Hi guys, could someone comment on this cam? Weekend street machine mainly. Have notched JE's. 3.73 gear. manual brakes. Can I get away with a 2500 stall? Thanks and any comments greatly appreciated, Tom
Nice sounding cam (at the race track)...:bglasses: Old info, may not be up-to-date.... Idle speed 1300 RPM +/- (do you want to do that on the street?) Pulls hard from 3,300 +/- (2500 stall sounds a bit to low for this cam) I think there are better, more well behaved camshafts for a weekend street machine. But if you have an itch to scratch....
You will need a good 3500 stall. 3.73's would be just about right. It's possible to get it to idle down much lower than 1300RPM, depending on how much it's advanced, and having the idle circuit on the carb setup right. This cam has been known to take a mostly stock motor deep into the 12's without much more than headers, deep gears, and a converter, if you can stand the idle (I personally like it). ________ TOYOTA TF104 HISTORY
The old "window rattler"........Lots of power all concentrated in the 3500-5500 range. We ran it with stock rockers years ago and had no problems. Shifted at only 5700. 118 cam made a bit more top end but you had to rev it to 6000 to get it. 107 has a BAD sounding idle....hence the name.
Been there done that. Had a 4000 stall, some good headwork. Headers, 4.10's. Cast piston 9 to 1 comp. at 3500+ feet of air that day, I went 12.18 back to back no problems. With a looser convertor you can make it idle down. I ran mine around 1100 all the time. This thing sounds like it can beat the world when its idling.........got love that .
With a 2500 converter you will need to pop it into neutral at lights but that's pretty common for most bigger cams, anyway.
like he said , need to set the car up for the cam, also you will need at least 10.5 to 1 comp, or it will be a dog out of the hole and never really recover. just my 2 cents
Tom, 2,500 stall won't be e-nuf converter for the 107 cam. Needs about a 3,500. I am currently using a 10"TCI converter, My wife drives/races my "70 GS, it is plenty streetable, Robin has run a 12.20 while leaving it in drive(shifts about 5,600) & I have run a 12.18 while shifting at 6,000 (at about a 100 lbs. heavier ) I also have a 3.73 gear. The car would be faster with a little more converter or more compression (currently speed-pro 10.25) but either would hurt the drivability. There might be camshafts that will make more power, but nothing sounds better then this camshaft with M/T headers, & Flowmaster mufflers :TU:
Like Buickday, I also ran a 12.18 @110 mph with this cam in 1984. 4100 pound car, 4.56 gears, 11" ATI convertor, B4B, 850 Holley, headers and Stinger ignition. That boy sounded bad! Always got looks when we cruised the Inner Harbor or Burger King! Idled at about 1000 rpm with Rhoads lifters. Drove it from the Jersey Shore to Annapolis, MD a couple of times like this! Craig
You might be surprised how good it runs with the right converter, even with low compression. The narrow lobe centers help. I know first hand of a heavy car that has 9:1 compression and 60 foots 1.70's with this cam. It tends to fall off at higher RPMs, but that could be due to a lack of head flow. If you have the compression, I would look at the Poston GS112, which is the same cam as the window rattler but ground with a 112 degree lobe seperation angle. It doesn't have the same sound though- more of an even thump. The 107 has a unique, uneven cadence. ________ Bag Vaporizer Reviews
Yeah, I was running the Speed Pro replacement pistons and with slicks was running 1.7's 60' with a best of 1.7406. (slicks) Craig
107 cam Thanks for all the comments. I'll look for a 3500 stall. I have a couple cams and will give the 107 a try. Trying to make a "back in the day" look and sound for my 67 Special. Things like, Offy 2x4,MT Super Scavengers,Crager S/S wheels,pair of Cal Custom hood scoops,ladder bars. Just some things I've been collecting for this build. These things just bring back memories. Thanks again, to all. Tom
Tom, The 107 is a window rattler, fender shaking monster. I used this cam in my 70 GSX stage 1 in 1990 with MT headers, TA intake, 850 holley, 3000 stall converter, stock 3.64 rear. At the GS NATS, we ran a best of 11.91 @ 111 and back in Maryland, it ran 11.78 @ 113 . It is a little much for the street and I think some newer cam are milder and run just as good. Boy it was fun!
