Untouched, Srp forged flat tops, about .002" down in the hole. There was a lot of clearance on the exhaust and inlet valves when I degreed the cam. I can't remember how much, but there was more than I thought that there would be. Cheers.
Cheers Mark. They're a 1-3/4" primary pipe tuned length header with 3" merge style collectors. The start of the collector necks down to 2-3/4" and ends up at 3". They're 'Pacemaker' brand from here in OZ. Cheers, Steve.
G'day Eric, no real idea what it cost 10 years ago to build. I bought bits and pieces, some new and some 2nd hand over a stretch of time, but I'd have said around 10k AUD at the time. No idea of the mpg either, it was never built for anything other than fun. 4 speed gearboxes and turning 3250 rpm on the highway will never give optimum economy either, having said that, it runs nice at 14.5 to 1 A/F on the highway and doesn't seem excessively heavy on fuel either. Cheers.
G'day Wyatt. Cam specs are 240 @ .050" and .590" lift. Never been on a dyno but it certainly Honks pretty hard! Car is still off the road at the moment, missing it a bit. Cheers.
