Tell me about your cam specs

[runamuk]

I'm finishing up my engine and still shopping for a cam.

My engine is a 428 that is a World products Man-O-War block based on a 351W bored to 4.125 and has a 4.0 inch stroke. The heads are AFR Renegade 20 degree heads with 220CC intake runners. I'm using EFI from Speedmaster throttle body system with a FAST EZ-EFI 2.0 controller. I'm leaning towards a Howards cam with 110 degree lobe separation, 219 degree duration @ .050 and .544 lift lift both intake and exhaust.

Tell me what you have and what changes you would make if any?

You don't say what your goals for the engine are so it may fit what you are looking for but that is a mild cam for a 428.

Can't help on cam specs for that engine, but I can tell you the EZ-EFI-2 won't work with an EFI throttle body system. Up grade to the Sportsman EFI. Save yourself a lot of grieve and money trying to get it to run properly.

Call the cam manufacturer and discuss your engine, trans, car, and how you plan to use it. The cam manufacturer will recommend a cam. They do this many times a day, every day. They're the experts and you won't find that kind of help on any forum.

That seems like a really small cam for a 427, but it would probably drive great around town. I second the suggestion to talk to the cam manufacturer you want to use to get a recommendation.

Amen, regarding calling a Cam Manufacturer.
While we all know the basics, most of us are far from being experts.

If there was one person here I'd trust to give a cam spec recommendation, it would be NAZ. If he's saying to call the manufacturer... well, there you go.

I reached out to Iskendarian Cams for my 351W using the Fitech system. The cam they recommended and ground works perfectly. I can post a pic of the cam card if needed. Has a great lope to it and pulls hard all over the RPM range.

Here's my setup for comparison/info purposes. I'm not sure how this cam would work with stacked EFI, probably not enough LSA?

The block is a 1974 Windsor out of a Galaxie bored .060 (the block was sonic checked and had plenty of beef left so we reused it) adding a 4.00" stroker crank made it 414 CID vs a normal 408 @ 4.030. The rotating assembly is all Eagle 4340 forged steel with their H-beam rods, Clevite H-series bearings, ARP stud kit, KB 10:1 pistons, plasma moly rings, and an ATI balancer. The heads & intake are ported Edelbrock Performer RPM with the bigger 2.02 valves and comp 370 lb/in springs. Carb is a Quickfuel SS-650 (it's a bit small but hasn't been an issue). Cam is a Comp XR282HR roller (230/236 @ .050, .513/.526 Lift, 110 LSA) with Ultra Pro Magnum 1.6, 7/16" rockers. The motor made 485 hp and 520 ft/lb on a Superflow dyno through mufflers in 2013.

Drives great, sounds great. If I had to do it over again I probably would have gone with an aftermarket block and 4.125 bore. Good luck with your cam selection. It's a major decision. Scott

Thank you I'll check them out.

To everyone else, I have called both Howards cams and Comp cams. You wind up on hold forever, I have submitted all of my build specs to both companies and I'm still waiting to hear from them. As for Comp cams I submitted my specs two weeks ago with no word yet and I have zero plans to spend hours on hold.

My hope was to hear from someone on this forum who built their own motor.

Very cool, this is exactly what I was looking for, thank you

You're engine is very similar with the exception of the carburetor. I wound up going with a Howards Cam CL220325-10 which has 225/233 degrees duration @ .050 lift and .560/.565 lift on a 110 LSA. I'm also using 1.72 roller rockers which will give me a little more lift.

Here are the cam specs for my 383 SBC which may give you a reference point for your 427 SBF camshaft selection.

Just know that fuel injection systems seem to run better with a larger lobe separation angle of 112-113.
