CAMS.......what a pain..
anywho...I just called Jegs and this is what they gave me,
249-12-402-4 which is a computer controlled (flat tappet)

Computer Controlled Hydraulic Flat Tappet Camshaft
Lift: .444''/.444''
Duration @ .050'': 212°/218°
RPM Range: 1500-5500

I was told by another member to use a roller cam


completely confused
this is just a daily driver, with very slight mods

 

just got this from comp cams
will this work.

there has to be something a little for affordable

some help would be nice

thanks

 

what block are you building up? is it a 87+ roller 350 block? i see you have 88 350 TPI in the headline, so i assume its a 350 TPI motor from a 88 car?

if so then they use a roller cam, and the one that jegs listed there is a flat tappet cam. NOT good

i'd go for the one comp cams gave you. thats a good TPI cam and should work decent with the stock computer and MAF. tune will be in order but you can get by without it for now.

just make sure you get your heads refitted with new springs/such so that the cam can work. that valve lift exceeds stock valve springs on TPI motors
another option is the computer controlled cams 210/220 degrees with i think around either .450 or .470 lift. there is another version with .500/.510 lift but that will also need new springs

Do you have any other plans on this motor like heads or intake swaps?

 

thanks for the info...
heads are going to be stock just re-done, springs, seals, rockers
I don't want anything radical....

but how about some part numbers for the cams??????

thanks

 

heres some good cams for a fairly mild build up. it would be best with heads/TPI aftermarket parts but will work good for now

Computer controlled Comp Cams
XR264HR 08-501-8 212/218 like u mentioned above..good cam

264HR-12 08-302-8 210/220 .480 lift (needs higher lift springs than stock)

This one here is abit milder than the 264HR-12 but is a nice mild TPI cam
262HR-12 08-300-8 206/210 .450/.480 (also needs springs for exhaust side)

another cheaper option could be the ZZ4 cam... 208/221 but .474/.510 lift. it works well with TPI and stock ecm with mass air flow. needs heads worked for springs to handle that lift but its a cheap cam. lots of guys buy ZZ4 crate motors and get rid of the cam cuz its fairly mild. Ebay and the classifieds here are good places for it.

 

okay another question...
If I get a complete kit, meaning lifters, springs, cam,timing chain set.

what would the problems be with going with a flat tappet kit????

money is an issue, but I still really want a respectable driver with no driving issues.

thanks

 

well generally a roller cam makes more power than flat tappet cams... and since the block is already roller block, might as well go with roller cam. In addition, roller cams are better for the valvetrain since the rollers have reduced friction on the cam lobes, compared to a flat tappet. flat tappets eventually where down and need replaced but i'm not sure how long that takes

sure the cams are somewhat expensive but its well worth it. if your that concerned with money on a roller cam, you could try finding a stock Lt1 cam and run 1.6 rockers. or even a stock LT4 NON hotcam. those two are better than L98 cams but still very mild cams.
Else the ZZ4 is your best bet. i seen that cam like new for 100 bucks. you can reuse the 88 roller block lifters if you have them. if not i can see why you want to go with a flat tappet, as lifters are expensive. unless you can find stock ones used or cheap.

as far as converting a roller block to flat tappet, i have no idea... never did that before or read about doin that, but i'm sure it can be done. hopefully someone else will chime in with answers to that.

 

hey thanks for the info.......
well I guess I'll just stay with the rollers, that was pretty much what I thought.....

but hey thanks again, all the info here is great.

 

last question on this and leave it alone

what about this with stock heads

http://store.summitracing.com/partde...8&autoview=sku

 

seems like a nice kit...has everything in it that you need, including springs and new lifters. Do you have the stock lifters? if you do then you dont need new lifters as long as the rollers look good. they usually dont wear out.

if they make that kit with the slightly larger 264 cam, i'd go with it. either way that 262 cam is ok. I just really like the 264 cam for a TPI

 

this is the way i would go. the first link is the whole cam kit and the bottom is just the cam. i have it in my motor and it sounds mean!
