1970 GTO Judge

[gtome]

Ok. I ordered a set of 295/30r20's and a set of 255/40r18's. I will try these out and go from there. They are super cheap tires, but I will have them for rollers and to try on it once the car is done. Just hope they aren't dry rotted by then!

[gtome]

I put the tire on the rear end today. This is just a rear i had to make it roll. It's a 10 bolt out of a 65 so it's one inch narrower that what the car would have came with. It does "fit" though. I have the tire on the wheel simulator set to my correct 5.5" backspace.

What size is that?

[gtome]

That's the 305/35r20

What's the specs on the camaro wheels, looks great!

I'm not sure on the camaro wheels. It's not mine. I was just doing some work on it.

[gtome]

Got the rear wheels today. Look ok for $289. Fronts will be here Wednesday.
Also got the new tires. Got 295/30r20 for the rear and 255/40r18 for the front. The 295's are kind of disappointing compared to the 305 I was hoping to use.

[gtome]

Had the tires mounted today. I was kind of pissed because they chaeged me $88 to put 2 new tires on 2 new rims. Then it started to rain as soon as i put them in the truck. Oh well. This weekend I will put the body back on the frame and do a test fit. I know these will fit in the car, but I can measure for the rear end now.

[gtome]

Looks like there is plenty of room for a 305 in there if I decide to go a little bigger in the future. I bought the wrong lug nuts, so I had to put some old ones I had laying around on it. I tried a 70 GTO style lug nut on it, but it's so deep in there you really can't see it. Also rolled the 305/35r20 to put next to the 295/30r20 that is on it, for a comparison. I'm a bit surprised how much taller the 35 is than the 30.

[andrewb70]

The shorter tire will work better.

[gtome]

Grrrr! I could have easily fit those 305's in there. Maybe even a 315. Oh well. Maybe once these are burned off.

[andrewb70]

I told you I use 305/35-18s on my 70 GTO and there is plenty of room if the wheel offset is precise.

[gtome]

Yeah I was unsure with the height difference in a 20". Oh well. I paid $107 each for these 295/30r20's, so it won't hurt much to replace them. I'm a little surprised how well they fit with the 1" narrower 1965 rear in it. Must be the 5.5" backspace.

[gtome]

Pulling the rear out tonight to measure for the 9" ford. I plan to maybe put a cam in the LS3 and not much more than that, so probably just 31 spline and maybe 3:70 gears. I need to get back onto a gear calculator and nail that down.
We do some powdercoating at work, and have a huge oven, so I will do the rear and frame here. Then I can move onto doing the bodywork.

[gtome]

Still grindin. Got all but the hood and nose in final primer.

[gtome]

Trying to keep moving forward during the 3 weeks of winter we have. This wheel has been staring at me for a while. Probably the most disgusting one if ever seen (or felt!). Soaked it in Dawn overnight. It's not great yet but it helped a little.

Darn, Sorry I'm late to the party I could have helped. I ran a 305/35R20 on my 69 Pontiac for a while and only ran into rubbing issues when I had people in the back seat and hit a pothole other than that I never had any fitment issues after rolling the fenders a bit. Project looks great though.

[gtome]

Thanks brother. I am going to have a 9" built for it, so if I get the measurements right on, I will put some bigger ones on the next time. These are super cheap tires I got for it this time too, so who knows how long they will last anyway.

Man I just went for a ride in my buddies new GT500 track something mustang with the dual clutch trans. That trans is awesome! I might have to see what it takes to do a ZF or whatever they are called in behind my LS3. It's a whole different experience!

The ZF8HP is not a dual clutch transmission, but it has very fast shifts. Here is a post that I started on LS1 tech which outlines all of the details:
