Looking for a starting point dimension for setting the wheelie bar of the pavement ? Have a 175" FED with a BBC 33X15X15 Rear tires. Also how many RPMS should we expect to spin during a burn out w/5500 stall. Thank You

Burnout RPM’s is totally dependent on your right foot! They come up quick!
-
Wheelie bar height depends on the length and stiffness of the bar itself, how hard the chassis rotates at the step, how much the car squats into the tires, etc.

Seems like good starting point is a few inches or less mine likes 2 3/4 in higher and she leaves more violent and real high you are on a crazy ride

That's lots of rear tire.
Your wheelie bar setting is very important.
Start low and raise it up a little at a time.
Been there, done that.

We don’t have any info yet on how the car leaves, squat etc... the bar is a single wheel and almost 7 foot . We are newbies formally boat guys. This is all new to us. The car came with the that size tires so we just replaced them with new. We welcome any input that will help us. This was a project that my son and I started with pops who passed away just as we were completing the car. my experience was on water pop raced on asphalt and was our leader. We miss him but I know he wants us to carry on. So we will give it our best. We Thank you for any and all advise

Mine sits between the 3rd and 4th row of lace rivets on a set of chuck Taylor’s. Haven’t adjusted it since. (A lot of my friends use this height) although I have different combo, 31” tire, 3500 stall, 500” motor.

That tire size is going to be tough, we did the 14 x 32 tire for a while and if track prep is good I would start with a very low pressure like 5.5 psi and creep up from there, keep the bar low until you find a happy tire pressure to work with. If you look at ntf they only use a 13" wide tire...
