2012年10月18日 · The RV cam will make 3/4ths the amount of power that a 3/4 cam will. If you really want to kick ass you need a "full race" cam, or 4/4 cam. I think Dave Bruebeck had a 5/4 cam at one time.

2017年8月12日 · I'm building up a 283 SBC for my daily driven 53 Chevy and am just investigating what kind of cam I should go for. My setup is as follows: Fresh 283 - 30 over 416 heads from 305 sbc Camaro V8 T5 w 0.63 OD 3.55 Diff Quadrajet Torquer 1 manifold HEI distributor 17 lb steel flywheel

2021年4月13日 · Looked up a few modern grinds, the ever mysterious RV cam for comparison. These are very common replacement upgrade cams. Most lifts are in the .440 to .470 range, dur @.050 from 214-230. Above mid 230's starts to get into the range where vacuum suffers, a mild stall is needed, a sharp tuner can extend that range a bit RV CAM 1 (summit)

2018年1月16日 · I recommend RV cams for a daily driver. The duration matches a hydraulic cam's RPM limitations (220 or less degrees at 0.050" of lift), and has much more lift than a stock cam (approaching a half inch). It is a good choice for the street.

2011年2月1日 · edit: if anybody cares the above cam using the comp cams camquest program calls it a good torque, good mileage, good rv and towing cam. The graph shows torque to peak at 3500 rpm and HP at 4500. FWIW with 8.5:1 305 sbc it says 240hp@4500 and 325#@3500 rpm with 600 cfm dual plane

2010年8月22日 · Sounds like you have a severe Vacuum Leak or Valve train problem. 4 Degrees isn't much you should be around 10 Degrees BTDC with a RV Cam. Disconect and plug all Vacuum Sources Tranny Mod, PB, PCV, Vacuum Advance ... etc and put on a vacuum Gauge on her. It should be Stable; if not, you have Leaks in the Intake or a cam going south.

2014年6月12日 · Reher of Reher and Morrison was quoted as saying that the cams of today are so much better than the old days and even a cam like quoted above is better than any stock cam the specs are just more precise. You can never go wrong with a mild cam in your "Stock " motor. The Comp cams 268 is an excellent choice.

2009年12月7日 · What would be a stock cam in a 350 would be like an RV cam for a 283. What would be an RV cam for a 350 would be akin to a steet performance cam for a 283. So what does it really have???? Doesn't matter, no worries on the heads in either case. Good luck!

2015年5月24日 · On my 53 Chevy, I have a SBC 350 with an RV cam but everything else stock and rebuilt with not too many miles since. I have an Edelbrock carb. I bought a streetfire (made by MSD) distributor unit with the vacuum advance, rotor, cap etc. The directions say it is set up for 22 deg mechanical advance at 4000 rpm.

2015年5月7日 · I'd highly recommend putting a stock cam in it along the lines of a 300HP 327, 195/202 degrees @ .050, .390"/.410" lift. You get the advantage of keeping the valve train 100% stock incurring no added build costs and retaining stone-stock reliability. It should be at least a step up from the original 305 cam.
