Thread: 454 valve float

i think your going at it the wrong way the rockers are not going to help the lifters are to heavy that is it .spending money on the rocker s is no going to help the weight of the lifter you can buy a rev kit for hyd roller cam from isky this help keep the lifter on the cam with out added lbs on the pushrod it puts it on the body of the lifter the shafts may be a better way to go do not think whey will help . you do not need them for this type of build your wasting money put a revkit in it and it will do what you want .there is no need to run the poly-locks just buy new rocker nuts they should work just fine with the rocker you have or buy two set of thick valve cover gaskets and run then two a side on the valve covers i used studs on the stock covers to help keep the gaskets from moving i have run over 600 lift this way with stock covers and poly-locks. if you go tapper pushrods shaft rocker titanium valves this would help and you would still need the rev kit ? lifters are still way heavy

Thanks, Pat.

I hadn't thought of a rev-kit - that's a very interesting idea. But, I looked up the Isky site and they don't seem to list one for a BBC. Comp Cams do, but say it's only for solid rollers... It is possible to use a rev kit with hydraulic rollers, is it? Wouldn't they tend to collapse the lifters?
Can you steer me in the direction of an actual part # from any of the manufacturers??

you can use one they do this on boats. no it will not collapse the lifter like i said you are putting the added pressure on the lifter body not on the pushrod i will see what i can find my isky book is at my shop

Yes, I get it now, Pat! I'd be very interested if you can turn up a part number for me.Thanks,
Chris

they have a hat that the spring sets in if your lifters have a full round top to them and not a cut a way lifter or the bar bolt or rivet is not in the way so the hat will set flat. if they have a full round top then the hat will set in to the id of the lifter body so you need to know what lifter s you have if you buy a rev kit you may have to turn the od of step of the hat down to set in the id of your lifter body. so any one can sell you a revkit you just need the right hat to fit in your lifter body .i will look at isky but i need to know who s lifters you have

Pat,

I have Lunati hydraulic lifters, link-bar design, not the pop-up type, #72820.
