If I find 2 Air Gap RPM's on the cheap, I'll buy them just to test back to back in a boat.
Same setup rebuilt to a 385ci, AFR 195R, 234/240 cam. Portmatched rpm AirGap to AFR 1205 gasket. Loved 6000+ rpms... IMO.... Under 6000rpms an RPM Air Gap is your friend... |

I recommend vic jr on many 502's where others recommend air gap rpms's. One engine is not another. |
I'm just curious how your going to like the 29 ftn in rough choppy water in comparison to the 27 magnum you previously owned. Btw what rpm did the 23's run at WOT. If in line with your peak hp I don't think your going to like the response in the boat. I've been down that road numerous times. More than likely your going to find it to be sluggish in comparison to the 23's unless your WOT rpm is way above 5,300 which I doubt very much. It's all about what you like to do and taylor to your needs. BUT.... I'd bet anything with the right cam and a little head work you could spin your 25's about 5,500 or the 23's 5,900 or so and see some nice speed gains. The difference btwn the 23's and 25's is probably close 400 rpm plus or minus. Probably could even be done without head work. BTW where did I miss what intakes your using now. I will look for cam in my 421 sbc. It's the king of cams for that build. Unbelievable torque. |
The Dart intakes are on the build parts sheet listed on page one under additional parts. It currently has 6200 rev limiters in it. With two in the boat low fuel I am able to hit the limiter. This is why I questioned where the motor should run based on the dyno sheets, thats beyound my expertise. I know from propping stock 350 mags you should be 46-4800. Sure I could prop down and spin 5000+ but thats not the happy area for the motor. Having more power and torque, I just feel like i should be spinning a bigger wheel. You guys have given me the info needed. When its time for freshening, I may bump the cams up. Currently has 30 hours on the build.
