Looks awesome. I'm a huge fan of Steve stropes designs at pure vision! Wheel spin is always an issue. I built a 360 ci duster for a good friend with twin T04s stock ported heads and 9.5 to 1 compression. It has a 904 backed by a 8 3/4 2.94 gear set with a spool. That car runs 10 ohs at 140mph. He runs a 275/60R15 street tire for freeway cruising. It will annihilate the tires at anything under a hundred. And I when I say annihilate I mean it goes straight for the rev limiter. Just be careful is my point. I think I'm a pretty experienced driver and it scares me haha. Oh and it came real close 200mph on the dyno when we were setting it up!
