Morning Everyone, Well real quick i have a 1952 chevy sedan. I want to airbag it in the next year but for now i have gotten a s10 rear cut the perches and i am going to run 4 inch blocks. I am centering up my rear end tonight and going to set my pinion angle and weld the perches on can someone tell me what angle i should weld this at. The inspector is coming the first of the week and this things needs to be rolling.
Not sure yet i am not pulling the original engine till the inspector leaves since the vin is on the original engine. but i am going to run a 350/700r4 with ch***is engineering mounts for the engine and trans
Do a flippin' search! I've answered this in detail a dozen times myself. Say nothing of all the others...
Use their kit an zero on the rear. Unless you use lowering blocks then you'll have to use someone else's opinion.
whos kit? i am using 4 inch blocks i am just trying to find someone that has done this so they can give me a quick answer thanks.
the same angle that your engine and trans are, is the same angle your rear end should be. ive never heard of a vin number on an engine.
with the car at ride height your engine intake carb mount surface level side to side and front to back your output shaft will be at 3* down from horizontal. set you pinion at 3* up from horizontal. pretty straight forward. edit
Install the engine so that the mounting surface where the carb is installed is level front to rear and side to side. This will give you a 4 degree down of the crank centerline towards the rear. See picture from Chevy Shop Manual below. The rear axle should be installed so that the centerline of the pinion shaft is parallel to the centerline of the crankshaft. This would call for the pinion shaft to be 4 degrees up towards the front. The side offset of the centerlines is OK but they should be parallel to each other. The above is for street application. Drag Race application would have the pinion shaft centerline down and not parallel to the crank centerline because of rear rotational forces under hard acceleration.
Looks like the pinion angle question has been answered. As for the VIN on the engine comment, I'm not sure if it was called a VIN back then, but on virtually all vehicles way back when, the number that matched the ***le was the one stamped on the engine. On some early cars, there was also a frame/body number, but it had nothing to do with the ***le number.
4" blocks arent a good idea. Scrubline violations first off, then add the leverage increase that the axle has over the spring and you got a recipe for disaster.
CARLOS8A you have exactly what i have what did you set your pinion angle at you will help me a ton thanks!!!!!!
Also can you email me some pics of your car i like to get ideas thanks. Send me all the pics you have of your engine compartment and everything. Also what brakes are you running disc in the front, new master cylinder booster? let me know thanks.
http://www.jalopyjournal.com/forum/showthread.php?t=388174 here you go this is my build thread...... as for the pinion angle I set my motor in and then i set my rear end up, The motor was set at 0 degrees and so I put the rearend at 0 also.. still runing all stock suspension and brakes!!! just rebuilt the master and everthing else is new.....
Nice to see someone working on the same thing i am. Is there any way you can take a pic of your trans-mount i was thinking of making one also that can go in and out if i need it to. I am guessing just some square bar tubing and some spacers to get the tail shaft at 0 degrees. One more thing can you let me know what all you did to swap it to 12 volt. I am going to run the factory wires but i will have the alternator and i have already swapped the headlights out. What else needs done? What parts do i need to buy
I am not sure if i took any pics of the trans mount that i made but its pritty easy. yeah i used square tubing. with the mounts and the trans mount i made it set the tail shaft of my trans at dead zero! I redid everything!!! wires,bulbs,sockets,new fuse block new bulbs all of them...... there are tons of threads on here on these cars all you have to do is search thats what i did is search search search........ i know tugmaster on here has pics of his trans mount.
