Improving 1/4 mile times

I have a basic 350 in a 70nova, it has edelbrock rpm heads, edelbrock performer epc manifold, hooker 1 5/8 headers, a holley 750dp, a comp magnum cam .480 lift 230 @.050 duration, 1.5 pro comp roller rockers, for the trans it is a turbo 350 with shift kit and has a 2400 stall converter in it, rear end is a 10 bolt with 3.42 gear, just last week I went to the track and I got a 13.66 at 101.97 miles an hour timing was set at 34 degrees total timing. I was just thinking of going from power steering to manual, and from mechanical fan and water pump to electric, just wanted to know everyones opinion as far as realiabilty is concerned.

Headers must be just Comp not Super comp...? 1 3/4" would be better... The 750 DP a little large a 650 DP would most likely work better off the line for sure... Cam is way small for the heads (around a .525 lift 235-240 duration) of course more stall 2800-3200 with a 3.73 gear...

But the main thing for now looks like the carb being to big...? What are the 60ft times...?

The 34 degrees timing sounds low to me. Typically we run race engine at 38 to 40 degrees (even one engine liked 41 degrees best).

Be very carefull! Don't go too far - listen for ping or watch your plugs

BTW - Cool Car - I have a '72 (Below)

As far as my 60ft times are concerned I did not do very good I had a 2.2 60ft. I was hoping to get it to a 2.0 60ft. I am probably going to stick with the 750dp because I just got it about 3 months ago, however I was considering going from 3.42 to 3.73. What my goal was to reach a 13.3 in the quarter mile so I can have a good advantage over my friends souped up wrx which runs mid to high 13s.

Might try a 3000 stall before you swap gearsets...? Cheaper and much easier to install... It will bring the RPM up into the torque band which is allowing the cam to work better for its RPM range...

get a different set of gears, 3.73's or 4.11's , and a higher stall convertor, i say keep the carb, you might want to put a bigger engine it it sometime, just put smaller jets in it, also play around with the timing, just messing with the timing, you should definitely be able to smoke a wrx, and you will have tons less $$$ in yours, and yours will also sound much better, i don't like the fart car noise

The more gear he puts in the less stall he is going to need to get into his powerband quickly. Dont over-do it.

I like the bigger stahl to.
I dont like the 3.42 gears though. You need at least 3.73's, but 4.10 would be even better.
That low 60ft time could be tire spin to. You running slicks? HG
