Hi, has anyone used this camshaft before? I plan a mild 440 build and can get this camshaft at a clearance price. Any input would be great.
Thank you
Thank you
I have noticed Summit cam's have similar grinds.It is almost the identical specs to the larger Summit cam.
Thanks for your reply, can I ask about your engine? Did you have any head work done, O/S valves etc. Did you use a high stall convertor?I used that in my 400. It was a great street cam.
Thanks, your engine sounds pretty much like I plan to build. I have Edelbrock heads from a previous build I didn't use and was hoping to get away with using a stock convertor.That engine had pocket ported 452 heads with 2.14/1.81 valves. It was 9:1 compression with a Weiand dual plane and a 750 carb. It made 415 HP and 450 lb/ft of torque. I was using a 2500-3000 stall converter, but I'm not sure that would be necessary with a 440.
your peak torque is not coming in till 4000 rpm and peak HP not till 5600 rpm just like I said. nothing I would want for a nice street engine. for the strip maybe with lots of converter and gears. The intake lift is close to a stock Mopar magnum engine. with a right cam you could have been in the mid 12'sHere is a printout of the dyno sheet for my 400 build with that exact cam. It had a really flat torque curve, and the 114 lobe separation helped the idle quality and vacuum. It ran high 12's in my 1969 Barracuda.

Just make sure you degree it properly or it you'll have poor performance.Hi, has anyone used this camshaft before? I plan a mild 440 build and can get this camshaft at a clearance price. Any input would be great.

Thanks for the heads up.Word of warning...
Before Crane went bankrupt their quality control on their products went down the tubes, if possible I would double check things before installing..
Just my $0.02...![]()
Thanks, there is another version of this cam from Crane, exactly the same but with lower LSA. Unfortunately, this is not the one on sale.What post #9 said about LSA. LSA needs to be tighter. After D. Vizard tested 000s of cams for Crane, many of the wide LSA cams were dropped & they now have tighter LSA.

the wide LSA is 75% of the problem the other 25% is the big spread between intake and exhaust which also hurts your low end torque. the only thing the big exhaust duration does is keep your power from dropping off after you reach peak HP.What post #9 said about LSA.
