Built 440 Opinions

[am3rican]

I have a 69 C-Body block that was built about 4-5K miles ago by P/O in 2002. Currently running 6-pack carbs. Goal is reliable power. This is a cruiser build for occassional track.

I need your opinions on the build. Pros, cons, and any other feedback are all welcome. I'm particularly concerned about reliability and maintenance reqs. This is my first classic so just looking for info. I included receipt on build. Stock heads (at least fairly sure running stock heads)

Here are some of the part #s decoded. Machine work done too.
Sealed Power E424K Rings
Sealed Power Camshaft Bearings 1453M
Sealed Power 4924M Crankshaft Main bearing
Speed Pro Forged alum Pistons L2266F
SA Gear Double Roller 250 78104
CROWER Stage 3 32918 HYDRAULIC FLAT TAPPET CAMSHAFT - .444 Int (1.5R), .467 Ex (1.5R) Lift,
Crower 66032 roller lifters
ARP Rod Bolts

You sure about this???
Flat tappet camshaft with roller lifters?
The lift is very low IMHO......... The mild MP camshaft with .484" Hyd Flat tappet has a bit more butt than the one your showing... A 440 with decent compression will EASILY handle more camshaft and wont kill the valve train....

Good luck with your build!!!

No that cant be...I know the cam is right for sure. I must have copied the wrong description on the lifters. Wasn't thinking. I was having a hard time getting a descriptin on those lifters because Crower doesnt make any with those part #s any more.

Roller lifters with a roller cam. Same with hyd and solid lifters. I have seen guys run a solid lifter on a hyd cam, setting the valve lash at .005 or -006". A roller cam usually has a higher lift than .467". Unless its a factory cam in a small block. Which yours isn't. If those ARE roller lifters, and the cam is a hyd flat tappet cam, then you have a mis match. Call Crower if the're still around, or check with Comp Cams tech line.

I called Crower. They are hydraulic lifters for flat tappet cams

It should be reliable with little maintenance required, except for the six-pack.

Power? Eh..........How does it feel to you? That's all that matters.

I like seat of the pants power...

Look on the cyl head intake runner for the last 3 numbers of the head casting number. They are prob 906 heads. (68 to 70, 383 and 440 magnum). You will need to pull a valve cover for this check. Cyl heads are key to good power production.

Chirps the tires in every gear. It's in the 11s on the track too.

The 32241 cam sounds like a winner to me for a street car. The cam you have now is also good and if it's runs well then stay with it. The 2266F pistons I believe are just factory replacement types with a 1.990" compression height and with an open chamber head that's not a lot of compression. Enough for your mild cam and pump gas. Look up my 440 build in the 12 sec forum and you will see it's similar.
