Hi guys, I have a 69 road runner with a new 496 stroker setup, auto, 2800 stall converter, running 275/60/15 Drag Radials and thinking about what kinda times I can run at the track. Not sure what gears to toss in, 3:55, 3:91, 4:10? I'm running a cam with about 550" lift and 285 duration, eddy aluminum heads, 1 7/8" headers and an eddy 800cfm for now. Looking to hear your similar based combos, with or without NOS, gears, specificly about and 1/4 times and mph. Thanks for your input

Get a holley 850DP that eddy 800 won't be enough and you'll fade at 3/4 track, and 3.91 at least. What drag radials? if you tune is on and you run 3.91's you'll blow BFG's apart...Hoosier or ET street radials and you'll be ok. When you get it all sorted out it should run 11.80's or so maybe better.

you can thank that weak carb for that. Put a DP on it and you'll be into the 11's easy.

Yeah, I was also using an elec pump, pulling fuel through the 5/16 fuel line through the stock pickup screen that was most likely never seen after car was built in 68. That car's(should of kept it) gone now anyways.
5/16 line is ok. Seen cars run low 11's w/ it, now a dirty sock 'aint gonna help.

I pulled a 1.80 60ft. with those street 275/60 BFG's and only SS springs.
with your set-up a good pair of DOT's would get you way into the 11's. I pulled 1.68 w/ ET streets on a 12.90 car. 1.80 is good for a mid 13 second car

It's hard to judge what is a good or bad 60ft. for an E.T. I've seen shitty 60ft.'s end with fantastic E.T.'s I've also seen great 60ft.'s turn into turds at the other end. Some cars consistantly run bad 60ft's and run better than cars with good 60ft.'s. My real point is you don't always need to shove a monster tire in back to run good, even with basic combinations.
ture and since you have a 4 speed I'm not sure what you were dropping the hammer at.
