Strange as it may seem, I have a real classic mini question. I'm about to have rebuilt a 1098 motor. Is it worth the cost of boring it out, say, 20 thou oversize? I assume theoretically you would gain torque and low rev power which, for a road car, seems to be what is needed. What sort of gain do you get? Is there any disadvantage in going 40 thou? Also, I have almost decided on a 1 1/2" SU with rich needle, improved flow head with maybe 9.5:1 compression, 3-into-1 extractors and an RC40 exhaust. Any comments?
