    Solid Rollers on the Street...

     



    Hi All,

    As many of you know I've taken a certain pride in driving my 11's street car to the strip. I knew the day would come wished I had I trailer... first time when I busted a rocker and a buddy offered to tow me with his trailer the next day then a couple weeks later when its apparent I ate some lifters... the baby's in the shop and I'll know the prognosis next week (unfortunately I don't have the equipment or wherewithal yet to do this at home )... Anyhow I'm pretty sure I lost at least two lifters and probably the cam.

    Everything was new in May last year and I've probably racked up a little over 1000 miles street and strip...

    The solid roller cam is great and turns out the power great but it's apparent the lifters weren't up to the task. Comp Super rollerss... Most the guys around here freshen their race motors every two seasons as for going over the top end and checking bearings and what not... but these guys aren't turning the street miles.

    At any rate, I've learned everything needs to be double checked at least every season. I'm going to step up to direct oiled pressurized lifters, probably crowers (thanks pat )... I think I'll have the old lady talked into a new trailer and truck soon we'll see...

    anyways... moral of the story is a solid roller motor is more for racin' and less for cruisin' around (duh!). Check the valvetrain frequently and if you need to adjust the same valve twice take a good look at the lifters!

    -Chris

    Yup!!! That's just another reason I like my trailer!!!!! We freshen race motors every off season and check the bearings and do a leak down at least once a month......

    There's a lot of difference in a summer's worth of laps at the drag strip and cruizin' all the time. The best engine for either occasion will not usually be the same engine!!!!

    hi scooter... yeah I have 4200 stall but haven't had much trouble with the tranny getting hot... even a hot day on the highway usually around 180 but up to 190* tops..

    ratso - glad it's worked out for you so far... do you mind sharing what you're using? What lifters, springs pressures and an idea of the cam? Do you do any special machining to improve oiling to the lifters? like grooving the lifter bores? Any info will help...

    I was using comp super rollers on a .630" cam seat pressure about 240-250# open pressure around 580#... cold lash .017 with aluminum heads

    thanks,

    -Chris

    what oil are you using ? your cam is not that big i have used so many solid rollers over the 20 years on the street some in the 700 lift i have used the crane rollers lifters over the years i been lucky some day my luck will run out . i have pulled the worn out ones before they did any thing. i have rebuilt engines were they were not so lucky were the rollers and lifter pins were siting in the oil pan i have used the 1.625 iskyloy springs in both cars and other customers engines have used this spring many times it 240 @2.000 and well over 650 they work fine i know i have over 1000 miles on the blown 548 in the 50 chevy with crane rollers and the isky springs and 712 lift crane cam the the other engine were in the 680 lift and used crane lifters i have crower hippo that will be going in when i go thru the engine the gto has a 740 lift cam with the same springs and lifters you could look at the new isky red zone ez roller lifters with no needles bearing in the roller

    I think if you are wasting lifters so fast they are not riding the cam correctly. Impact is what will do in the bearings in the lifters; are you using a rev kit to insure they stay down against the cam? Are all the components matched? Are they being lubricated correctly?

    Yeah, racing is tough on parts but I would expect 10,000 mile, not 1,000.

    3000 at best or less with that much spring and you do not need a rev kit KITz

    Pat, are there some mods on the oiling system or the lifter bores to extend the life of the mechanical roller lifters on the street????

    yes you can buy the hippo roller lifters that put oil on the pins or buy the comp tool that cuts a small groove in the bore or buy the red zone ez that do not run any needle bearings

    thanks everyone for all the input... haven't been on much this weekend.

    I'm running 10w30 Brad Penn Penn Grade 1 synthetic blend racing oil (it's GREEN )... no rev kit. Engine guy said we probably want to step up to 20w50...

    Will not groove the lifter bores but going with hippo style lifters... my guy likes the red zones for the style of the bearing as mentioned...

    I'm still in the queue and the old girl will be going under the knife (or wrench) probably tuesday. I'm hopeful the cylinder bores didn't get scored... I'm keeping my fingers crossed she'll be up and running before next sunday cuz I already ponied up $200 for a "high" dollar race on the 1st... I might be running my grocery getter how about 20s SUV against 7s dragster?

    I've heard synthetic oil doesn't work well with roller lifters because it is so slippery the rollers don't roll, they just sit there and develop flat spots on them. Is there any truth to that?

    Interesting... I hadn't heard that. I would like to hear if anyone has more info on that but I think most factory motors now are running full synthetic including all the hydraulic rollers from GM
