How fast will my 67 be?

Sick467 · 10-04-2009

That's actually a very hard question. I will struggle to keep from just blowin the motor out, but I would love to build my 67 as a driver. I hope to build a 289 or 302 backed with an AOD. I have a set of 3:73 gears for it from an exlporer. Can you all give me an idea of your build with horsepower estimates and some quarter, eighth, and/or 0-60 tiimes. I think I'll end up around 275 to 300 horse. Can you all add your gas milage and rear gear ratios.

Thanks for the chat!

I'll have to let you know in 6mos. or less, my motor hasn't gone back in yet. Are you staying with the stock crank or stroking it? Stock heads or aluminum? Stock cam or ? lift. All of these will have a big affect on guesses.

I'm trying to determine all those things. I would like to stick with the stock bottom end. I have a 65 289 V2 and am not opposed to aftermarket heads, 4 barrel carb, & a beefy cam. BUT, if that's not enough power for my liking, I'll have to ramp up the horses. I would like to balance the upgrades with drivablilty, reliablity, gas milage and longevity. If I can get about a 14 second quarter with a stock bottom end, worked stock heads, heathy cam, 4 barrel 500 to 600cfm carb and a set of headers I'll be very happy (and approach 20mpg on the highway) . That said, if a set of aluminum heads gets me in the 13s - whoo-hoo! I have a GTO that runs mid 14s with a 400, ported stock heads (10.75:1), heathy cam, headers, stock 4 barrel, 400 turbo auto tranny, and a set of highway gears under the back. If my Mustang can compare I will feel at home. With the 3:73 gears and almost 1000 pounds lighter the Mustang should have a chance in competing without over doing the motor.

I'm not really looking for guesses, but rather examples to help me detemine my recipe for a fast and solid drivetrain. I don't want to overbuild/overstress my little 289. Teardown of the motor will start this winter.

Horsepower
230@4800
Torque
310 @2800

That is the stock ratings for a 1968 302 4v which is what I have in my '67.

Faith No More, Tell me what gears and tranny you got and some idea of its speed, Please.

Well, I'm running 3.55's and a C4. i've gotten up to 148.3 MPH but didn't try taking it any faster. I'm putting out somewhere around 250 Horse Power.
