Description
Go to youtube under spotperf to see this tray being installed.
see my other auction for crank scraper
Windage tray is designed for the aftermarket IA2 and KRE blocks but works on all Pontiac V-8’s with splayed or regular main caps – both 2 bolt and 4 bolt! I mostly use this on steel 4 bolt main factory blocks. It will bolt on all 3 main caps. The tray also acts like a mini main cap girdle. This tray was used on my 1000 HP blown alky dragster for 10 years. I attribute this windage tray and my crank scraper for never hurting a bearing in that engine.
Tray allows for better oil control and entry back to the oil pan then glue on trays.
Controls windage from higher RPM engines.
Tig welded stands are super strong.
Will not crack or break like factory style trays with redirect curve. Tray is designed as a quick install/removal for engine builders and checking bearings where time is an important factor. A crank scraper is recommended with this tray. Dip stick tube (if used) must be welded or staked to external tube – or a bracket must be welded and bolted to tray.
I recomend the Canton oil pan with external dip stick – or no dip stick at all.
Windage tray may need to be shimmed to clear certain stroke/rod combinations. Shims should be made from rectangular stock – washers not recommended. Shimming more then 1/4″ may not allow the oil pan to fit. I never needed to shim the tray much even for 4.5″ stroke cranks.
Rotate crankshaft several times and check for clearance.
It may be necessary to straighten louvers to clear connecting rods.
Tray may need to clearanced by bending for certain oil pumps. It is best to fit all components. Tray may be mounted with allen socket bolts, or pan head bolts. Regular 5/16 bolts with 1/2 hex head will not allow socket to fit. Chrysler header bolts with a 7/16 bolt head will work. You may also use 5/16 carb studs and 12 point nuts from ARP. Grade 8 lock washers are also recommended.
Developed by Spotts Performance when I tested the very first IA block for All Pontiac.
