I have a 401 with what I beleive to be a stock cam. The motor was rebuilt and has almost no time on it. Still has fresh cross hatch pattern in the cylinder walls. BUt it did sit outside and now I'm just cleaning it up and out real good. And increasing the power a bit while I'm at it.
I want a reliable daily driver that still gets decient MPG's as long as I stay off the throttle. I'm building to get a couple 100,000 miles out of the motor.
I'll be hauling the parts to my mechanic (he builds racecars in his spare time) for his opinion of the condition of the motor tomorrow.
I just pulled the cam out and the bearings appear to be new. The cam even appears to be new. No wear or score patterns. Same for the lifters. No wear or score marks. I see no scoring or wear. So if I want to replace the cam, do I really need to replace the cam bearings? THe FSM says I need to use a line bore with new bearings.
So can I just swap in a Cam?
I am looking for off idle torque.
THis is the plan.........
approx 9.5 pistons,
stock heads cleaned up a bit,
Edlebrock Performer intake,
Doug Thorley Try-Y headders
maybe a Howell EFI or a Truck Avenger carb.
I'll upgrade the oil system a bit and use a TFI ignigion with a CS144 alternator. Everything else basically stock.
I am looking for idle to 5000 RPM. The desktop dyno tell me I'll be at 444 torque @3500
and 335HP @4500 wtih a Comp cam XE256H.
So what suggestions do you guys have?
