Looking for peoples thoughts on these gear ratios for a NA motor but not a high reving motor.
More street than strip
gears (weddle)
3.78
2.36
1.31 (welded)
1.04 (welded)
3.88 ring and pinion
Thank you

I think this will have you more in the high reving range personaly. For street I'd suggest the 2.06 second. and a .89 fourth.

what jason said, but with a 4.12 RP. strongest 'stockish' gearbox and a good cruiser/driver box IMHO.

That sounds like a terrible gearset. Long 1st, close second, huge 2-3 drop, and a final drive that works out a little shorter than a stock 4.12 box. I'd take a stock ratio 4.12 box over that any day.

For that tight second, your 3rd is too tall. Build it that way, you'll experience a bog everytime you hit 3rd.
A better split between that 2nd and that 4th is a 1.50.
I agree with the above. 4.12 is where it's at.

Well he said he was running the 3.88, for 4.12 I suggest
3.78
2.06
1.26
.82 Keeping in mind he's looking for streetable cruising.
