The 496 project

I'm putting a 496 together with my friend, and would like to know what a good combo would be for a mostly strip app.

I want a radical motor with about 6-700 hp.

The street use would be a quick run to a local car show not more than 10 miles one way. I want to go solid roller but the horror stories you hear about a SR on the street turn me off. If we go hyraulic, the motor will be whimpy on the track.

I know, I know, there's no such thing as a true street strip motor. I hear this all the time. But this is going to be in a Camaro, not an Impala with car seats in the back.

The 427 that's in it right now pushes about 400 or so. It's fast on the street as you can only go so fast legally. If a show is far, the car goes on a trailer, period.

Any suggestions besides forgetting it? ;)

solid roller are fine for what your doing

Pat,

Thanks for the reply. I have heard from some people that you have to replace the lifters every two years. You CAN'T drive it around at one rpm (like up on the highway). Not that I have plans to, but I may give up and keep the 427 in it. She pushes pretty well and with the old iron 840's for some pump stops. I may go bigger on the carb though. Right now it's a worked 750 DP. A buddy o'mine has a 468 with about the same CR and cam set up and he's running a split dominator. 750 up front 1050 in the back. He has NO troubles whatsoever.

Must be spring fever.

well if you buy good lifters your should be ok it would have alot to do with your miles your planing to run on it small lift solid rollers work fine i would still pull the intake off every now and then take the lifters out wash them look them over . low rpms will hurt the lifters they need oil on the pin so a lifter with hippo is what i would use as well as a good oil

Everyone at the track I talk to with solid rollers check/replace them every two years but they are trailered race cars. I had one go after one year and tore up the motor pretty good but I log about 60 highway miles a week to the track and back on top of the racing. Replaced the comp lifters with isky hippo lifters but will check them this week before the season starts. Been told you should run a rev kit if driving on the street... Keeps the roller on the lobe but costs about 40hp I don't have to spare... If you're going max effort 800hp and street driving you should consider it. If only racing... Check lifters every 2 years.

i have run them on the street for many years if you are not at max rpm on the street . but hi rpm is were a roller shines just can be hard on valve springs. i did drive the cars alot at one time to work and the track . every trip was more then 25 miles one way and did drive the car to the track every now and then but more miles on the street were it was short blast and back down to a lower rpm i run a 1.625 spring isky 9685 with very good luck has well as customers that do run them on the street you have to ask your self how much money you want to spend putting new parts in a 800+hp engine every time to drive on the street the clock will be ticking your wearing parts out . if your just banging around on the $$treets with a springs that are more for drag racing and a lifter that can not have a long life span with weak springs you need to look at them and check them if your engine is a big hp engine and hi rpm then you should look at it every now and then to catch parts going bad. i see no need for a rev kit . i never used one on the street . less your going to run a hyd roller cam at hi rpm . low rpm and low oil splash is what kills them.some cams run tight lash for hi rpm i can not see were more lbs with the rev kits going to help much could add to wear..but if your springs lbs drop then the lifters is going to skip or skid the will be trash . lifter s with big pins and hippo helps if your runnning a big cam like past 700 lift things are going to wear out if your runing past this then no matter. comp lifters are not so hot. i do not know if they work things out . i had seen guys have better luck with cheap bulk crane lifters i would never spend the big money for rollers for me i run the cranes pull them out throw them out buy a new set still be head of the game i have used the crowers hippo . but crane pros hippo as well as the isky red zone are very good. i have used the used take out hippo crowers in builds they hold up well. for my big chief engine i have the crower that i will re work for more oiling to the pin .a very good oil can not be over looked your going to want to change it out alot more as well to

you're probably right Pat, but evryone i talk to says street driving is a murderer to solid rollers. hell, i even know guys who replaced thiers 3 times already while my solid flats are still going strong. (ok, smaller cubes and so, but still)

I may end up refreshing my 427. this stuff is starting to add up to this and that and for a saterday night duster, a 496 is probably gonna be overkill.

the same lift to as yours ? run a hyd roller on the street if for street and some drag racing but for all out racing it solid roller both cams i have now are solid and ones a 700 lift cam in my 548 was in my 462 and the other is a 741/731 276/287 @ 050 and thats in the 632 donovan i run many others as well the small 700 lift cam i used over 8 years :D my 100 over 454 had a crower cam and that i drive all over that was 20 years ago my 462 and 468 i had a comp 680/680 at around 268 @ 50 was EZ on parts as well as the lunati for my 548 14to8 street engine that was a 748 lift cam that had many street miles on it never had a lifter go bad. i built some bbc to:D. from time to time i here about a lifter going bad but i know of more flat lifter cams that did and hyd roller is what i put in all street bbc builds less it a all out engine then it is solid roller:D and now with the hippo lifters i think your odds are better the only thing i can say about the guy you know hard to say if he did every thing rigth ? the way i build them works for me first thing is wash out the lifters in thinner blow dry and let them set in oil before you put them in
