This was 410" engine I built for my daily driver '85 Dodge Ram couple years ago. Was real nice working motor...

4" Cast SCAT crank
Eagle H beams
Diamond Dish pistons
Comp 231/237 @ .050" XE Hydraulic flat tappet
Ported Edelbrocks
RPM air gap

I drove it every day of over a year, ~7000 miles 87 octane. Sold it to board member in North East who put it in a 'Cuda & runs 11.80's

Never dynoed this one....
