hi there i was just wondering if a turbo 350 would be hard to put on a lt1 and this is a car that is driven on the highway almost every weekend, what would i be revving at with say 4.10 gears and does it hurt anything if i drive almost everyday with a manual valve body thanks matt

Not having OD will suck. I didn't like 4.10s in my A4 with OD. What size tire will you be running?

Man you would be running at about 3700 to 4000 RPM @ 70mph with 4.10s on a 26" tire.

That is assuming no slip at the converter and reality is probably a good 4% slip or more meaning 3900rpms.

You need to get a 28 inch tall tire on it at the VERY least to drive around on.

It will wear the engine faster turning those kind of RPMs, get a good trans cooler on it.

I am considering the same deal but mine is not daily driven but with a 3.70 gear and a 28 tall tire.

28" tire and 4% slip and it is still 3600rpms at 70mph. Seeing as you will probably still want a 3500rpm or so stall I would expect slip to be more than 4% that is just the default on the calculator I use.

My cousin has a 80 malibu with a 358 with a TH350 behind it. & 4.10s. At 70mph he was turnin around 3900 i wouldnt put that kind of wear on my car
