Best cam choices?

Looking at a few Comp grinds right now

224/230 with 536/544 on a 114LSA custom grind

also the 220/230 at 510/510 on a 114LSA in catalog

Lingenfelter blower cam with 215/220 with 540/540 on a 114LSA

All grinds using 1.6 rr which I already have.

Looking for choices or other stuff I havent found yet. yes I called Comp and two dofferent answers two different times :-)

Keyword is everyday street here.....

thanks and later

LPE 219 is sweet in a 383, I wish I'd never sold mine, 17 inches of vacuum, idle at 750 with a slight chop, great bottom end.

 

Check your PM

 

Judt looking for more ideas, since no one can give me a direct answer lol :-)

shooting for somewhere in the 220-230 range on a 114

That 219 cam does not seem bad at all :-) I know it works

 

You need to pick a cam for the TPI setup or pick a cam for the stealth ram setup. You are going to wind up with an overcammed tuned port motor and an undercammed stealth ram motor if you pick something in between.

 

yep!

I know that :-) Be happier with a smaller cam in a 300+ miles aweek driver anyhow :-)


Just trying to see what everyone else is running

Cant believe this one hasnt had some more replies, between the LTR and future Stealthram and boost :-)

And the whole daily driver factor :-)

Since all heads flow less on the exhaust side normally, always go for a dual pattern cam for a boosted/nitrous motor.

I personally think something in the 215/225 to 220/230 range is optimal for your combination - not too much duration to cause idle problems. Keep the LSA at 114 to 116 degrees and get as much lift as you can get (as long as your springs don't bottom out). I would also suggest a AFR Rev Kit and a stud girdle (if you can get it for Vortec heads) for valvetrain stability.

 

3.8trans-am,

if you decide on the lingenfelter "blower" cam i have a brand new one plus matching double valve springs that i would sell for about $225.00. my engine builder wanted a bigger cam than that for my set-up (also a supercharged 383) so it never got used.
btw, the cam specs i'm running are 226/234 -112lsa.
730hp@6200 & 700lb ft trq@3800 at the flywheel on 100 octane and 9lbs. of boost

if interested shoot me an email: z28cam2289@aol.com

Thats pretty stout for only 9lbs of boost. What are your engine specs? blower? heads?

 

biggtime,

to answer your questions here is my set-up with just the major pieces:

'87 350 truck block bored/stroked to 383
4-bolt mains w/billet steel caps (center two are splayed)
vortech t-trim-9lbs. of boost (can be pullied to 25lbs. max)
superram intake
1000cfm throttle body
36lb. injectors –––– YES 36lb.!!
afr 210cc race ready heads/ have been o-ringed
cola 4340 forged crank
manely 4340 h-beam rods
je flat top pistons
isky cam - @.050" 226/234 / 112lsa
big double valve springs
ti retainers/keepers/locks
comp cams chromoly one piece pushrods
manely severe duty valves : 2.08 /1.655
comp cam hi-tek stainless steel rocker arms/ using combined ratios of 1.6&1.5
comp cams stud girddle
stewart water pump
canton road race oil pan
milodon oil pump

i'm currently switching from my 730 ecm over to the 749ecm from a 91 syclone to help with a tuning and drivability issues. wish me luck!

 

Im hampered by the 300 mile a week mark this car will have to drive in :-) Everyoen from Crane to Lunati has been suggesting mid 200 teens to mid 220's for a cam.(empahsis street)

think im going for the 218-222 intake and 224-226 on the exhaust and even keep the lift at .525 or under. Mkae it alot easier for extreme mileage.

Not crazy :-) But car travels 80/94 in chicago area to and from work. has to idle for 3 hrs straight as well as bumper to bumper and all the other fun events and be civil while doing so.

I truly dont think going with a smaller cam is goin to hurt me any , especially once the turbo setup is put together im looking for 12-16psi intercooled
