Hi

just wanted to ask...

i run these rods in my 396 Stroker..

would they work with a "normal" camshaft, or will i have to get a small base circle cam?

thank you

 

why chance it. if you do get a normal cam and it doesn't clear then you can't return it. or grind on the rods. i would go ahead and get a small base circle cam.


but we would still need more info. like what crank you have and what pistons you have. all that good stuff. a 396 small black is kind of an odd number. usually you have a 377,383,406,350.

 

Hi

when running a small base circle cam, its sets the roller lifters deeper in the bore...and since im running an aftermarket block, i must use the retro fit roller lifters with the vertical link bar..

i just dont want that the "oil-ring" of the lifter get out of the bottom of the lifter bore...

 

the only think i've head is people using the +.300 taller lifters. i have a factory roller block and thats what i use. haven't heard of the lifter going down too far. does your block have a raised cam?

it just seems like a lot of trouble to go through for 13 more cubic inches.

 

hi

i already run the 396, and no, no raised cam block...

anyways, the lifters dont go down that far, so i should be safe...

thank you

 

Very hard to predict, for a number of reasons.

Blocks have a significant amount of tolerance. What will fit in one block, may not in another.

Cams are different. "Bigger" cams tend to fit better. Remember, ALL cams are about as "tall" on the tip of the lobe, specifically, if they were any taller they wouldn't be able to be installed because they wouldn't fit through the cam bearings; but since lift is the DIFFERENCE between the tip and the back side, you make a cam "bigger" by making the back side SMALLER, which improves clearance. But, all of the valve event timings change where the lobes are; so there can be MANY variables.

If any rods will fit, those would be among the most likely to do so.

But as cheap as it is to buy a cam on a small base circle and then run the lifters with the oil band higher up on the lifter body (if necessary), it would be wise to consider. Here's a pic of some lifters (these are solid rollers). The one on the left is made for small base circle, you can see how much they moved the oil band upwards.

Keep in mind, if the lifter slides far enough down into the block at zero lift to where the oil band is exposed below the block casting, you will have a MASSIVE internal pressurized oil leak. Catastrophe. And don't forget, you're working with the tolerance of the block CASTING there, not even something as relatively accurate and consistent as machining.

 

I've returned a cam when I built my 388 stroker...summit racing.
