"MINIMUM 90 INCHES,UNLESS CAR HAS ORIGINAL ENGINE IN ORIGINAL LOCATION AND IS SHORTER THAN ORIGINAL,OR NOTED IN CLASS REQUIERMENTS."
"SO AS IT READS ANY ONE WHO RACES HIS TR7 WITH A DIFFERNT ENGINE FROM ORINIGAL CANNOT RACE AT A NHRA CERT. TRACK. IF YOU DO HOPE THEY DONT CHECK WHEEL BASE AND FIND OUT THAT IT IS 5 INCHES TO SHORT. SO GOOD LUCK . THE NHRA TECH # IS626-914-4761."
Here is the issue with the rule as I interpret it at first glance; what is the definition of “original†is this based on the manufacturer of the automobile and as manufactured? Sounds like a TR8 with and original engine a rover V8 in the original location is not an issue and not shorter than 85-inches “original†wheelbase unless it is overridden in the class requirements to be more than 85-inches as a minimum than your good. Sounds like you need to find a TR8 donor and use your body shell.
Point to carry with you is a much more nasty and beastly car raced in numerous NHRA classes back in the 1960ies.....it had a small block 289 ci Ford V8, 83.5-inch wheel base, around 2,000lbs stock and was known as a TVR Griffith.
