YoungMonte Posted April 14, 2021 Share Posted April 14, 2021 Those rims and tire combo looks SIC!!!! What backspacing did you go with so they didn't rub? Quote Link to comment Share on other sites More sharing options...

Quote The fronts are 18x9 with 5.5" of backspace. The tire is a Bridgestone Potenza S04 (UTQG 280) 255/40/18. This is an inch wider wheel than I was running before. The rears are 19x10 with 5.5" of backspace. Tire size is 285/35/19, which is an inch larger in diameter than my previous setup. I increased the diameter for tire selection and aesthetic reasons.

quarterbooty Posted May 19, 2021 Author Share Posted May 19, 2021 Thanks for replying. It's been awhile since I've dropped in and even longer since I've made an update. The car has been through a number of significant changes to the car since the last update. I had a cracked sleeve in the factory LS7 block and ended up redoing most of the engine. The short block was replaced with an ERL dry-sleeved LS2 block with a Callies crank and rods and Wiseco pistons. Heads are PRC LS7 265s with titanium intake valves and solid stainless steel exhaust valves. The compression ratio increased to 11.5:1, and displacement remains 427 ci. The intake was changed to a FAST LSXr 102. Quote Link to comment Share on other sites More sharing options...
quarterbooty Posted May 19, 2021 Author Share Posted May 19, 2021 Last fall I incorporated two C6 fan modules for PMW control. Fan speed is coolant temperature dependent and AC discharge pressure dependent. This spring I swapped the factory gauge cluster for a set of Dakota Digital RTX gauges. I wanted to keep a factory appearance and finally get rid of the column mounted tach setup. The gauges integrate nicely with the Holley ECU without any new sending units. I mounted the control modules under the dash pad on top of the glovebox. Test ride before putting everything back together: Quote Link to comment Share on other sites More sharing options...

sbarnette Posted May 19, 2021 Share Posted May 19, 2021 Nice! I really like the factory appearance of the gages. Quote Link to comment Share on other sites More sharing options...
Energizerlehman61 Posted July 15, 2022 Share Posted July 15, 2022 Fantastic looking car! Question, with that rear tire and wheel combo did you have to mini tub? Quote Link to comment Share on other sites More sharing options...
quarterbooty Posted July 16, 2022 Author Share Posted July 16, 2022 Thanks. No mini tub. This is probably as big of a tire that you can run without trimming/rolling the wheel opening lip or mini tubbing it. Quote Link to comment Share on other sites More sharing options...
Energizerlehman61 Posted July 16, 2022 Share Posted July 16, 2022 Okay, but you did have to relocate shock brackets and remove spring cups correct? I'm getting ready to put coil overs on my 72 and convert to disk. Any input would be highly appreciated! Thanks 👍 Quote Link to comment Share on other sites More sharing options...
quarterbooty Posted July 18, 2022 Author Share Posted July 18, 2022 The DSE coil over bracket ties into the existing shock mount; the mount is not modified. I believe many of the aftermarket coil over setups are similar. The coil spring perches don’t have to be removed unless you want to clean things up.
