Serpentine belt system
Hey guys, so I'm going to change over to a serpentine belt system because I'm tired of messing with these belts. My question is what year model car/truck do I look for? I have a 383 (standard 350 block) but it has a 85 year model 1 peace rear main 400 crank.
I know someone has to have done this swap, what all do I need to look out for? Thanks Bryan

Re: Serpentine belt system
Probably looking at like 88 or 89 to like 98? Dont know off top of my head for sure. You can also get the same setup of a 3rd camaro or firebird. I know for a fact that it would be 88-92 if you looked on those.

Hey G, my son will be going to his Moms Wed. Maybe we'll meet up one day this week so I can get a closer look at your system.

Re: Serpentine belt system
basically there isnt enough belt on the crank pulley... if you have any/a lot of ower good change your gonna have belt slip... heres a picture from alldata. you could also tell from the pictues of my setup how it goes around the a/c alt, ps and w/p.
as far as why you need a new water pump its becuase with a serpentine belt setup, the water pump spins the opposite direction... the water pumps are sometimes called reverse rotation pumps..

Re: Serpentine belt system
PM me your number. I'll call you Wed. If I can get a factory set up done cheap I'll go that route. But I don't have ac so I don't know what it will look like.

Re: Serpentine belt system
The gm factory system comes with all bolts and brackets as well as a new water pump,new alternator and a power steering pump. I believe the system is in the 600 dollar neighborhood w/o a/c and a bit more with

Re: Serpentine belt system
I guess one of the things that worry me is the crank pulley. I know the flywheel for a 400 is different then a 350. But I can't remember if the pulley is. I thought it was. That's why I was wondering which one to use.

Re: Serpentine belt system
the only thing that i beleive is different is the balancer, but when you change the serp kit you have to change the crank pulley and all the pulleys in that case, and you will have to change your waterpump too.

Re: Serpentine belt system
There is a V6 and V8 pulley. I had to change my 4.3 setup to a V8 crank pulley. Everthing else bolted up. Check your heads. If each head has three holes in it, your can bolt on the brackets. All the other holes are on the block.

Re: Serpentine belt system
I'm pretty sure they have 3. They are cast heads. From what I remember, when talking to Marshal engines (the builder) they used early vortec heads and early to mid 80's crank.

Re: Serpentine belt system
Well I don't know what I'm going to do yet. If every thing goes right I might have enough for a nice set up from March.

Re: Serpentine belt system
I have the same Blueprint engine that you have. I bought the Serpentine belt system straight from GM. It fit with no problems.

Re: Serpentine belt system
Why do you have to change the water pump? Do you need the new A/C compressor too or just the A/C lines?

Re: Serpentine belt system
Do you have a link for their system? I wonder if it's cheaper then the March system I'm looking at (349)?

Re: Serpentine belt system
Here is the one I bought. Like was said above, you have to use a reverse rotation water pump. So the really nice waterpump that comes with the motor can't be used. http://www.summitracing.com/parts/NAL-12497698/
