I seem to be having not a good time with the combination of a 302 with a np435 and 3.50 rear end. I gotta gas it up just to take off in granny gear...Its got really high gears now since I put the 302 down in it...what type of rearend could I get to make it where i can take off in granny gear without hitting the gas like when i had the 300 in it? Thanks

 

4.10.

The problem is the low HP/Torque ....302

 

So if I get the 4.10 gears it would be better? What can I find that in...would a dana be a choice?

 

Axle code 12 or H9

 

The biggest problem with the 302 is that it does not generate much power until you spin it up. You could put 4.56 gears in the truck but then the highway mileage would be about 4 mpg.

 

Ive got a 302 with a 435 and 3.50 gears and 33" tire in a 4x4. I can start off in 2nd gear with no problems. Maybe your 302 isnt running right.

 

For what it is worth for your knowledge, the smaller the number the gear ratio in the rear end the faster the vehicle would be on top end or at the max RPM of the motor. The larger the number the more torque you will have at the wheels. Typically the 302 is an RPM motor or a top end motor.I have a 302 out of a 95 Mustang in my 76 Ford F100 short bed pickup and to burnout you really have to bring the R's up and Semi drop the clutch to get her to bark. However when I am going down the road if I floor it at around 2000 RPM-just cruzing, it will slowly start to pick up untill it hit about 4,000 and then it really takes off and you can feel her rip. Hope this helps to decide what you are looking for and to understand what type of motor a 302 is, Travis

 

That's why they put Longer stroke engines like the 400 and 460 in these trucks for real work horses.

 

My 302 sure likes the higher RPMs. Ive run it in the mud drags and ended up having to go with an MSD igition so I could have a rev limiter after I watched the tach hit 8000 RPMs.
After rereading the first post I dont get this statement "Its got really high gears now since I put the 302 down in it". What does that mean? The gears dont change when you swap motors.
