With the relatively small cam and the Performer intake manifold my guess would be about 350hp at 5000 rpm. It should have plenty of low end grunt thought, which is the goal with this one.
To clear 400 hp you need a bigger cam and better intake and bigger carb.
Page 3 shows dyno results for a 9.5 compression ratio 401 with a Isky 280HL cam, Torker intake and 750 Holley which made 380hp at 5200 rpm.

If you want your peak horsepower at 6250 just go with a bigger cam, Torker intake and bigger carb.

600/650 cfm. I wouldn't go much bigger unless you change to a Air Gap or Torker intake manifold.

Spent 3 hours on the block tonight getting the threads chased and the outside of the block cleaned with one coat of primer and one coat of paint. Now I can clean the inside and start the assembly process.
Bare Block

Zinc Primer

Base coat of paint

Progress: I got the short block assembled last night. Nice shinny parts!



The timing gear wasn't too bad. Didn't have to move the slot over much to line up with the can oil hole.

No, it is just a base coat of Torque"N"Teal. I will spray a couple of coats of AMC Blue after I get it put together.

Worked on the Timing Cover and Oil Pump Cover last night. The timing cover had water in it at one time so I carefully got the corrosion cleaned out and lapped the gasket surface.

I ran a tap through all of the threaded holes to make sure that everything goes together well.

Oil Pump Cover: Started with 80 grit wrapped around a file and spent about 10 min to get it to this level.


Spent another 10 min with 150 grit and got it to this level.

Spent another 5 min with 320 and got it to this level. At this point, it is probably as good as the factory finish. Up until now I sand in a cross-hatch motion. The key is to keep it as flat as possible.


Finally with the use of WD40 or Liquid Wrench, I wet-lap the surface with 400 or 500 grit sandpaper. I lap it in a circular motion.

Beautiful work.
I'd ask how much one of your 401's costs, but you know the saying, if I have to ask...
I appreciate the craftsmanship you are putting into this. Thanks for sharing!

This is not my full time job so, it's cheaper than you think! That is why I am always busy.

Thanks! I try..
1/4"-20 x 3/8" nut and bolt to replace the plastic button that the factory puts on. I use Loctite on the threads.


I make sure I have all the right bolts for the water pump and timing cover before I bolt things together. This is where I find out that I am out of 1/4" lockwashers and have to make a trip to town..
I make sure that the water pump impeller doesn't scrub the timing cover without a gasket in place. I install the water pump to the cover first then, the cover to the block.

With the timing cover in place and the gasket trimmed where it meets the block it is time to install the oil pick up screen.

I spin the pick up screen on until it is tight and it will clear the oil pan with no gasket in place.

That water pump impeller rub is a real buzzkill. Pretty common as well, it has gotten me once. Now I check before everytime like you!
