Has anyone used a edelbrock rpm roller cam. Im building a 331 to replace the 302 Katrina ate. It appears to be easy on the valve train( long duration low lift ). I want to use AFR 185's and a weiand accelerator.
I use to run a pretty close combo to that a few years ago. except 302 based. with world Jr iron heads out of box. and that Weiand X-celolator maninifold with a 750 DP and Mac short tube headers, C4 with a 3000 stall and 4:10 gears I ran the same cam then as I am using now that being an Anderson Ford N61 cam.. It's nice an choppy up till 2100 but rated poor driveablility below 2200 ( I don't seem to have a issue with that before or now ) but that speced at 228/236 duration @.050 with .542/.568 lift @.050 with a 110 lobe sep.. the next cam down the N41 would be a really good choice for your combo but there not cheap they run about 300.00 .. the Trick flow stage 2 cam is pretty close to the same specs and I think it's around 170.00 or so... YOu can go more cam than that RPM with the 331 cubes you would really be limiting your power output In my opinion as that RPM cam is more for a stock 289/302 Cu. motor with smaller heads then the AFRs. your not going to take advantage of the AFRs flow capabilities with that little cam.. look for something with a bit more duration and more lift.. I would say around 220-240 duration and .520-.575 lift with a 110-112 centerline if it's going to stay N/A and 112-114 centerline if your going to add a power adder
Also make sure you get the recomended springs for what ever cam you decide to go with it can and will make a differnce in how it performs and lives..
use COMP Cams free cam support line and see what they suggest..
