I would make the carb level, if the pinion angle is 5 degrees down with the carb level I would say its ok. I think its supposes to be 3-5. you may have to make your rear ends pinion angle match the ******s angle. the rear end is suppose to be pointing up the same amount the trans is down. so if the trans is 5 degrees down the rear should be 5 degrees up. this is to prevent u-joint bind.
X2 on leveling the carb flange. Whatever angle the trans shaft ends up at is correct. Be sure the car is at the correct ride height (rake) when you check this.
I know this is real basic, but when are these measurements made since all things change once wheels and tires are added.
If you know what tire combo you are going to run, mock the frame up at the correct height for those diameters. The wheel and tires sizes HAVE to come first when figuring this kind of thing out. If you don't have all the components to get the correct weight in the car, you are going to have to pick an axle to frame clearance front and rear, then mock the axles up on stands at the midpoint of the tire diameter (14" for a 28" tire, for instance). This will simulate the finished ride height and rake. This is hardest with stock type buggy springs, as there isn't much sag or way to alter the spring height. MUCH easier with coilovers...but we're not gonna go THERE.
Just make the sure the output shaft shaft of the transmission and the pinion shaft of the rear differiental are parallel. This will make the driveshaft happy and it could care less if the car is going uphill, downhill, or around a banked turn at Daytona... P.S. Do a "search" for "pinion angle" on here and you'll get 496 threads... That's a lot of BS to look through...
Most, if not all intakes have a 4 to 6 degree angle built into the carb mounting pad due to the engines originally being mounted at a rearward angle. You should be fine.
...interesting that 'alt 0176' does the same thing...must have been an edict from the Dept of Redundancy Dept... Oh yeah...5° is ok .
