I have been looking into converting my stroker into a solid roller setup for a few months now, have done some searching and still have some unclear/conflicting info on parts.
I guess my first question would be about the cam specs for my setup...i dont know much about the cam specs on a solid roller, so i was wondering if you guys would help me pick one out. Most of my mods are in my sig, im not worried about emissions, dont want to spin more than 6500, and want to spray 150-200 shot of n20. This is not my every day driver, it is probably driven on the street 100 miles a month just to take it out, and is trailored to the track. I would like to get a pretty wild custom ground cam, but not too wild where i'll have problems all the time or have to run extremely stiff springs with high seat pressures. which cam sizes have you had/heard do well at the track?
I plan on going witht he comp cams endurX solid lifters because they are supposed to work without any machining done to the block, but am unsure about the valve springs...i was thinking about going witht he 943 springs, seems like a good spring that lasts around 12K miles. Any experience/suggestions
on these?
I called comp cams and they werent really too much help, mainly because i was unsure on a custom grind cam, but they recommended a 286/292, .576/.582 (with 1.5rr's)off the shelf cam, and the 977-16 spring which seems kinda low to me with 155 lbs of seat pressure.
I wanted to clear up a question about oiling the cam and lifters. Some say not to let the car idle long at all, and some say they drive their solid roller setups everyday in traffic with no probs. I know that idling for long periods of time isnt good with any high performance setup, and i know it depends on a lot of things such as spring pressure, oil pressure, and idle RPMS, but is it a major concern with the solid roller lifters? If so, what are some ways to help the oiling problem?
Is it best to run non-self aligning rr's with the solid setup? if so, do the lt1 ad lt4 heads need any machining to run guideplates? Thanks for any help given

For the record, if you're not going to turn more than 6500 rpms, a solid roller is a waste of money. Get your self a Comp extreme cam, as the ramp rates rival solid roller cams. But you'll still be able to run hydraulic roller that way. Get yourself some Comp R lifters and 140lb valvesprings and enjoy not having to adjust the valves every 3000 miles.

 

Ditto. No need to complicate your life with solid rollers on a 6,500rpm setup. I picked a solid roller only because I was looking at a 7,400rpm redline.

I do enjoy the sound of a solid roller.... but you will have problems with your knock sensor (mine is deleted) and you will have the issue of periodic lash adjustments.... maybe every 6K miles.

 

on solid lifters they need adjusted every oil change or 3000 miles depending on if you race it alot then you want adjust them after every couple runs. hdy lifters will run to 7000 limit.

 

Call someone like cmotorsports, or cam motion to spec you a cam. That is what they do for a living...

I used the endur-x lifters and 943 springs and liked both.

And yes you will need non sa rockers.

 

Thanks for the info guys. I'm not really set on not spinning the motor past 6500 rpm, i just figured it would be best for the stroker to keep it around that for a redline, plus i dont have the ignition upgrades to spin it past 7G...I think thats about all teh factory computer can handle, right? The main reason I was wanting to go solid was the horsepower up top, ability to run a huge cam, and the badass sound like Injuneer said...just looking for a more wicked setup. The GTP6 is a great cam (235/242, .568/.592, 112) and i turn some good times with it, but I just want more. Ill give the places kmook mentioned to look into a bigger Hyd. cam
Any info, thoughts, or experiences with poor oiling of the cam/lifters at low rpm with the solid roller?
kmook, If you dont mind me asking what do you spin your motor to, and is it a stroker? thanks for your opinions

That motor which had a solid roller in it was the stock bottom end, the bottom end went on it before i got any #s or times, etc. I then went to a 383/hyd with a blower.

 

solid roller useless with only a 6500 redline? FROM WHAT IVE HEARD ON THE BOARD- Better idle and more top end power, im guessing because the advertised duration is very close to the duration at .05 so you get a calmer idle and better low end but have the larger duration of bigger cam if you were just looking at duration at .05 and smaller cam if you were looking at the advertised. So you can have more low end torque and high end torque then even a very fast ramp rate hydraulic and not be limited to the lower rpm tolerance of the fast ramp hydraulics right?. Now for some it may not be worth it to adjust stuff like lash every 5000 miles or whatever your setup requires but as far as the torque curve goes there is an advantage to a solid cam. I mean running high rpm's seems to be just one of its advantages not the only one. Im no engine master so if Im wrong correct my mistake if ive made one

 

Get a good set of lifters that are oil slotted and you will be fine in traffic. Just remember, buy price pay twice. Get the good stuff the first time.
