454 hangin' from a tree
Yes I did, only thing is, I'm goin' to go with the 3gang pulley. That way I shouldn't have any prob with stuff lining up.
I'd still like to getParagon'snumber.
Ya never know. 
Thanks Bro!

I understand the 3-gang theory, I added a single groove pulley to the stock 2-gang years ago on another vehicle, fabricated bushings and used longer grade-8 bolts and ran for many years, anyway here's some more info for your files. Paragon Reproductions, Inc., (800)882-4688, Tech support (810)655-4641, www.corvette-paragon.com, they have an informative catalogue and are a GM authorized resto parts manufacturer. Keep on keepin' on.
O. K., backfrom Summit.

I didn't add state sales taxes, 'cause they all vary.

No more rattle from the piggy bank.
Gonna hav'ta put on the brakes 'til I scrape up some more scratch. [&o]
I'll be postin' Part 2, when the grass is a little greener, so bare with me friends.

Would ya believe, a10 sec truck?
A twin turboed 454 is hidin' under the hood.
Belongs to the guy that built my 454.

Here's a little breakdown of the process so far. 
Ya gotta have something pretty stout ta lift a 454, them babies are real heavy.
They use the same motor mounts as a SB.
In order to get the drive shaft installed, after the engine and tranny are in, I think it's best to disassemble the front yoke. Then reassembleafter the yoke is inserted into the tranny.
Be sure that the oil pan is for a '74 or earlier BB Vette, or you will have a clearance prob with the steering.
Pay close attention to header clearance. The idler arm can be a probas well as the steering box.
Use a short water pump, and a 63/4" crank pulley.
After the piggy bank is replenished, I'll be goin' for a new radiator. A nice thick one made of alluminum.
Carburation and intake are still up in the air, seriously lookin' at dual quads. Carters!Hood clearance? A tasteful scoop will cure that.
Ya, I still have quite a shopping list, but at this stage of the game, I feel that I should do any add on mods. Once she's back on the road, I won't want to take 'er out of service to do anything more.
(for a while
)
If you're goin' to take on this conversion, take your time, and most of all have fun with it. A couple of yatold me that deadlines just cause stress, and boyare ya'll right. [sm=icon_rock.gif]
I'm goin' to step back now and take a deep breath to get ready for the next steps.

Thanks for the update, it has been an interesting project and it's fun to follow your progress. I had dual quads, way back when, you might be better off with one carb you'll find it easier to tune, just my 2 cents worth, PG



We'll see.
