HELP!!!
 

what should i do first my car is to damn slow, stock 10 bolt rear no posi **** gears(no idea what ones) rebuild 4 bolt 350 build with all gm parts edelbrock intake n holley carb , helllpppp!!!!.....350tranny stock

Defenitly get the rear end out of the way. Thats my biggest mistake in my 85' was not getting a reliable and performance oriented rear end.

any recommendations for a rear??

For a 78, I guess theirs tons of things you can do, it should be a little more flexible on choices. Im no expert but I would go with a beefy 12-bolt, and then you wouldnt have to worry about Jack.

12-bolt is always a good idea.

you need to figure out some goals before you go spending a ton of cash on parts.
12-bolts are nice, but for the average to reasonably quick street level car they amount to little more than a weight reduction mod on your wallet. you stock 10bolt is an 8.5, very strong rear.
get yerself a good posi unit, auburn pro series or equivalent, and a set of gears that matches the way you intend to use the car and the power band of the motor.
also, what kind of a rebuild is teh motor getting? build up or just a freshening? mild or wild? have you considered a crate motor?
let us know what the final goals are and the members will help get you there.

later

i want the car for street use, i want it to run mid 11's hopefully outta my 350 if possible without spend a rediculous amount of cash,id liek to use my motor, no crate,......stick woth my stock 10 n do posi n gears or go for a 12bolt???

thanks for all the help

Take your motor and strip it down to the shortblock. Get some vortec heads and Comp Cams XE274 camshaft, Edelbrock RPM intake, 750 Holley DP. Get a good torque converter around 3500RPM stall, find yourself a 8.5" 10-bolt with 3.73-4.11 gears, and buy a nitrous kit... hello 11.50's.

Sounds easy, eh?

i dont want nitrious really well i do but i wanna run 11s w/out juice if possible

9.5 in ring gear 14 bolt w 4:10s
