If you don't plan on boost, it might be worth shaving the heads to get the comp up a bit.

$3,500 for a 6L crate engine? That's a bargain. It's more than that in parts alone to rebuild one

We're talking 2009. Bargains everywhere post GFC.

Nah. Just waking her up, not chasing numbers.

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.

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.

shopping list
Cam
Double valve springs
Ls2 chain damper
pushrods
Upgraded lifters(tie bar)
High volume oil pump
skim heads to get comp up a bit.
