I’m sure you’ve built enough motors to have a pretty good handle on what to use to get it to have the balance of power and drivability you’re looking for.

I did this engine back in 85, just ain't up on the new stuff, reason I'm relying on you guys in the know to point me in the right direction. Believe me, I will listen, I like the details.

The reason I'm asking is I had read before about some cam company who makes a cam for these low comp engines with a radical sound. Can't remember witch one, just looking for feedback if someone had used one and had results. When a race car it would stop pulling at 5000, this same cam in my 383 HC, would go 7000 easy, still pulling. Cam is over 40 years old. Cams should be better now. Cams are a little better now, but mostly they are better with street driving characteristics. The 509 is waay to big for what you want. Its a Great performance cam with a 4200+ vert, but no way would I want it for a primary street car even with a stick with a low comp engine.

A couple questions on the 509 you guys have, what rpm do you shift at and thru the traps, what springs? I've always used the Isky steel rockers and Crane pushrods.
All cam makers say their cams are the greatest and I have always liked the 509 but I'm leaning toward the new technology to see which has better cylinder filling with a reg hydraulic lifter and be better all around. Comp 924, shift 5700, not sure on trap rpm but went 116. 4.56 gears 31" tires, 9' GER converter that was rebuilt locally. I hadn't started the car for several months, tapped the gas twice kit the key, and it fired right up and idled. Timing is 25 at idle and 36 when in.

One of my favorite street/strip 440 cams is the Comp xs282s, which is technically probably slightly on the big side for the OP’s combo......... but would still offer better drivability and vacuum over the 509 cam.

mechanical cam will work better in all aspects. a small to moderate mechanical would be the ticket. I was impressed by a xs274s I rode in several months ago.

The .528/284 MP mechanical that AndyF mentions frequently would be a great selection.
I ran it in a stock ring/bearing 9:1 440 engine with 2500 stall and 3.23 gears. It was an torque monster that got mileage to boot. 14mpg!

I'm buying this one from a guy who contacted me...
"Comp 3bolt cam ..505 intake lift…511exhaust lift intake duration 230 …exhaust duration246 to be installed at 109 intake centerline. Also new Comp lifters (better ones)#867. I had a low pop engine and had Jeff at Modern spec it out."
Sound ok? Hope so.

230/246@.050??
16 extra degrees on the exhaust....... interesting.
I’m sure it will run “fine”, but without dyno testing it against something else..... you won’t know if that’s what the motor really wants or not.
When you get it, post the lobe numbers.
