Will let you know on the progress - thanks.Yella Terra hydraulic bolt on pedestal mount roller rocker set, to suit the Buick Series 2 Ecotec V6/L67 3800 . There used to be a good write up on the swap in the old forum site, but that seems to be gone now. If you are interested in them, I would recommend going with 105# springs and retainers. As soon as I know what parts are going back into the build, I will let you know. I bought one of the last few 1.95 ratio they produced.

The rockers I believe are Yella Terra polished aluminum. I did hear Tommy Glover's car with headers, not too loud, but my wife would not stand for it, have to stick with stock manifolds - maybe I'll port them a bit. What brand rockers do you have? I might be interested. I'm still looking into what caused my rod bearing failure.ġ.) Not unless you plan on going bigger in the futureĢ.) I'd go with OEM replacement, but new ones.ģ.) Mostly everyone runs the stock rockers.įWIW, if you run headers and the stock cat-back, it sounds great but doesn't drone and isn't super loud. I really don't need to go too crazy with this re-build, however since I'm doing this, might as well make sure I do it right and don't want any future surprises.

Overall, I've been happy with the performance of my car until now (officially 13.89 at the track, though with my new better tires, my existing combo was easily capable of 13.70's). If I go aftermarket, might as well go all out with 1.8 rockers, but then 130# springs required - so not sure the extra $500 worth the cost.

With 1.6, I could possibly get away running the 105# springs (already have these). That's about it for performance, but for durability -ġ) With this combo, will forged aftermarket pistons be necessary? Coated or uncoated?Ģ) Will OEM lifters suffice or go with the hi-perf aftermarket?ģ) With cam swap - any experience running the stock 1.6 rockers with this size cam? The overall lift will be a bit more than with my 1.95 rockers. Might possibly drop from a 3.4 to a 3.3 pulley. Not planning much head work except for basic rebuild, possibly port matching. This would mean my 1.95 rockers might have to go on the market.

That being said, I'm debating on swapping the cam for the Intense 1X. I'm not planning on going too crazy on the rebuild as I intend to keep the stock exhaust manifolds (my wife is very sensitive to sound). The L67 series I uses a Floating wrist pin and a piston that coated from the 2nd ring groove on up. If you choose to do an L27 youd have to get the rods for the series I. so the 元2 rods will not work in the series I as the 元2 is a series III short Deck motor. OK, pulling my engine & trans for an overhaul. The 3800 Series I is a tall deck motor( Long Rod 3800 ).
