roller vs. non roller block

DJKING · March 28th, 2007, 04:26 PM

newbie just trying to get some answers. what is the difference between the two?
should i avoid a non-roller block?
can you turn a non-roller into a roller?

I'm looking at a shortblock 351w non roller block. am i limited with this block.

it seems all the performance heads are for roller rockers...what kind of heads would i have to buy?

thanks for the help....

They have a retro-fit kit that's very pricey. But I've seen some massive, sturdy power made from non-roller blocks but the power curve will be different. I would look at a retro-kit or see how you can PROPERLY change your non-roller cam and lifters, to roller.

Roller blocks are blocks that had factory roller cams. They can use factory lifters and hardware. Non roller blocks can still use roller cams but you either need to get a retrofit kit or buy aftermarket roller lifters. I prefer the older non roller blocks because they are stronger. Newer blocks have alot of "corners cut" to cut costs.

You can put roller rockers on any heads. Buy the heads that fit your combination and then buy roller rockers for that particular head.

I got that retro-fit tips and other from Darrell as well, thanks to him I also verified that the 351 I looked at IS a 351. Haven't run the numbers yet so I can get the year

You said the same thing when i asked about non-roller and roller.... Watch what darrells gonna tell ya

DJKING · March 28th, 2007, 08:07 PM

so will a new roller cam be all i need if the heads come with the roller/rockers? Will the heads bolt up fine to a non-roller block?

Thanks

Yes the rockers have nothin to do with the block, And yes the heads will bolt up if they are for that motor. Do you know what a rocker is?????

DJKING · March 29th, 2007, 11:37 AM

obviously from my question Im somewhat confused as to what a rocker is.
I thought I understood and then came across non roller short blocks. On a
short block at what point does it become a roller block? Yes i'm knew to all of this and just trying to get well informed. I appreciate the help.
