How to make it hook up??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

novajess1972 · 10-31-2006, 03:13 PM

I am contemplating swapping my current 350ci SB for a 468ci BB. What should I run in the 12Bolt? Can anyone recommend using a spool as opposed to limited slip differential? The LSD cost 3.5 times what I can get a spool for. Any thoughts????

I am running a 3.73 with a Lock-Rite locker. Love it.

Is this the best you could do? It takes time to reply, but not a second to just ignore the post if not interested in replying with some helpful. Thanks for the scolding anyway, Dad.

If this is street driven in any way you do not want a spool.
The lock right is a cheap effective locker that will do the job and still allow you to turn with minimal wheel hop compared to a spool. Then you need to address weight transfer with your suspension to help keep force on the rear wheels.

novajess1972 · 11-01-2006, 06:42 PM

Thanks, SSC!!

I ordered the Lock Right earlier today from JEGS. I will install it along with the 468 this weekend if the fellas are game! BUDWEISER works as a bribe. LOL

Nolowrider · 11-01-2006, 09:49 PM

I did my engine swap (sb to bb) all by myself. The only help I had was getting the hood off. Left the tranny in and just dropped the 468 in. You will probably have to remove the valve covers to clear the brake thingy. Are you planning on upgrading the radiator? BBC like a 4 core. Mine runs 185 all day year round.

Its not a daily driver, but I drive quite heavily on the weekend. Prostreet what spool did you use? And does yours make that gawdawful popping sound that spools do? I had one in my 67 El Camino and it drove me nuts

Jesse

glock35ipsc · 10-31-2006, 04:25 PM

If it's not a daily driver, I would go with a spool. But if it is a daily driver, plan on new tires more often. I used to run a spool in my 81 SWB, and went through tires like mad. Driving in town just torn them up with all the turning corners and such.

PanelDeland · 10-31-2006, 04:25 PM

Spool will hook better but is gonna be a pain on the street.The best way to get it to hook up is probably a 4 link.However the basic rear suspension in these trucks (Coil spring) is used in NASCAR.

57sailplane · 10-31-2006, 04:43 PM

just run your twin i beam with rear coil overs. here are some pictures of what can be done with factory suspension. one is of truck the other is of the suspension in the truck notice factory i beams.

JMac11 · 10-31-2006, 05:02 PM

A GM 12 bolt posi with the upgrade clutches and springs will work. Believe me, I have twisted aftermarket axles with this setup and 14x31 slicks.

What a great idea!
Could I see a picture of that set up from the front and back?

lost wages · 10-31-2006, 06:02 PM

i run a spool in mine and if you have popping noises coming from it something done broke, sure it wasnt a locker that popped, they will do that.

glock35ipsc · 10-31-2006, 06:11 PM

Probably was the suspension "popping", as it will kind of get twisted when cornering, but then something it has to give way, or "slip". My 81 SWB use to pop, but it was to springs/perches and stuff getting twisted then POP back into place then twist again......

JMac11 · 10-31-2006, 06:27 PM

With a spool, you are literally dragging a tire around every corner.

*rage'nrat638* · 10-31-2006, 06:28 PM

i have 350lbs of steel plate in the frame rails on my 85 it hooks real hard..

*rage'nrat638* · 10-31-2006, 06:31 PM

one more of the ladder bars and disc brakes

qksilver · 10-31-2006, 06:35 PM

If you run a spool on the street get some cheap narrow tires to run. I had a spool in my daily driver for about 11 months. Drove from Edgewater MD into Capital Hill DC everyday.(0 miles round trip, parallel parking was a pain though

hotrod 80 · 10-31-2006, 06:42 PM

Why noy look into a drop in or lunch box locker like the 4x4 guys use? Just replace your side and spider gears and retain your current carrier and center pin . Should be a little more street friendly . A clutch type posi would be best IMO.

ratrod67 · 10-31-2006, 06:51 PM

I ran a spool in my old 69 camaro. After breaking 2 axles making U turns I got rid of it. Too much hassle. You will end up spending more money on broken parts and tires than to get a good posi type unit.

*trkklr77* · 10-31-2006, 10:12 PM

you dont want a locker on a street truck, to irratic and jumpy, it wont launch as straight as you want for a pro street truck. either a spool or a posi but as said a spool is harsh for a dd nice truck, mean nasty street/strip racer its the ticket. posi is much much nicer and smoother but will give you a straighter launch and wont shoot you off at the wall. its much safer in ****y weather too, a spool can very easily get you wrecked.

i would run a spool but i was given a posi unit by a freind. my truck is also not and never will be any kind of show truck, just ugly and fast.
