Newbie here, my 19 year old daugher just inherited a 1994 V6 3.4L teal green Camaro from her late grandfather. The vehicle has a leaky/rusty exhaust system, so I ordered the Flowmaster cat back setup. Also, the valve cover/gaskets are leaking, so while I have the covers off, I'd like to swap in some roller rockers. I have some old Comp Cams rollers from on older 350/5.7L SBC, also have some stock rollers from a 2000 Buick LeSabre 3800 series II engine. Will either fit/work. The Comp Cams rollers are 1.6 ratio, not sure what the stock Buick rollers are (ration wise). Any help/suggestions welcome. Thanks!

 

5.7 & 3.4 are different part numbers so i dont think they are the same. 3800lll are on a shaft so they are not the same. could do some searches and see if any are shown as fitting on both. better off sticking with stock.
