What is the best bang for my buck?

[pjfouts]

Hey all,

I have a 66 Chevelle Malibu with a 283 SBC, powerglide, and 12 bolt. I’m trying to decide what makes the most sense to upgrade to go faster. I’m
Not trying to set the world on fire, just trying to pick up 2 tenths or so. Below is what I have that I know of and wanted to get some thoughts here from people who have seen increased speed in their combos.

I went 11.80 this past weekend for reference at 800’ but 15mph head wind

Engine
283 SBC
520 cast number heads (brand new not sure who machined them)
Scorpion rocker arms 1.6/1.7
Comp cam push rods 8.000 .080
Bullet cam
Crower lifters
Dart block

Carb
4GC completely redone by DeanO

Transmission
Power glide
2.18 low gear
A1 7” converter

Rear end
12 bolt
5.86 gear (I think!)

Other items
Drum brakes
#3465 with me in it

I’d attack weight, chiefly the brakes. TBM brakes can take weight off and decrease rolling resistance.

That’s an easy one, swap the glide for a 3 speed …that will get you your first TENTH….

M.J. is correct. A 200 Metric.


If this is a stocker, I didn't know high ratio rockers were legal.....


Not knowing who did what to the heads, it's hard to say what potential is there.....

[pjfouts]

I should have prefaced. This is a SS/NA car.

I’ve heard 3 speed which was an obvious choice in my head however I’m not sure which direction of 3 speed to go these days. I had a pro trans in my sunfire and that was fast but it needed replacement parts every 30-40 runs it felt like. I’d love to get a turbo350 with a trans brake that would be sturdy enough for when I move classes next year into FGT.

Thanks for all the insight CR!

[Alan Roehrich]

Whether or not you need a 350 depends on what you intend to do later. Usually, a foot brake is faster than a trans brake. And the three speed trans brakes don't work as well as a PowerGlide brake.


Since you're talking about Super Stock, it makes a big difference who did the heads.

Best BANG for the buck is a SS Hemi! When they go BOOM they make a big BANG! Lol

PJ I use a 200 metric by Thomas Arnett and a ATI converter. The 3 speed would be a 10th or more faster. It has been reliable since I figured the issue I had last year.
