and the bottom right hole is flat. thats what did me in last year
I'll bet NA it'll make 400hp given those heads and intake, if the cam is supposed to run to 5500-6000rpm. The torque peak might be in the 3700rpm range, again assuming the peak is aimed at around 5500 or so. If it's over 4000rpm, then the cam might be a little big, made for more rpm than you want. I think I'll want mine to shift before 6k. The springs and lift are big factors in that rpm band choice. I hope a custom cam can be made to be more reliable if it's asked for(limit the lift etc).Thanks Tim, its interesting. I would have thought even the aftermarket (GMB,etc.) would have been Ford factory catsting rebuilds, but thats apparently not the case.
Don, back to your thoughts on the springs you have for your heads, here is what my engine builder is using.
Valve Spring | PAC Racing Springs
The spec's are there, so it will hopefully help you.
Honestly, I would expect that FlowTech inductions is excellent, but with the continued calamity of errors with the motor rebuilding over and over an issue showed up. Its interesting that the cam card spec'd the lower pressure springs also. I'm betting that this spec had more to do with a spec that was recommended with the core, rather than FlowTech's determination.
I am interested in dropping my new motor on the engine dyno for many reasons:
1. The builder and I know beyond any shadow of a doubt that if a thrust goes again, its purely my issue. I think we have determined that already.
2. After the dyno, the builder will look at the oil, pull the pan off and look for issues, and pull a valve cover off to look for issues.
3. I will see in N/A form what timing makes best power at different rpm's. Peak torque RPM will also be interesting. This will be helpful in tuning.
4. The experience
To a lesser degree, the over all HP/Torque the motor makes at the flywheel N/A will be interesting
So you had rubbing problems with the FlowKooler Brand or did the quit making them?My water pump finally showed up. Nice piece, but made in China. On this one, the impeller does not rub and the quality appears to be there. Its a keeper.
Thanks.Rubbing issues, and on back order for another one. On-line there are many other reports of poor quality control.
I decided the best bet is OEM. That combined with a Mr. Gasket high flow 180 degree thermostat and I will have added protection to what was a non-problem anyway.
I like that, I too would want a revamped cam selection, given the wear of the cam lobes etc. I hope that issue was an odd mismatch of lobe choices and springs. If we were neighbors, and money/labor was no issue, I'd offer to pull my 347 cam out and let you try it. I had it made for a medium boost turbo application, intended to run NA initially. I gave up on that thought for my Lincoln, that'd be nuts in the car. It's made for Canfield heads, which are just above what the 170's were made for.Don, the cam will not be ordered till after the heads are flowed. With a higher flowing motor, I'd expect peak torque to come down. Also, the turbo will come on much earlier and that will give me the torque much lower in the rpm band. Its all hypothetical, we will see what happens.
I KNOW THIS IS AN OLD POST BUT LOVE IT.... being my Cam synchronizer is STILL stuck in engine!synchronizer
I would soak it with carb cleaner to loosen it up, then pull it out. I would then take it outside and beat mercilessly on it without holding back at all, until I felt better.
Then I would do a victory dance on it.
After that I would probably look around to make sure no one saw me.
