Re: 2.56 Gear, Stock Converter, 4100 Pounds, NA 11s?

Very very cool! Have you tested your 60 foot &/or 0 to 60 on the street with your Dragy? Mind sharing? I tried one time before rebuilding the suspension and boxing the rear arms, but I haven’t tried since. Not representative of what it could do now. 1/8 mile was 2.35, 8.65 @ 88.47. I won’t run out ...

Re: 2.56 Gear, Stock Converter, 4100 Pounds, NA 11s?

First run was at 11:30 AM, last run at 12:30 PM. The Draggy gives the DA in the screenshot. Only the last pass was flatfooted. Very very cool!

Re: 2.56 Gear, Stock Converter, 4100 Pounds, NA 11s?

An interesting point of comparison, despite the higher MPH per distance at the top end, at no point while Al was racing was Mike reeling him in. From Mike's point of view Al was *always* pulling away. Doesn't mean anything, it would be just interesting to see the track length required for them to b...

I created the graphs from the simpler data, not foot by foot. thanks for the correction ! and what Software are you using to create your Graphs ?? Excel or...

Take a 1970 Monte Carlo on street radial tires, bone stock survivor with a 2.56 gear, Turbo 350 with the factory stock GM TQ converter, add a 496 with 9.8 compression with a 228 @ .050 hyd roller and GM 049 heads-will it run 11s?

Re: Peanut vs Oval port, velocity, etc.

very cool. now i wanna see how fast i can go in 4x4 with a 496, th350, np205, and 32” duratracs ... Sounds like a cool experiment. Build for torque, follow Mark’s videos. If you want to buy heads, AFR 265. These are the highlights from the last year. https://www.firstgenmc.com/forums/index.php?/top...
