Retrofitting an elderly block to a roller block

GreenMustang00 · January 28th, 2012, 02:35 PM

I know I had a lifter/Valvetrain thread a while back.

Anyways.. I have a 80-83 block and looking to retrofit the block.

My main question is "If retrofit is essentially the same as link bars" I am looking for a solid roller kit. Either I am blind or there aren't any comp cams "retrofit" lifters that are solid roller. I fould a set of Scorpions but am clueless on the reliability of them.

Any links or recommendations as to them. The max lift on the cam is .680

Just use linkbar lifters. That way you don't need to do anything like drill and tap the block and use a small base circle cam. Just use any roller cam you want.

Ok re-reading, I missed the question. Technically retro-fitting involved what I mentioned which is drilling and tapping the block, using a lifter hold down and dogbones like a stock set-up, and a smaller base circle cam. Using link bars will allow you to put a roller in a non roller block as well but I don't believe they refer to it as retrofitting.. could be wrong. Either way, link bars are the way to go. There's tons of solid link bar lifters to choose from. I would post links but am using the phone.

Thanks.. Retrofit lifter kits appear to be a pair of lifters with a non-adjustable linkbar. Nothing to do with drill and tapping

agreed

you would need to retrofit the block for the dogbones and spyder that holds them cause a hydrallic roller lifter does not use linkbars but if you are going solid roller that is just a new cam and lifters. dont skimp on valve springs ither.

I got valve springs exactly on spec for the cam, as well as retainers and rockers already. Just need lifters and pushrods.

comp solid rollers would be a good choice

How about Howards, Or Lunati. They are a tad cheaper.
I know you get what you pay for but doesnt hurt to see how people have done with them

Edit: just read bad reviews on both. These are the comp cams

Are you running this car on the street? Take this for what it's worth because I've never run into this personally, but a pretty respected builder told me this, solid rollers can have trouble idling. Apparently the pin oilers don't get enough pressure at idle and the bearings can wear prematurely and fail. I don't understand why that is personally, but this guy builds a lot of fords and I tend to believe him. I asked him about crower hippo lifters (hi pressure pin oiler) to see if maybe those helped but never got a response to my question. At the same time, I've seen a few guys run solid rollers on the street and never complain about a failure so who knows. I haven't looked much further into it because I don't plan on running solids for a while yet now, but it may be something worth checking into before you buy.

The Crower setup seems to be the best way to go for solids on the street. Something about the way they're oiled or something. BUT they are $$$$$$$$$

Fogged,

It will be a street driven car, about once a week. Lol. A few buddies are running solid rollers and have never had a complaint from them. I will look into that more.

Indeed they are, what do you run for a lifter?

Mine are hydraulic, and in a roller block. I run a stock style setup, with some comp lifters.
