SB Stroker - What Cooling System?

IR temp gun is around $30 at Harbor Freight.

IIRC, your radiator opening is only 22"

38 degrees of timing seems a lot for a 4" stroker motor. What is your cam specs and compression?

I'm running a comp XE274 cam, 9.7:1, quench, and 31 degrees of timing. 4 core champion, home made shroud, 15" 7 blade fan, jag fan clutch.

Sorry autoxcuda...I overlooked these questions.

Comp XE285HL, 10.1:1 SCR, 63cc Edelbrocks, .039 Felpro 1008's, 20cc dish Wiseco Pro True pistons .007 down.
26" 3 row OE style brass radiator with factory shroud.
Still playing with initial and final before I set the slots.
'215' 7 blade a body clutch fan and thermostatic clutch from a 90's Diplomat that is still nice and tight.
Yes the opening is 22" but in my opinion not worth cutting.
