TA Performance 455 Timing Covers roughly $550.00 is absurd.

Hi I like to know what a good camshaft for a 455 Buick boar 30 over 400 trans can I run a double chan with stock timing cover

[@mr.roddersneighborhood2740]

You can run a double roller timing chain from roll master but they are expensive. I’ve had good luck with Edelbrock single rollers without any issues. As far as a cam goes, what’s the purpose of the engine, type of car, gearing and your compression ratio?

[@bbb462cid]

Why don't you call the guys at TA Performance, Karl and talk to them about cams? TA isn't for Trans Ams, they are Buick guys. I loved every cam I got from them. Double roller was no issue on my own Buick 1974 block 455 with factory timing cover or aftermarket from TA but I liked the TA unit a lot. They also offer adjusatble oil pumps with thrust plates. You can also get their timing cover and oil pump setup all in one package, Highly receommend and I don't even own a Buick any more. Buick 455s oil poorly. make sure you get the psi you need.

Dallas. What is your opinion on using a thinner oil such as a 5 w40 instead of a straight 40 or even a 10:40 or 10:30 for the large Journal 455 engine. I remember seeing a report what I ran a NAPA store some years ago from Castrol saying that a lot of the newer Vehicles we're going to dinner coils for quicker lubrication on Startup. This would seem correct in that on a large Journal engine the oil would feed through faster and lubricate better on cold start up. Would like to know your opinion on this. As I know most guys using thicker oil in the Buick because of the style of pump gears

[@tombrown879]

Thinner oils. Not dinner coils. Hahaha

[@mr.roddersneighborhood2740]

That's exactly what I did to my 85 Suburban with the 455 Buick. I run Rotella T6 5w40 just for the purpose for easier and quicker lubrication upon startup. GM calls for 10w30 in all Buick engines and factory tolerances are fairly tight. I prefer lighter oils unless its a heavy load engine, I.E. Tractor, Truck, Tow Rig.

@@mr.roddersneighborhood2740 thanks for the backup confirmation.

[@neilstanich7870]

seem to be very simple but important mods, wonder why the gm techs didn't do that from the factory

[@mr.roddersneighborhood2740]

Took too much time and time is money... probably the simplest answer.

[@bbb462cid]

"GM techs" had nothing to do with it
