(Hope this is an OK place to post this question)
If you're not familiar I have a 59 T-bird Rat/street Rod kind of project. I have a 390 with headers, close ratio 4sp, and a 3.89 open rearend.
I have two sets of 15 inch rear wheels. One set are pie crust cheater slicks from "Towel City tires". The diameter is 28.5, the width is 8 inches. I also have a set of modern 225/65 15 inch that are about 25.5 to 26 inches in diameter. The car seems quite a bit faster with the smaller tires. It accelerates better, and it can spin them pretty easy. It won't spin the 28.5 inch tires, at least without burning a lot of clutch.
Does this sound normal? Or should i say, is this what you would expect? With the headers I should be around 350 HP and well over 427 torque.
I have no experience whatsoever with this kind of thing so thought I would ask you guys.
Maybe "Noncontrol" has an idea being that he has a 390 4 speed?
Here's an album of my car if you want to see the bigger tires.
Thx in advance, Dave J
