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.

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.....

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! |

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.

PJ, Don't overlook the chassis. The biggest gains in e.t. i made with my 283 LA Nova was when i aligned the front end, making major adjustments to caster and camber and having the rear end housing straightened and made sure it was perfectly aligned in the car.
