That must be a 3.31, that is ratio that 12 bolts came with in that range.  That and the 3.55 are the best all around ratios you can get but be forewarned, with a big block you won't be passing many gas stations!

That's good news. I ordered new Delco upper and lower ball joints as well as control arm bushings from Carl Stevenson's dealership (yes, ordering them from him was still cheaper with shipping than from the GM store I worked at located 2 minutes from here-any wonder why I left? furious). I figure I better get the front end up to snuff before the big block swap.

You might have received a slight "adjustment" on the purchase price as a fringe benefit since you are responsible for starting this site wink.gif



Its true if you know some one at a dealer ship you get a good cut. My dad works at a GM dealer ship and I can get delco parts cheaper than jobber quit often

Tonight I removed the alternator and fan pulley. I sandblasted the pulley and alternator brackets .
I cleaned the parts with mineral spirits. The cheapie filter on my compressor doesn't remove all the oil in the air and I get fish eyes if I don't clean them first.

Apr2009033.jpg

After the parts dried I gave them a good coat of high build primer

Apr2009035.jpg

Tomorrow I'll prime the other side of the parts, hang them by a wire and give them a coat of semi gloss black. Exciting eh?biggrin
There's still quite a bit of detailing/cleaning to do before she is ready to drop into the car. There are a few bits and pieces I'll need too.
So far, here are some parts I need:

An early water neck - this engine has fitting screwed into the top of it.

A fuel pump- this one has a big dent

I also wouldn't mind a decent spread bore aluminum intake. This one has a lot of smog fittings and I wouldn't mind both the weight savings and the performance boost. I want to retain the Rochester carb

If anyone has any of these they are willing to part with please PM me with your price.

Thanks
Todd

I have a housing and I think a pump    A few brass fittings, painted orange, will get it running.. It would be nice to get it in, and running in stock "big block" form, and see how it performs. You will be pleased with the "torque"... Try to keep motor closed up, until you decide how much intake, camshaft, and carb, you need..  Changing several things at once, does not always give you a idea of how far your money took you..  Again my 2 cents  Carl

Cool, another guy with picture updates on his project. Love it!

I may have a water neck Todd but time and distance likely are against us.

Oh, and my 2 cents on this would be a new fuel pump only, not used. Any fuel pump that has been used, removed and placed on a shelf for more than a few months should be discarded. The diaphragms seem to hate being dried out and you are looking for trouble installing a used one.

I agree Carl. I'll get one from Carquest. I suppose you are also right Carl about the intake. It would be sooo much easier swapping it on the stand though!

Yeah, the difference you would notice with weight saving of an aluminum manifold would be negligible, it would only start to make a difference performance wise over 4500 rpm, how often are you planning to go there?wink

Well, a bit of a setback. I attempted to install my oil pan and soon realized the oil pickup is too far forward to fit. furious The sump is a fair bit smaller on the B body pan.
Any suggestions as to where I can get the correct pick up tube? Since this one is welded to the pump, will I need a complete oil pump assy? I suppose I could grind the weld and press in the correct sump and reweld it...

Replacing the complete pump assembly is one of the cheapest forms of insurance out there.  Since you have the engine out anyway...

they don't generally come with the pump todd.
pump supplier should be able to get you the one you need.

A word of advice when you put the new pick-up back on the pump tack weld it just between the tube and the pump housing, stops that sucker from falling off or moving cause it is a crude press fit at best.

Yes, the pick up that is on there is tack welded. Dave, you are in the midst of putting a 396 in another Impala, right? Did you have to swap the pan? My 454 is out of a pickup. Maybe I didn't have to swap the pan?

todd, very unlikely the truck pan will clear the center link.



the center link sits just in front of the rear sump.

i'm doing a sm/blk 400 in the impala.

When I put the 454 out of a '91 crew cab into my '70 Parisienne, I thought the pan was going to fit as well. NOPE!! The pan that 69 belair has posted looks right but if I remember correctly, the crew's pan was just a 2 step pan versus the 3 step pan 69 belair has posted.
