1/4 Mile Estimate

Looking for opinions/advice. I’ll post my cars specs/setup.

66 Barracuda, full interior, all original sheetmetal.

3.73 gears in an 8-3/4 rearend with Inward leaf spring kit

Full welded in frame connectors

904 trans, built by COPE, but A&A manual valve body

4 wheel power disc setup

340, but stroked/bored to 416. Forged crank, forged h-beam rods, forged Mahle pistons, hydraulic roller cam, Victor 340, Holley Super Sniper setup.

Cam is relatively mild, .578 lift, 230ish at .050. Total duration is 288/280

462hp on dyno

I am installing a Nitrous Express 2-stage setup and will probably start with a 100hp shot on both stages.

I’m afraid my car will not meet track requirements due to potential 1/4 time…no cage

I’m new at this and have no idea what this setup could run. Any help would be appreciated.

17” billet specialties rims…

front MT runners 26x6
Rears are 245/45 drag radials

No line lock setup
Richmond gear calculator ( the most Optimistic)
Say 462hp with 3,000lbs could run a best of 10.47@125.5mph

Drag Performance Calculator

Wallace racing gave a more conservative.
10.87@124.37mph

ET-MPH-HP Calculator

With small drag radials, I am thinking that it will be tough hooking up. I would be happy with 12.0s and expect your mph to be alittle over 120mph.

ET is all about the launch/traction. More often than not the mph is pretty close if you have decent traction.
