Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
That cams a bit old school ls1, get a bigger slit as l98 inlet valves are huge and exhaust small, i had a 224/244 cam in mine was a rev rocket.G'day, I have a replica AC Cobra with a stock (untuned) L98 and T56 with 3.7 rear end (S15 200SX). Tri-Y headers with 1 7/8" primaries into a 2.5" system with X-pipe.
The gearbox is out for a mid shift conversion and I'm going for a tune and maybe a cam.
Looking for a lumpy idle and good even torque curve mainly for street use and the odd track day. The car weighs around 1100kg so it needs good manners.
Top of my list is a VCM480. What supporting mods should I do? Trunion upgrade, double valve springs? Any other suggestions? TIA.
I'm wondering how long ago his purchase was?$3,500 for a 6L crate engine? That's a bargain. It's more than that in parts alone to rebuild one
