I am replacing my cam and lifters in my 330 high comp., 4 bbl engine. It has 40,000 miles on it but #4 cyl. was chattering and found a worn lifter. I am wondering if I can go with a little bigger cam and keep the stock valve train. Any ideas?

You sure can. With out any other mods, I would only go only slightly more. I would say sonething in the 204/208 @.050 range. Also remember your engine is a 45* cam bank angle, so the cam will have to be speacial order. You might want to get valve springs also. Can't go very much bigger for your converter is stock.

What if you have a sw pitch converter, would that not allow for a bigger cam?

 

I can grind you anything you want on a 45 degree 330.

 

thanks for the response 64rocket. I looked at Mondello for cam/lifter/springs, but they don't specify a cba of 45* or 39* for their cams. There also seems to be some inconsistency on the cba of the 330's in every forum.

 

All 330's are 45 degree to my knowledge. We can do whatever is right for your application.

 

Various companies can do 45 deg. cams on a custom basis. You engine should be 45 deg but you can verify that with two dowels, one in a left side and the other in a right side lifter bore, and check the angle between them. If the included angle is 90 deg. you have a 45 deg. angle; otherwise the angle is noticeably less than 90 and is a 39 deg. block.

Hey 64rocket, it's been awhile but still having some issues with my new cam. I'm running a comp cam, 224/230 @.050. It's for a 45* cba. 486/489 valve lift. I'm also running new valve springs 130/320 spring pressures. This is my second cam and lifter kit I've tried thinking that would fix the noise(every lifter making chatter). I'm just wondering if the noise could be from something else. I have the rocker arm shaft set up, are there limitations with that. Any info about that 330 motor with that rocker arm set up would be helpful.
