[HWYSTR455]

A little more on the Spotts built IA2 535 :

IA2 gen 2 block, finished with 4.350 bore, deck cooling holes drilled
Eagle Forged crank, 4.50 stroke, 2.20 rod journals
Eagle H rods, 220k bolts
ICON pistons
Crank scraper and windage tray
Canton road race pan
Butler 315cfm E-heads, round port, with minor additional clean up
PAC springs & retainers
Crower Enduro 1.5 rockers
Main & Rod clearances - .0025
Melling Select 80 psi pump, checked/clearance

Cam - Comp Cams solid roller (custom)
Hi-Tech lobes
260/267 @.050, 112, .631 lift

This was originally going behind a manual car with 3.25 gears, so cam is a little smaller than I would have gone for this setup, but still should be fine. The heads are only 315-320cfm, so it will run out of steam with anything bigger and not have been able to take advantage of it.
