I'm getting rid of my old lg4 and putting in a goodwrench 350, and
I was wondering what my 1/4 times and mph should be. Here
is all the other things being done.

Goodwrench 350 (250 hp)
Edelbrock performer intake
Edelbrock performer carb (600 cfm)
Edelbrock TES 1 5/8" headers
Catco 3" cat
3" Pacesetter super turbo catback exhaust
Switching to dual electric fan setup
Rebuilt 700-R4 with shift kit
Performance distributor, coil, and wires
K&N air filter
Dual snorkel l69 air cleaner assembly

Also I do not have AC, the stock rear is 3.23, and estimated
weight with driver is ~3500-3600 (on the title curb weight is 3062).

I am hoping for mid 14's, but I am not sure if this will get me there.
If you need more info. I will try my best to supply it, and I
am curious about any suggestions of mods to help out. However,
I do plan on swapping the cam (possibly heads too) after the warranty runs out, and
I know there are no problems with the engine.

 

I'll take a stab at it and say high 14's Heads and Cam'll get you where you want to be

 

Does anyone else want to venture a guess . Please .

 

mid 11's
