I'm dropping a 49 Merc Flat head 8 into an S -10 ch***is. is there any rule of thumb on how much angle the motor can be sloped backwards?
3 degrees is good for driveline, and the late flahead carb surface is machined the same so the carbs set level.
Yes & no. There would be three things I'd think about regardless of the engine or the vehicle it goes in. 1) Regardless of what final intake you use the carb base needs to be level or within 3-4* degrees. carbs don't like to work right at weird angles. use a small level on the carb base to get it straight. 2) the more angled the engine is the more problems you may have with the oil in the pan. Including oil drain back & pump starvation if the angle lets the pump **** air. 3) The angle of the transmission tailshaft will affect drive line pinion angle. They make magnetic protracter gauges that work great. good luck!
Good advice, I would set the engine where you like it and manipulate the driveshaft and pinion to suit.
if all else fails, do a search here before starting a new thread on subject covered many times already
This one, it's the easiest and fail safe so long as you have your vehicles ride height set and car on level surface. Or else the engine angle will change with different stance's and tire combination's of radical change.
I always wondered how the old g***ers got away with all those wheel stands? Apparently that car works fine at WOT How does a car negotiate a parking garage? A 10% road grade is about 6 degrees and you can encounter those for miles and miles and have to pull that grade.According to the bubble level now- That's going to be 9* down on your engine heading up that hill. Engine will be 3* up coming down. Obviously the hilliest parts of the country have area that are more than 10%, how do the old cars handle that. How's a motorcycle do wheelies for miles and miles. So many things to think about now
i used magic in my old plow truck when i pushed snow up long driveways and voodoo in my mower when mowing the back hill.
Damn it now I'll never get to sleep trying to find answers to these questions. But they are good questions. How about thos Joey Chitworths type cars that drive on two side tires for like miles around circletracks? Hmmmm?
Nanny nanny boo-boo If you figure it out, you can just chuckle to yourself when "they" say " it must be 3* down" Extra coffee in the mean time
I used to really stress about ride height/angle when stuffing an engine in then it occurred to me that we used to rake the hell out of 'em and drive 'em without changing the motor mounts. That said if you are building a car and have not yet set the engine then it doesn't hurt a thing to try and get it as close as possible. Set your ch***is up close to your desired end result and throw a torpedo level across the carb pad in both directions before you weld the motor mounts. I am concerned about why they don't have buggy pool lanes in Amish Country.
Mannnn,,, don't get caught in the buggy lane without a buggy. They put you under the jail for that one. So lets say your ride sets kinda level, right ? the engine angle is at 3* The carb is level. The pinion is at 3* Nowww. Lets throw some big and littles at it get a nice rubber rake, maybe some air shocks or long shackles too. ( remember those days ) So the ch***is a raked at that eye pleasing 4* *** up. Well the engine is now at 1* up instead of 3* down the pinion is still at 3* the carb is way off of level and the earth is about to stop rotating because of the paradox you've just created.
Lol No doubt carbs can run at steep angles and some carbs do it better than others. But yeah it's best if you level the carb base when you install the engine
Some days everything seems to be half a bubble off ..... Or as my wife says half a plum out of cherry
