Cam wear

Another thing, you need a minimum of 130 lb valve spring at installed height for a roller cam.

 

Those V6 rollers lighten the valve train over the longer, linked lifters. Might be be nice on a 350.

 

Good choice on going roller!
As Jim pointed out the 335 is for the blank core, you still have to pay for the grind, its an expense, but worth it.
On the lifters, dont dick around with trying to save a few bucks, call TA and have them set you up with the JOHNSON roller lifters, the Morels are GARBAGE!
When I went roller with my 350, I had the Morels, they took forever to pump up, then they'd bleed down, pump up again, bleed down, it was random, I called TA and ordered the Johnsons, quiet as a church mouse! Even after sitting long periods.
I spent over a grand on roller lifters, The JUNK Morels, then the AWESOME Johnson lifters.
I hope others learn from my experience.
The Morels say TA Performance on the link bars.
The Johnsons have the black on 'em

 

I agree with Mark. It’s the same direction I went with my 350 build.

 

215's must be shorter than 350's...

 

The Johnson link bar will work in the 215. The Morel oil hole is too high like the Chevy. The V6 lifters are like the factory setup in newer motors but unfortunately there is no cheap factory roller cam like in other motors.

 

Has anybody put a roller cam in a 300 or 340?

 

Okay, so if I work out a spider, the Chevy 3.1/3.4 roller lifter works; or go with the link bar Johnson’s.

 

I would also have the camshaft fit to use the bronze spacer for the wear surface against the front of the block.... if you are going to use the roller cam
