350 build

[screamin86]

pretty much same specs you will like it!

[1980c10]

Update;
short block assembled, painted cast iron gray, timing chain and cover installed, intake gasket, headers, clutch, water pump, fuel pump are now here.
I need to get the valve covers sanded and polished.
-I also would like to buy a new distributor, i am looking for a complete unit with cap and coil cover, non computer and with vacuum adv. anyone know a good source???
-Also looking for some good universal plug wire with 90 degree plug caps
(going to run them below the headers)
I hope to dyno this engine in the next week or two.
hoping to get this thing dialed in just right with the right jet and adv spring etc.
I will post back the results here. any guesses?

[1980c10]

Anybody try ebay distributors? results? Recommendations?
How about this one?

I'm a little leery of skip white. I need to switch out fuel pumps and throw the pro-comp I got from him in the trash. You can go to summit too.

They don't come with plug wires however. They sell a combo kit too but I bet it's over the valve cover style. If you're getting long tube headers, the MSD wires for corvette with headers won't be long enough to go under headers. At least they didn't on mine.

[1980c10]

I like the one from summit.
The parts stores around here get about 140 for a complete accel or msd distributor and thats with a red or blue cap(I want a black cap since I want to hide the wires)
So I would have to spend a little more to get it the way I want.

I wasn't looking for a combo kit. I just happened to like those wires. summit has the same wires for $99 so it's kind of like getting a free distributor. with that deal.

As far as the wires go; I will most likely get a universal set as they will have long enough wires.

btw: I have these headers

I ended up getting a proform distributor and a set of msd streetfire universal with 90 degree plugs. I will run this on the dyno next week

[screamin86]

I'm kinda curious on the numbers it will make.

Nice!

[screamin86]

Wow those are some great numbers! Congrats!

[Grim 82]

That's awesome man

[1980c10]

the quadrajet had major problems.
ran a 770 cfm holley from the dyno shop and a 670-both worked great, needed bigger jets in the 670 to run the same numbers as the 770.
I kept the 670 for better throttle response since both run the same.
I will deal with the q-jet carb guy tomorow, couldn't even hold 2000 rpm to break the cam in.
He supposedly run this on his test engine.
otherwise the engine ran perfect, no leaks, no noise perfect 62-70 oil psi through the rpm range.
I can probably run this engine on 87 octane as it is only 31 degrees advanced.
The 1" open spacer added 8-9 hp this worked becuase it evened out the a/f mixture left to right.
Dyno guy and engine builder were both impressed with the vortech heads and agree'd that these were probably good for 30 hp.

This is the new carb:

Awesome!  Aren't you glad you went with the vortec heads?   Now the trick will be getting the engine running in the truck with minimal power loss (exhaust, accessories, underhood heat, transmission, rotating mass, etc.).

Some interesting reading on the subject:

Shame about the Q-jet.  There is no good reason why a properly rebuilt/calibrated Q-jet can't run as good as or better than that 670 Holley.
