THE DUDE
Apr 23rd, 01, 11:23 AM
The dude was wondering if anybody has used this cam and what they thought of it. It's going in a pretty hot 350. Does it have a good sounding idle and good performance?

Tracy Focht Apr 23rd, 01, 11:36 AM Great sound, but big cam. You'll need alot of stall for it. There is alot of advertised duration, but IMHO, there are better cams out there. ------------------ Speed-O-Motive 383 stroker kit, TRW forged pistons,10.7:1 compression, RPM intake, Speed Demon 750 cfm carb,World Products Sportsman II heads,2.02/1.60 valves, Comp Cam 1.6 roller rockers, Comp Xtreme 284 cam,ATI damper,Proform HEI and MSD6A box,HPC coated 1 5/8 headers, 2.5" exhaust with 40 series mufflers,TH350 with Hughes 3000 stall, Powertrax NoSlip Locker, 4.11 gears. boodlefoof Apr 23rd, 01, 12:20 PM it makes a better paper weight than a cam from what i have seen and heard. THE DUDE Apr 23rd, 01, 12:52 PM Its going in front of a TCI Streetfighter converter. I believe the stall is around 3000. Do you think this will be an appropriate stall speed for the cam? Big O Dave Apr 23rd, 01, 2:51 PM Tracy, I hope I'm not putting words in your mouth, but what I think you're trying to say is that there are other cams that achieve the same or greater maximum output, without sacrificing as much low-end as the Performer RPM does. Personally, I think it's a outdated design. Big O Dave ------------------ God, Family, Country, Chevrolet... and Volvos with Small Blocks in them.

I am running the Performer RPM cam in my 355 with a 3000 stall Coan converter and this thing has plenty out of the hole and top end.

Just couldn't spit it out... http://www.chevelles.com/forum/biggrin.gif I think the XE274 would be a better cam for your needs Dude. ------------------ Speed-O-Motive 383 stroker kit, TRW forged pistons,10.7:1 compression, RPM intake, Speed Demon 750 cfm carb,World Products Sportsman II heads,2.02/1.60 valves, Comp Cam 1.6 roller rockers, Comp Xtreme 284 cam,ATI damper,Proform HEI and MSD6A box,HPC coated 1 5/8 headers, 2.5" exhaust with 40 series mufflers,TH350 with Hughes 3000 stall, Powertrax NoSlip Locker, 4.11 gears. JohnC Apr 24th, 01, 3:36 PM I've heard the same thing, that there are better cams out there. I got a great deal on the heads though. For someone who is building a first engine and doesn't want to be disappointed, it's hard to argue with 420HP. I've seen a lot of magazine engine build ups using more expensive heads (AFR etc) that don't make that kind of HP. It's supposed to be very streetable (dont' have it in the car yet) too. That's why I went with the RPM cam. Back to the question on stall... I have highway gears (2.73 I think). I ordered the TCI 2400 rpm converter. Is this the right converter for the street? Thanks Big O Dave Apr 24th, 01, 4:38 PM The XE274-10 is a great cam... even more top end than the Performer RPM, yet more low-end, too. http://www.chevelles.com/forum/smile.gif You oughta see the torque curve with that cam in a 400 SBC with AFR 210 Comp Pkg heads at 10:1 - HOLY COW!! http://www.chevelles.com/forum/biggrin.gif Big O Dave ------------------ God, Family, Country, Chevrolet... and Volvos with Small Blocks in them.

You said with a 400 small block ,xtreme energy 274 cam and 210 AFR heads it would be killer.My setup will be a 400 with a 274 xtreme hyd cam ,10 comp ratio, rpm intake,750 DP,5.7 rods,1 3/4 headers.I talked to the reps at AFR and they said to go with the 190 heads.Do you know someone who uses the 210 heads with that cam.I havent ordered the heads yet and the short block is at the machine shop getting ready.Why would you say 210 would be killer? Big O Dave Apr 24th, 01, 10:59 PM Those heads were originally recommended to me by Mike Stark of CFM. When I ran the combo on DD2000 the hp/torque graph was a thing of beauty! See my response to your post "Big O Dave," too. Big O Dave THE DUDE Apr 25th, 01, 5:45 AM So how did the power brakes work after putting in the RPM cam? boodlefoof Apr 25th, 01, 6:34 AM In the articles, sometimes the AFR heads don't make as many horses as the 420 that the RPM package claims, but look at the most recent CHP. They have an article with a 350, AFR heads, 9:1 compression, and a much smaller comp XE268 cam. It makes 415 horses, but the big story was torque. It made 400+ ft. lbs. from 2900-5400rpm. The edelbrock package only tops 400 ft. lbs. for about a 1000rpm spread. The torque peak with the XE268 and AFR heads was also 435 ft. lbs. and it made 430+ from 3600-4600 or something like that. This while idling at 700rpm and pulling plenty of vacuum for power brakes. Also, with the edelbrock cam I think they recommend 3.55 gears or so. The RPM package with cam is supposed to draw 11'' of vacuum at idle, might be low for power brakes. THE DUDE Apr 25th, 01, 7:49 AM On the engine that I am buliding I am using the complete Edelbrock power package except for the heads. Instead of the aluminum Edelbrock heads I am going to use Dart Iron Eagle heads with the 200cc intake runners and Manley Street flo valves. Do you guys have any idea how these heads will perform in relation to the Edelbrock heads? I was hoping to still get around 400hp at the flywheel. marooned Apr 25th, 01, 6:50 PM Engine idle 850 RPM. Complete Power disc brake Kit from True Connections. (12" rotors) They will put your head through the windshield. No problem. This Summer I plan a couple passes down the ole 1320. I'll post the times when I do. http://www.chevelles.com/forum/cool.gif ------------------ 1965 Chevelle Maroond Maroon 65 (http://www.chevelles.com/showroom/marooned65.jpg) | ||
