I figured this section of the forum would be the best place to ask...

This is my first engine build with modifications (I've rebuilt motors but just to stock again after a failure, etc).

I have a sbc350 4bolt that came with this engine kit: http://www.summitracing.com/parts/hly-300-503-1



To further complicate things, the cam and lifters in that "engine kit" are part of their own kit.

The above kit is no longer made and now this one is the current equivalent... https://www.lunatipower.com/Product....d=3838&gid=278


The exact same thing as far as I can tell, just a new part number.

In the last kit I linked, this is the cam: https://www.lunatipower.com/Product....d=2938&gid=278

And these are the lifters: http://www.lunatipower.com/Product.aspx?id=775




I'll spare you all the reason why, but I'm looking to replace the lifters. Obviously, they're hydraulic flat tappets.

QUESTIONS

1. Brand preferences? I'm seeing a lot of Comp Cams and Lunati.

2. Are there any that I'll see/hear/feel a noticeable difference between? This is a car that'll be 60/40 street/track. Probably some auto-x involved.


Here's what I'm thinking...

I think those might work best for this application? I noticed the seat height is lower. 1.93" vs 1.99"? What will this effect? Would I need longer push rods then or?

Thanks in advance for any advice/knowledge you're willing to share.

 

maybe I'm being too conservative but with all the cam break in issues, I would only place Lunati lifters on a Lunati camshaft

 

Just an update on this, decided to buy a whole new kit with the cam and lifters.

Undecided on which just yet.
