L36 block (full rebuild - ~$800 for shortblock)
Cometic 4-layer headgaskets (.052") - brings compression up slightly, maybe 9.6:1 or so ($180)
Ported heads, stock valves (gasket matched and smoothed basically) ($0, just labour)
Overkill BBC cam (218/234, 117 lsa, .528/.507 lift) (~$600 installed, still was a deal)
Fullsize intercooler with reservior (~$800+), Ford lightning IC pump($125), aluminum rad($80), fan on rad ($60)
Ported Gen3 M90 with Northstar TB ($300), cruise still installed/working
2.6" MPS ($100) pulley installed, zero knock with 94 octane, ~14 psi (needs new belt to cure slipping, doing that soon)
Overkill Gen2 FWI ($100)
Pacesetter headers ($350), flange for 3" cutout on DP ($100), manual bolt-on cutout (could install electric, had one previously)
Full 3" exhaust ($500), shimmy 3" in/out muffler ($150), no resonator, NO drone!

People do run stupidly small pulleys. But that cam is not meant for an M90.
