Another “what cam” thread... #2650055 04/28/19 10:55 PM 04/28/19 10:55 PM

It is a ‘65 426 block, stock .010 crank and rods, TRW 11:1 pistons, 452 heads with a valve job and light port cleanup. Crane gold rockers. Obviously it has a A&A repo crossram and max wedge exhaust manifolds. Being a small block and aftermarket head guy, I’m used to larger lift cams... what would be a good cam for this 426? It’s a street cruiser, so he’s mainly after that ‘60s race sound and drivablity more than actual performance. It’s going in a ‘62 Dart with a 3000 converter and 3.55 or 3.91 gears. Thanks

If so you will probably have detonation problems on todays pump swill with that much compression As far as the cam I would look for a solid lifter flat tappet grind with as much lift you can get with between 245 to 260 degrees duration at .050 with the symmetrical lobes and maybe a little more duration(5 to 10 degrees) on the exhaust lobes and have it ground on 105 to 108 lobe separation angles and install it with between 3 to 6 degrees advance on the intake lobes As far as that clone M.W. intake for stock type 440 heads I don't know anyone who has used them and like them I'm a little bias on M.W. cars and motors due to owning and racing several of them, lucky me If I was advising your uncle I would tell him to run a six pack intake and carbs with 9.5 to 1 compression just to make some of the purist mad Mr.Cab Racing and winning with Mopars since 1964.

If so you will probably have detonation problems on todays pump swill with that much compression : Yeah Cab, I'm thinking it may have problems on pump gas.... But that's the cards I've been dealt with this build. Backstory of this motor, the longblock was apparently built in the 80s (guessing from the bearing date codes) and never used, My uncle bought it 10-12 years ago and got it running in his Dart with a single 4bbl and it sat... Last year at Carlisle he bought the cross ram setup and manifolds. Went to put the cross ram on last fall and noticed a loose rocker, further investigation showed the cam had a flat lobe...So he asked me to go through it. I cleaned and checked it out, new cam bearings, crank polished, and new rod and mains are on order. I know the pistons are TRW replacement 11:1 pistons. I'm hoping once I get checking piston height and head CCs that i'll end up with less than 11:1 compression. It previously had a Crane ZIP 510 solid FT cam in it. .ZIP-510 for the B/RB .340" intake lobe lift, .3455" exhaust lobe lift, Valve lash is .028" intake, .032" exhaust at operating temperature. The duration at .050" tappet lift is 254 degrees intake, 264 degrees exhaust. Lobe separation is 112 degrees.

I run 11:1 on pump gas with iron heads and I'm not having issues. He has some lobes just for stuff like this. It's worth your time to spend some time on the phone with him so you aren't guessing and doing it twice. Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid.

Seems any car with stock manifolds could only use so much duration and overlap. You could send him a pm for his input. 8.582, 160.18 mph best, 2905 lbs 549, indy 572-13, alky

All of them where drag race cams, not mild at all at that time There are a lot better choices on cams today for most any type build Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Not sure of the specs but around .520 and 250 something? The 413 and most of the 1963 M.W. motors where stage 1 motors, mid year in 1963 Mopar came out with the Stage 2 425 HP motor that had the same carbs and camshaft as the 425 HP 1964 M.W. came with. All the 1964 M.W. motors where considered and called Stage 3 is what I remember from back then I think all the 1963 cams where considered 300 degree total duration with right at .509 lift, the 1964 415 HP motors had a little more duration, either 312 or 316 degrees advertised with around .510 lift at the valves and the 1964 425 HP motors had the biggest wedge made for production cars with 320 degrees advertised duration and right at .520 valve lift All the Mopar ductile iron rocker arms I've check where no where near perfect, most didn't meet the 1.5 ratio, always less Mr.Cab Racing and winning with Mopars since 1964.

The MP .528 will pull hard and the car will seem really fast even if it isn't. It will be fun to drive on the street and sound good. If you put a real race cam in there then it might sound mean but it won't be any fun to drive.

Dwayne, theoretically, couldn't you just essentially order a "custom" grind through your cam supplier with the 528 specs for cheaper than what the MP cam cost?

In the context of the OP, i.e. street cruiser, exhaust manifolds, high street CR - not dedicated race engine. Throwing a lot of dyno time and more expensive components-i.e. roller cams, beehive springs, ect- there could be improvements here and there, but in the end it's a 1950s era engine.
