sleeper mod. Yea it has the whistle but slight turbo cam is waaay quieter than any NA setup.

Big cubic inches, cam with wide separation. Friend has a LS3 in a 98 fbody with a mild cam. other than headers looks stock. runs 10.90's and there's still more left.

I have headers on my camaro, and I tell people I have full exhaust.

Until they see my headers they have no idea...

"Oh wow you have headers?"

cam is something like 227-231. If it was a stroker (416" vs 372") it would be going deep into the 10's. And it is running Nitto 555r tires. On factory 16" wheels!
