Time to order cam- 400 Engine Project
I'm looking for opinions on a hyd. flat tappet camshaft.
Give me a Part# and some specs.
Thanks in advance

I forget what CR you were aiming for. I have similar pistons with worked over 2V heads and around 9.5 or so to 1. I'm using the smallest hydrolic roller from Crane and would consider bumping it up a step. They offer 4 grinds. I'm extremely happy with the flat torque curve. my specs are something like 218/224 with .560/.580 at .050.

Here's a link to the list of cams I put together for my 400. Specs are Badger flat tops, Cleveland-2V heads pocket ported - no gasket matching, roller rockers with Crane conversion, E-brock 3771 intake w/650 cfm carb, Hooker Supercomp headers.
I ended up going with the Crower piece, p/n 15241, with matching double springs but as of now this engine is still on the stand since my dyno guy moved out of state so I don't know how it's going to perform.

For max low RPM torque use the Comp Cams 255DEH (32-206-3), or for a little more HP use the Comp Cams XE256 (32-241-4). For a little more wind at mid range use Comp Cams 265DEH (32-207-3) or XE262 (32-242-4).
Maybe you should use the Hotrod magazine cam 32-000-5 for more Horse Power, but you should have more compression for that cam.
To really demonstrate the compression and quench, I think that the 255DEH would be the best.

Do you have the specs from the magazine article. 32-000-5 is a Comp Cam generic part number for a custom cam. I will be pushing the compression to the high 9's so I feel I would like just a little more duration.

If possible it would be neat to see the difference between a dual pattern cam vs the older grind of similar specs to see the real world gains with the dual patterns that seem to be the favorite recommendation of many. The Crane #523941 fits in the range of what you are building for. 524/519 lift and 216/228 dur @.050. Recommended for 8.75:1- 10:5 cr. 2000-5000 power band, 2600-3000 cruise .

It is Comp Cams X-treme Energy Part #32-000-5, Grind #FC5433-5216H110
Intake 268 adv., 224@0.050, 0.0524 Lift
Exhaust 268 adv., 230@0.050, 0.530 Lift.
The torque curve is fairly flat out to 4500 RPM, with peak torque of 426 ft-lbs@3500 RPM. The peak HP is 354@5000 RPM. The torque at 2K RPM is a meager 406 Ft-lbs compared to 465 ft-lbs with a 255DEH cam. However the 255DEH cam drops off before 4000 RPM.
The XE268 is a better all-around street cam.

Tim,
Does Chris Samuel still hang out on these boards?
I spent a lot of time on the old mail lists before this website existed. Back around '98 or so. I think that Chris was the guy who had the most experience with performance 400 build-ups. In fact I still have some of his write ups saved that have survived many moves from computer to computer.
I do remember that he preferred an asymmetrical dual pattern cam.
later,
GJ

The Muel is still kickin'. He's never hung out on these boards tho' he was actively involved in the old mailing lists. He's still on some other lists and I still chat with him on an infrequent basis. His employment situation has been rapidly evolving for lack of a better term so he's been moving around the state quite a bit. He did favor a dual pattern cam, in fact on my list of camshafts the one labelled Custom Cam is based on the specs he & I discussed at length.

Hi Bill,
When I was digging back through my archives I found your post from Aug. '99 when you had discovered the existence of the Ohio Piston flat-tops!
Ah, the good ole days! Deacon, Azie, Sleddog, M-Block Dave, Steve D..........it all started to go down hill the day Ken split the old truck list

Don't forget ol' Gary in MI! I don't know if you heard that his wife passed away a couple of years back and he's since dropped out of sight.
Dave is pretty active in this forum, he goes by the nick of BubbaF250. I haven't heard from Deacon or Sleddog for a long time but Azie is still active on another list. Steve D seems to have gone survivalist or something, no one has seen hide nor hair of him for years.
Badger pistons is still making those old Ohio flat tops and the guy who started this thread, Tim Meyer, is who I eventually bought them from for my 400. He's worked a deal with Badger to produce the "custom" flat tops that he's using in this 400 build up. They have a higher compression height than the stock ones so they come up to "zero deck" on a stock 400 block. He sells them on his website.

If you check the specs on most Ford OEM cams they are dual pattern cams. Fords just seem to do better with dual pattern cams.
With compression in the uppern 9's the Comp 255 DEH would not be good. We need the specs on the motor to spec the cam.
