: camshaft
rjw3326 Mar 3rd, 05, 11:55 PM im about ready to purchase a camshaft for my 327 and want to make sure i get one that uses its power band right with my stock 2 speed powerglide and stock rear end. Specs for the motor are: 202 Fuellie Heads, 650 HO AED Carb, aftermarket headers, 1.5 roller rockers, stock bottom end, and thats all i know. If you need other info just ask and ill try to let you know. Thanks for the info and advice. - rob
p.s. i bought(and am thinking of exchanging)the camshaft i bought because it has a 300/310 duration and 110 lobe seperation - these im told is a cam built for high rpm that i dont think ill need. Thanks again.
427L88 Mar 4th, 05, 10:11 AM Not only will you not need it, the 2 sp tranny and stock gears will HATE it. You need something around 40 degrees shorter! 260/262 is all!
Any idea what compression will end up at? Any idea what the rear gear ratio is?
the PS is a 2 sp with a very shallow 1.8:1 1st gear. You need torque right off idle to work that tranmission well.
DoN't THINK about exchanging the cam - DO IT! Unless you're swapping to 5000 stall and 5.13s anytime soon.
What manufactuer? I'm sure someone will be able to recommend the right cam in their lineup , to make the exhange easy anyway.
rjw3326 Mar 5th, 05, 12:25 AM i talked to a specialist at crane cams and he gave me the idea of what to get....i ordered a part number 114201 at cranes site. compression will only be about 9.5 or 10:1 and the rear gear ratio is 3.08 i believe. i plan to add a 2000 stall soon and the specialist said he recommends i do. hopefully i get some torque with this new cam. the old cam was a blue racer crane part number 270-WG1064K at jegs site. thanks for the info graemlins/thumbsup.gif
bigjimzlll Mar 5th, 05, 12:44 AM I hate to say it..but that cam is too big too

Too much cam for a 327 with 3.08's
GRN69CHV Mar 5th, 05, 8:51 AM Forget changing any cam at all. Leave the 327 stock and spend the money on a rear ratio change. Get some 3.73's in there-minimum. A swap to a 3.73 over a 3.08 with your setup will be the equivalent power increase to dropping in a 400CI motor. You are talking a whopping 21% increase in torque to the wheels by doing a gear change. Your 327 put out about 350 ftlbs of torque now. Changing the cam with no other major increase in compression,etc will move the torque curve around, but not really increase it. A gear change would provide an equivalent increase to 423 ftlbs of torque. 4.10's would yield the equivalent of a 33% increase or dropping in a motor with 465ftlbs of torque. I run 3.73's with a 408CI big block. Even a mild 327 motor could run a 3.90 or 4.10 and be happy on the highway at 65MPH.
68chevelle533 Mar 5th, 05, 9:40 AM My 68 had a 307 with a glide and 3.08s. It was a stock motor with small 1.5 inch header and a performer intake being the only changes. At the track 2.4-2.5 60 foots were the best it could do. You were doing about 30mph in first gear before the motor really started to work. By installing a turbo 350 and a 2000 stall the car picked up to 2.0-2.1 60 foots and over 1/2 a second in the quarter. If you put the stall in it and have to replce the cam , I would put a more modern cam in it with specs similiar to the orginal.
427L88 Mar 5th, 05, 9:49 AM 300/310 cam's too big even with 3500 stall/T350 and 3.90s. imho. How much do you want to change to run that cam? You'll want only 280-285 seat with any street 327, even if its geared up right.
Forgive me for nit-picking, but cams are nit-picky, imho you *might* have done better with their p/n 10052 here

GRN69CHV Mar 5th, 05, 12:23 PM Gene,
If/when you check back in here, tell then what gears you run behind a 427 big block. I just don't get why the first thing guys want to change when they want more power is the cam. Gears first, then cam.
pdq67 Mar 5th, 05, 8:39 PM Heck that Wolverine Blue Racer cam is the old RPM!!! WOW, not good at all for a 327 motor!!
NO bigger then a Crane 266/266 Energizer and probably a CC 260HE would be better.
OR I bet the Performer cam would work fine for you, imho!! W/B/R's part number WG-1103. It's basically one step up from the great old stock -929 cam in your motor now!!

Slowpoke70 Mar 5th, 05, 8:49 PM I vote for the Isky 264 Mega Hydraulic. But I'm not sure if the 327 will like the 108LSA??
I bet the cam in my 355 would work okay in a 327 too.(I think it is Comp Cams CC252DEH12, not sure on the PN) 252/260 206/212 .420/.440" 112LSA. It runs a full weight 70 Malibu up to 72.5MPH in the 1/8th mile with 2.73s and a TH350.
I think Comp makes it in various LSA's also, I would pick around 110LSA.
The Crane 266 Energizer like Paul state would probably do good in there to.
Mike Feudo Mar 5th, 05, 9:01 PM Think very seriously about a change to a 350 turbo. Glides are fine in 2000lb race cars with a 5000 convertor but not many other places. It's a direct bolt in and you will be very happy with the end result.
rjw3326 Mar 8th, 05, 10:27 PM so if i purchase 3.73 gears and put a th-350 in with a mild 2000,2200 stall what cam would you guys recommend ? thanks for the input im glad i found some people who know what there talkin about. my local store doesnt know a whole lot. also, how much power does a cam actually make in perspective? will u feel the difference? im tryin to keep my chevelle happy and turn heads, i dont want people looking down on it. thanks again.
mechcanic427 Mar 8th, 05, 10:47 PM sounds like what i did back in 73 with my 65ss malibu. wouldn't get out of it's own way till 30 mph in first gear, shifted into drive at 80 or so i think.turned 15.5 in the 1/4 with stock cam and 14.8 with a 220 @ .050 .460 lift, 11 to 1, 780 3310, torquer with accell dual point. went 14.2 with just a turbo 400 and stock converter change.
go get you a well built 700r and keep the 3.08s and add a lockrite posi would be the first thing to do, it will make a world of difference.
