new crate motor, which pulleys and waterpump
 

swapping my 71 6cyl. w/P.S. for the gm350 260hp crate motor, gong in the v8 position, not sure what all im going to need as far as long or short waterpump, will my 6cyl. fan pulley work with the v8, do i buy a dampner with pulley grooves already in it? will my 6cyl. Alt. and P.S brackets work on a v8., also any suggestion on running with or without headers on this motor, whats a good reasonable price header that would fit right in. i also will be using a eld. carb. and manifold and putting in a 4 core radiator. any past experience help out there would greatly reduce my trips to the part store and would be much appreciated. THANKS

SO....
WHAT YEAR TRUCK...
A/C ....????:confused:

re-edited 71 c/10 no a/c.

well i really have no clue about the 6 cyl pulleys....


but i will get us started here

short water pumps are the stock pump for early trucks....
much easer to find also....
balancers don't come with pulley grooves....

i am thinking your going to need the whole works there buddy

hook up with teeitup....randy....

better yet make a post for 350 non a/c pulleys needed on the parts board :flag:

yea what rage said........:D

i guess 6 cyl. are designed alittle different as far as the balancer go, my 6 cyl. balancer has the belt grooves in it?

I would go with new parts...call Sallee Chevrolet and talk to their parts department....800-545-0048. The pulleys you can find from a board member....original small block units should work.

Rage n Rat had a great suggestion with the pulley post but buy a new water pump and make sure your radiator is new or very clean along with your heater core.

You could buy new water pump and crank pulleys as well as alternator brackets at GM dealer if you wanted to. Or, support one of our fine board members by buying them used.

The p/s brackets and pulleys are going to have to be bought used, as they have been discontinued by GM.

The secondary bolt on crankshaft pulley for the power steering is somewhat hard to find. With power steering, there will be two pulleys stacked on top of each other on the crankshaft. I've seen them both cast iron and steel.

The 6 cylinder harmonic balancer is different in that it has the pulley grooves cast right into it. Small block doesn't, it uses bolt on pulleys.

I've done this deal several times, and it can get real tedious. It is much preferred to buy all of the pulleys and brackets as a set from someone.

Personally, I use used parts and bead blast them and coat them with POR15. It gives great results and saves lots of money.

Board member teeitup would be my first contact. He has most everything and is very fair on prices.

On small blocks, I have had good success with Hooker comps and Dynomax headers both. Or, plenty of board members have stock manifolds for sale usually. Day in and out, manifolds will be much less hassle, but, at the expense of a horsepower loss.

The easiest route would be to leave the motor in the I6 position and use a long waterpump and pullies and brackets. They are much easier to find and really a better design. Then you can use the driveshaft you have now and the only real downfall is an HEI is really tight on the firewall....but it will fit. If you want to go with the V-8 position you need the short waterpump and pullies and get a longer driveshaft. To my knowage nothing off the I6 will fit the V-8. I really don't why Chevy made a different position for the 2wd V-8's...the 4x4 V-8 are back there...
