So i went and picked up my 327 today...it was a runner, 2 years ago, had fresh rings 4 years ago, there are brandy new frost plugs all around, its still getting a full rebuild. The heads were changed and are 3986339, 1.72/1.50 74cc 1971-77 307/350, pretty blah i think...use em for a doorstop and buy me some Dart Iron Eagles ! The problem i have is the block is casting # 3782870, which according to my quick research...is a small journal block, 1962-65 Heavy duty but with no clutch mount on the block. The problem lies in the fact that i also picked up my Saginaw 4 spd today...i'm new to the whole clutch thing...is this mount for the clutch fork pivot, i'm going to run a hydraulic setup, with a slave cyl preferably. Is there any reason with the small journal that i can't wind the **** outta this thing or put as much power... 350-375 horse in it ?? Thanks
If you buy a Lakewood bellhousing or some of the stock GM SBC bellhousings have that two bolt boss on it to bolt a pivot bolt to OR to bolt a slave cylinder to. But the easiest way to do it hydraulically is with a hydraulic throwout bearing. Then there is no clutch linkage down below and you just have a line coming out the side. BTW... uh, you'll have no problems with revving the piss out of a sj 327... but depending on how much the car weighs, you might not WANT to rev it much past 5k.... Sam.
What about how this....http://www.jalopyjournal.com/forum/showthread.php?t=92406&highlight=land+cruiser is done...a hydraulic throwout is expensive...and the whole idea of pulliung the trans to fix a problem with the clutch...we'll see how it goes, i have a bellhousing off a 292 somewhere, but obviously with Slides setup i don't need any mounts on the engine. Its just gonna be a model a...2500 or less, why would i not want to rev it ?
Can't help you with the trans/clutch issues, but I know a little about the small journal motors. All of the small journal factory cranks were forged pieces and are supposed to be able to handle a lot of horsepower. There was also a theory that the smaller journal was better...less frictional losses. At the H/P level you're shooting for I doubt you'd have any problems. Those cranks were used in many full-on racing efforts. -Scott
You might check some Chevy II sites. My guess is that is a pretty rare block for a ChevyII restorer. I know the Chevy II specific exh. manifolds were like gold for a while. They sure reved the **** out of the 365 HP motors.
I don't know how available parts are up there at the North Pole. But what you need is either an aftermarket bell housing that has holes to mount brackets on the side. I used an old Ansen NHRA cover from a 348 block. Lakewood, McCloed and others make some now day's. Also the old Aluminum Bell housing from the early Corvettes work well however they are scarce and mostly are **** because of the wear and tear, if you run into one make sure all the threads are good and check for cracks around the starter mount etc. The last one I did I made a bracket out of 1/4 2 X3 tubing, drilled holes to mount to bellhousing and a ball for the ball for the bellcrank unto the tubing. It has over 100K miles of beatring and banging on my Nova. 327's a sweet motor, put into a light weight Car they can produce some awsome acceleration.
You should be able to wind it more than a comparable 350. For one the rotating m*** has a smaller cir***ference and the bearing speed on the small journal is considerably less I'm told.
I'll get the suffix code next time i go to the shop, figure out exactly what it came in, i'd imagine its just out of another truck though, i should call and get the full story from the old ****** i bought it from. I got everything carb to pan minus accessories and exhaust manifolds for $200 CDN, it was his daily driver until two years ago. I have a set of ram horns off of a 56 Apache 3 ton truck as well, it has the front mount SBC in it, the block and crank are probably salvageable too, i'll make sure it doesn't get hauled to the s**** yard. I was looking on the Summit site at the ****tershields...don't have the cash, i have that 292 truck bellhousing that i can adapt, its cast iron but what the hey. I've got a buddy who swears he has an aluminum bellhousing somewhere and I'm going to try to look for a newer 80's/90's truck bellhousing since it has the mounting points for a slave cylinder already and they are aluminum. Thanks for the help guys, sounds like it will all work out in the end...and maybe better...
