How do these mods sound??
Hey Guys,
New to forum but loving my new vette!!!
I recently bought couple of boxes of summit parts and will be installing in a week when I get home from being out at sea. I'm trying to build some low end torque and only moderate HP as the newly rebuilt to stock specs. T350 will probobly only handle 300-350 HP.
I have--
Summit Stage 1 Intake (with hardware)
Holley 670 CFM Street Avenger
Pertronix Flame Thrower 4 pin module
Pertronix Coil
MSD Super conductor 8.5 Wires
Bosh Plat+ Plugs
Summit Seethrough red cap and Rotor
Summit Aluminum Fanshroud and Electric 2300 CFM Puller
Flex-a-lite Fan controls
Also I will be pulling the oil pan to replace the rear main seal, pan gasket, and front crank seal on the timing cover. I will also be pulling the valve covers to replace the gaskets on them as well. Leaks are a pain...
So what you all think???

I think you will need more than 2300CFM to cool your motor. The stock clutch fan pulls 4000+ CFM.
Look into the Lincoln Mark VIII/Taurus fan if you want to run an electric fan.
I dont know much about that intake, but you can generally find nice used edelbrocks or wieands on ebay or something

I do have a slight concern about the fan, but I have yet to see a CFM number on the MK III or taurus fans, and remember one member saying that those fans were basically just 2500 cfm fans that pulled a lot of amps. I will be trying it out, see if the sealed full shroud makes a difference as opposed to the open setup that most guys running MKIII and Taurus fan have.
As for the intake it is just summit's version of the edelbrock stage 1, low rise

What are you starting with? Looks like a 79. L48 or L82? What do you want to end up with? While you've got the valve covers off, might aswell install some 1.6 roller tipped rockers. They don't cost much and fit under the stock valve covers. Openning up the exhaust will help a lot, headers and duels if you can legally do that where you are.

The rockers and exhaust are actually the next planned upgrade after these mods, funny you should say. I already have true dual exhaust without cats, the pipes just need to be bigger and I need headers to make it all flow better. You really do get the idea I am going for though, low end torque and no big changes like heads just cause of the 3 speed tranny and all. Starting out with a 79 with l48 and just looking to end up with a bit more seat of the pants effect.

Put a shift kit and an external trans cooler on and that t350 will handle some power.
I would personally not buy the Avenger carb and keep the Qjet. Spend the money on a set of headers instead.
With the mods you're planning, I don't think you'll get the seat of the pants feel you're looking for. (not trying to negative, just honest)
The only way to make power with these low compression motors is a head and cam change. IMO
I'm currently doing some upgrades on my wifes Vette also.
58 cc Cumbustion chamber heads, 327 350h.p. grind cam, stock Qjet, Edelbrock Performer intake and 1800 stall converter. T350 with a shift kit and external trans cooler. It's not going to set the world on fire, but should be a little more fun to drive.
