Crower Level 3 or TA-284-88

About to pull the trigger on a new Cam for my 1970 Buick Skylark

It has the 70 350 originally 2bbl

Now has a 4bbl intake and sniper EFI system.

M replacing the cam due to a bad lifter, might as well upgrade the cam.

I want an easy cam swap with a good sound and decent power increase .


I don't want to get into the heads yet since Im going to be buying some ported ones in the future.

Which cam would go best with my 350 with stock stall converter and open rear 2.56 gear. I don't mind the rear gear at the moment since I daily it from time to time and is planning a road trip.

Thanks guys

 

I am not a SBB expert, but I've built a "few" different engines and cars. With that high of a rear gear and a stock converter, you're going to want as "mellow" of a performance cam as possible. I'd go with the Crower from looking at the specs. Normally when you get over 220 degrees at .050 it's time to start thinking about a stall converter and some gears. Overcamming something makes a car not fun to drive, even if it's cool to quote big specs and listen to a lopey idle.

 

Thanks guys, I'm guessing I won't really need a valve spring change either with this cam? I narrowed it down to these two and I even thought of the 212 but I wanted something with a nice Lope, but I Definitely
Do not want to over cam it.

 

Lastly should I make the jump for a double roller? Or a stock replacement timing set should be fine?

 

I will defer to Larry or someone else about the springs. I'd do a roller while you're in there.

 

Sounds good! I am just trying to see if there is a way to replace the springs without removing the heads. I've seen someone use a compressor to pump air into the cylinder while using a tool to remove them, doesn't seem to bad but don't want to drop a valve in as well haha

As far as degreeing the cam someone mention 4 degrees advanced which will be marked on the new double roller I'm assuming

Thanks guys , I have yet to do a cam swap, just timinnf chain replacement

 

Pull the spark plug, feed a couple feet of rope into the cyl, then rotate the engine to bring the piston up and hold the valves closed

 

You guys convinced me to change the valve springs. Stock replacements? Or is there a recommendation for the Crower level 3? I might as well order them together haha

 

Changing springs is not so easy if you have a giant AC box on the passenger side.

 

I do have have the AC box -_-
