I found the short KYBs to be more than short enough for this - they were actually a struggle to get in the beam because they were so short. I bought them because I was struggling to find the almost legendary 90/10s in the UK
Because of a quirk in the way my adjusters were welded in there was almost no travel in my front suspension - the car could be lifted (just!) by one person at the front end and easily by 2 as it was so light, even with a full street weight stock beam and front drum brakes and a 1 gallon cell full of race gas. I found it to be ideal - the car launched well with the front tyres just touching the track. I had a bit too much squat due to stock rear torsion bars though
