The 70 and 71 use the same grill. The 72 has larger openings and is silver colored rather than black. The 71 has high back seats while the 70 does not, but no longer a factor. I've run my car as both years, currently as 70 with 360 hp. I think the 71 flat top motor at 315 may be slightly better. I've always run a 4 speed at altitude tracks but am certainly not as fast as Andrew.
