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 crap 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 shit 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 crap 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 mass has a smaller circumference 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 bugger 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 scrap yard. I was looking on the Summit site at the scattershields...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...
